(3)- Mating the 54mm cylinder to Stroker Crank
This is the tricky part of compressing both rings while trying to manouver
a 4 kilo iron cylinder above them. It does not help with my slightly stiff,
50 year old hands. It should be a snap for you young guys. RH
Many of you have seen this one before. I apologize if bringing it back
Domestickilla gave me a crankshaft, and it's a nice one