REMANUFACTURING PROCESS
Below are the 16 steps we use in our engine block remanufacturing process. To view our cylinder head and crankshaft process click the PROCESS link on the navigation menu above.
STEP 1) ENGINE BLOCK DISASSEMBLYAll blocks are visually inspected for casting defects prior to their disassembly and the beginning of engine block remanufacturing. The parts are then removed and individually inspected for damage and cause of failure. The oil and water passage plugs are removed to insure optimum results during the thermal cleaning process.
Only premium castings are used for our marine blocks, all castings are replaced in all salt-water applications. Our high performance engines are built with premium cores. In many applications new castings are used, as we never employ repaired castings or sleeved blocks. To retain your classic car's original block casting, Promar employs the artistry of our skilled casting repair technicians.
Dirty Engine Block
The thermal cleaning system gives our customers the closest thing to a new casting, taking engine parts to a whole new level of clean. The heaters emit uniformly controlled heat, which is evenly distributed throughout the chamber. This method totally eliminates the concentration of intense heat or flame entering the chamber, which could overheat, warp or melt parts. The load is heated to 650-800 F (340-427C) in an oxygen deficient atmosphere, where the combustible hydrocarbons decompose and parts leave the oven completely dry. This baking process used on cast iron blocks only employs the Ace RKE 230 oven. Ash residue is easily removed by stainless steel shot blasting which is the next step of our engine restoration services.
Oven-Cleaned Engine Block
Our shot-blasting machine employs a cleaning method using stainless steel shot. This finishing process is used by Promar to remove surface contamination such as rust and irregularities from engine blocks during remanufacturing. The result of this method is a cleaner smoother surface finish to make easy the detection of surface and subsurface casting defects during quality inspection.
To insure stress free casting, the peening process is used to impart compression strength to metal parts. This is accomplished by metal shot pellets acting like miniature ball peen hammers as they strike the entire surface of the block. All iron castings are put through this process before a preliminary inspection for defects is done. This process using the AR HB41 is employed for cast iron blocks only and facilitates a more accurate magnetic particle inspection.
Engine Block After Shot Blasting
Magnetic particle inspection is the most definitive method of detecting cracks and imperfections in any ferrous engine parts. This procedure, as part of our engine restoration services, assures the highest quality cast iron blocks. The next process is pressure testing, but first, let us explain how aluminum blocks are cleaned, pressure tested and checked for casting defects.
Engine Block Crack Detection
The first stop for a qualified aluminum engine block during remanufacturing is our AXE SW20 OS spray cleaning system. With twice the spraying power and a dramatically increased number of multi integrated spray nozzles, this state of the art system assures Promar that all oil, dirt and foreign material is removed from even the smallest of oiling holes. Cleanliness of the aluminum engine block is essential to insure an accurate inspection. This process is used on all aluminum engine blocks as a first step prior to the second step of ultrasonic cleaning.
AXE SW20 OS Spray Cleaning System
Promar's second process in the cleaning of aluminum blocks is the ultrasonic cleaning method, long known as the "benchmark" in cleaning and engine restoration services. Hundreds of specifications reference an ultrasonically cleaned part as the ultimate target for cleanliness. Ultrasonic cavitation is able to clean right down to the surface of a part and beyond. It is also able to reach internal areas, which are not accessible by using other cleaning means including spray and mechanical agitation. The forceful nature of ultrasonic energy provides the physical "push" required to break the mechanical and ionic bonds that hold very small particles to surfaces. Once cleaned the block is sent for pressure testing.
GMC 1818B Ultra Sonic Cleaner
Promar uses the Delta Pressure tester to double check for pin holes after magnafluxing and dye testing are completed. Cracks and defects not detected during the first process are found at this time. This second process insures the integrity of all castings used in Promar products.
Delta 6000 Pressure Tester Machine
A complete visual inspection of the block is performed. Repairs will be made to minor casting defects, removal of broken bolts are performed as well as repair and tapping of threads. Gasket surface repairs are performed to minimize stock removal. The next step of engine block remanufacturing is align honing.
Engine Block Preparation
Align honing is the best method for precision alignment of main bearing bores. Promar uses the Sunnen CH-100 machine for all of its benefits and features, as we can minimize stock removal, usually less than .003" (.076 mm) off the caps compared to as much as .010" (.254 mm) with boring.
Use of this machine maximizes precision and corrects distortion caused by warpage and cap stretch. This align hone procedure exceeds original factory accuracy for alignment, roundness and size and precedes the engine boring process.
Engine Block Align Honing Process
Promar employs the Rottler F54X boring bar with its large diameter and hard chromed spindle. This spindle is supported on adjustable tapered bearings for superior accuracy. The F54X uses a precision ground ball screw to control feed rate and cutter position. By controlling these factors the machine can repeat cutter position accuracy to .0002" (.005mm). With its digital programmable cycles, the F54X allows boring depth to be programmed to .0001" (.0025mm). The next process of our engine restoration services to follow boring is milling.
Rottler F54X Boring Bar
Engine Block Boring Process
Milling machines that are used by Promar are set up specifically for blocks. The Winona Van Norman M3000 machines are used for their variable feed rate, which is essential to acquire proper Ra finish for each block. Ra finish determination is based on the type of block, be it aluminum or cast iron, and by the type of gasket used for each specific application. These machines utilize CBN (cubic boron nitride) cutters, which are second in hardness only to a diamond. During the cutting process heat from friction is absorbed and carried off by the discarded metal chips thus resulting in improved accuracy and excellent surface finish. The surface finish is then checked by using the Mitutoyo SJ-301. The Mitutoyo SJ-301 is utilized twice, once after resurfacing and again before final assembly Promar insures proper measurement of Ra by using the SJ-301. The next process of engine block remanufacturing is rod reconditioning.
M3000
Engine Block after Milling Process
The ideal equipment for precision rod reconditioning and pin fitting is the Sunnen LBB-1600 Hone, which measures accuracy within .0001". This hone method is preferred all over the world for its ability to produce a round and straight honed bore equal to or better than the manufacturer's new rods.
All high performance engines are fitted with ARP high strength bolts and nuts prior to rod reconditioning. Once reconditioning of the rods is accomplished the next step of engine restoration is honing of the cylinders.
Sunnen LBB-1600
Connecting Rod Bore Checking Process
Promar steps out of the Stone Age and into the Diamond Era with the purchase of their new Sunnen SV-10 Diamond Cylinder Honing Machine. Honing hundreds of blocks a month, Promar could not pass up the opportunity to buy the machine with the perfect combination of machine tooling and abrasives for precision automatic cylinder honing. Promar was using Sunnen’s CV616 honing machine where, at times, even an experienced operator could struggle to get desired results. The new SV-10 machine can not be matched when it comes to the roundness, straightness and finish quality of its Diamond Honed cylinders. The machine is equipped with a patented full-bore profile display which shows a real-time cross section of the bore, taking the guesswork out of removing taper. For unattended operation, the auto dwell feature will automatically dwell the honing action in the tightest areas of the bore. The machine also offers infinitely variable crosshatch angles for any bore diameter and cylinder length – all of which can be changed on the fly.
Promar insures proper measurement of Ra by utilizing the Mitutoyo SJ-301 twice, once after honing and again before final assembly. Final assembly and completion of engine block remanufacturing is not started until all blocks go through a final wash.
Sunnen SV-10 Diamond Cylinder Honing Machine
Engine Block Honing Process
Following these precise machining procedures and engine restoration services, our blocks undergo a second high pressure wash cycle to guarantee the removal of any debris that may have adhered or become dislodged during the machining process. Absolute cleanliness is necessary for the next step, which is final assembly. After the blocks receive a final wash we clean all parts ultrasonically.
AXE SW 20-OS
Promar's second process is ultra sonic cleaning of all parts old and new prior to assembly of the engine. This Ultrasonic Cleaning Method is long known as the "benchmark" in cleaning. Hundreds of specifications reference an ultrasonically cleaned part as the ultimate target for cleanliness. Ultrasonic cavitation is able to clean right down to the surface of a part and beyond. It is also able to reach internal areas, which are not accessible by using other cleaning means including spray and mechanical agitation. The forceful nature of ultrasonic energy provides the physical "push" required to break the mechanical and ionic bonds that hold very small particles to surfaces. Once the parts are cleaned, they are now ready to be assembled in our Promar engine.
GMC-1818B Ultra Sonic Cleaner
At Promar there are no assembly lines during engine block remanufacturing. All engines are custom built. Each assembler does a visual inspection of the block, heads, crankshaft and all-inclusive parts prior to assembly. The Ra tester is used to check all cylinder bores, crankshaft journals and gasket surfaces. All parts such as crankshafts, bearings, cylinder bores, pistons, rings, connection rods, main saddles, lifter and camshaft bores are miced for proper size.
Each block is fitted with new full circle cam bearings, oil restrictors, relief valves, new water and oil plugs. The crankshaft is fitted in the block with new high quality bearings and each journal clearance is checked with plastigage, torqued and double-checked. New rings are then fitted in each bore to assure proper end gap. Each new piston is checked for proper clearance in each bore. The rings are installed on the piston and assembled into the bores. Each assembly is supplied with new high quality bearings and each journal clearance is checked with plastigage, torqued and double-checked. A new camshaft is then fitted into cam bearings bores and all new timing components are installed and double-checked by an assembly manager.
Cylinder heads are then installed with new head bolts and new Felpro or Victor head gaskets. The block now receives new lifters, push rods and rocker arms which are adjusted and a second check completed by an assembly manager. Each cylinder is then accurately checked for seal integrity to assure no compression or water leaks. At this point the engine is primed with special lubricant and a new oil pump. The residual parts of the gasket set are sent along with the engine. The assembly manager then conducts the final inspection of the engine.
All engines come with an installation manual. Bulletins about your specific engine are also enclosed in the packaging. Promar engines are secured onto a wooden pallet where vulnerable parts are protected from damage by corner covers. The entire block is wrapped in a durable plastic sheath to protect your engine from outside elements.

The next process of cylinder head repair is pressure testing, but first, let us explain how aluminum cylinder heads are cleaned, pressure tested and checked for casting defects.
Magnetic Particle Inspection Process
The first stop for a qualified aluminum cylinder head during remanufacturing is our AXE SW20 OS spray cleaning system. With twice the spraying power and a dramatically increased number of multi integrated spray nozzles, this state of the art system assures Promar that all oil, dirt and foreign material is removed from even the smallest of oiling holes. Cleanliness of the aluminum cylinder head is essential to insure an accurate inspection. This process is used on all aluminum cylinder heads as a first step prior to the second step of ultrasonic cleaning.

Promar's second process in the cleaning of aluminum cylinder heads during repair is the ultrasonic cleaning method, long known as the "benchmark" in cleaning. Hundreds of specifications reference an ultrasonically cleaned part as the ultimate target for cleanliness. Ultrasonic cavitation is able to clean right down to the surface of a part and beyond. It is also able to reach internal areas, which are not accessible by using other cleaning means including spray and mechanical agitation. The forceful nature of ultrasonic energy provides the physical "push" required to break the mechanical and ionic bonds that hold very small particles to surfaces. Once cleaned the cylinder head is sent for pressure testing.

Promar uses the Delta Pressure tester to double check for pin holes after magnafluxing and dye testing are completed. Cracks and defects not detected during the first cylinder head remanufacturing process are found at this time. This second process insures the integrity of all castings used in Promar products.

Pressure Testing Process
During the head preparation and after pressure testing, minor cylinder head repairs are carried out. Broken bolts are removed and repair and tapping of threads completed. Gasket surface repairs are accomplished in order to minimize stock removal. All guides are inspected for replacement or fitted with new oversized valves. The heads are now ready for line honing.
Broken Bolt Removal Process
Line honing is the best method for precision alignment of overhead camshaft cylinder head bores. Promar uses the Sunnen CH-100 machine for all of its benefits and features, as we can minimize stock removal, usually less than .003" (.076 mm) off the caps compared to as much as .010" (.254 mm) with boring. Use of this machine maximizes precision and corrects distortion caused by warpage and cap stretch. This line hone procedure during cylinder head remanufacturing exceeds original factory accuracy for alignment, roundness and size.

In cylinder head machinging, classic car heads previously designed to use leaded gas must be updated with seats and valves compatible for use with unleaded gas. Marine and high performance heads are fitted with new guides before valve seat resurfacing.
STEP 11) CYLINDER HEAD SEAT REFACINGPromar's head machining center has a rigid head and base enabling delivery of high precision multiple angle seat to guide concentricity within .001 or less per 1" of valve diameter. The variable speed cutter head on the DMC series 2000 assures chatter free seat finish. All seats are checked with a vacuum tester while still on the machine. A second check is done after final assembly to insure optimum valve and seat seal. The next process during cylinder head repair is milling of the heads.
HCM-2000
Valve Seat Resurfacing
Milling machines that are used by Promar are set up specifically for heads. The Winona Van Norman M3000 machines are used for their variable feed rate, which is essential to acquire proper Ra finish for each head. Ra finish determination is based on the type of head, be it aluminum or cast iron and by the type of gasket used for each specific application. These machines utilize CBN (cubic boron nitride) cutters, which are second in hardness only to a diamond, to maximize quality work during cylinder head remanufacturing. During the cutting process heat from friction is absorbed and carried off by the discarded metal chips thus resulting in improved accuracy and excellent surface finish. Promar insures proper measurement of Ra by utilizing the Mitutoyo SJ-301 twice, once after resurfacing and again before final assembly.

Surface Ra Testing
All heads are then washed with a mild detergent and rinsed before the final assembly.
Cylinder Head Washing Process
At the time of assembly, Promar installs new oil and water plugs in all its cylinder heads, using brass plugs in our marine applications. The springs are checked for proper pressure as well as the installed heights checked and new Viton seals installed. All our overhead cam heads include new cams, rockers, lifters and cam seals.
The final assembly process is accomplished using the CHW-50 Cylinder Head Workstation. This machine takes the work out of head assembly and disassembly. It makes precision automotive head rebuilding easier than ever. The entire valve train, including cams, rocker arms, cam buckets, springs, valves, etc. can be easily removed, reinstalled and adjusted while the head is mounted in the workstation. Once final assembly is completed the heads are vacuum tested and then wrapped.

Below are the 8 steps we use in our crankshaft remanufacturing process.
STEP 1) CRANKSHAFT DISASSEMBLYCrankshafts are removed from the engine blocks so a visual inspection of the crank casting can be done. Crankshafts with bad keyways, journals spun beyond machining specs or worn thrusts surfaces will be discarded. Adhering to strict quality standards, Promar will never use a welded shaft. Once qualified in preliminary inspection, the crank is then sent for initial cleaning.
Dirty Crankshaft
The first stop for a qualified crankshaft during our crankshaft repair process is our AXE SW20 OS spray cleaning system. With twice the spraying power and dramatically increased number of multi-integrated spray nozzles, the state of the art system assures Promar that all oil, dirt and foreign material is removed from even the smallest of oiling holes. The cleanliness of this crank is essential to insure an accurate magnetic particle crack detection test.

Continuing our efforts to produce the best and most reliable crankshaft repair product in the industry, we utilize the Berco RTM 225A precision crankshaft grinder. Coupled with our expert craftsmen, this state of the art unit incorporates rigid construction and precise controls; affording Promar customers the most accurately ground crankshafts possible. Precise controls afford precision grinding, which is followed up by brush cleaning and chamfering of all oil passages.

Crankshaft Grinding Process
Following these precise machining procedures, our cranks undergo a second high pressure wash cycle to guarantee the removal of any debris that may have adhered or become dislodged during the grinding process. Absolute cleanliness is necessary for the next step of crankshaft remanufacturing, which is micro-polishing and or balancing if needed.

Promar's digitally controlled balancer is extremely accurate, producing precise balanced crankshafts during repair, it has the ability to measure unbalance from .01 to 1,000 grams on work pieces weighing up to 500 lbs. (226kg). This process using the Sunnen DCB 2000 is optional for this application.
Sunnen DCB-2000
Crankshaft Balancing Process
Promar uses a crankshaft micro polisher with a rigid polishing system during remanufacturing. The QPAC Q190-38-3 has a solid abrasive tape that wraps around the journal and is backed up with a shoe. This shoe applies equal pressure all the way around the journal while it is being polished.
Traditional polishing techniques use a manually operated belt sander that can alter the geometry of the journal, slightly creating some taper or out-of-roundness. If the surface finish on the crankshaft journal is not right or the geometry is slightly off, the bearings will suffer the consequences when the crankshaft is put into service. While polishing in one direction and then automatically polishing in the opposite direction, the QPAC system leaves a better finish and eliminates microscopic peaks that can cause premature bearing failure. The finishing process always ends in the same direction as the engine rotation.
For thrust surfaces, a separate polishing arm is used. Polishing the thrust surface on the crank is important to minimize the risk of thrust failure on vehicles that have electronic torque converters.
With many of today's engines requiring extremely smooth journal finishes (as low as 6 Ra or less) because of tighter bearing clearances and the use of thinner viscosity 5W-30 motor oils, there is little margin for error. In one pass the QPAC takes the finish down to 6 Ra or less and provides a superior finish to any polishing systems out there today.

Our spray cleaner system carries twice the horsepower and twice the amount of nozzles than most spray cabinets. This machine assures Promar that any dirt, metal or oils from crankshaft repair and remanufacturing are removed before final assembly. This is the third and final wash performed after the micro polishing.
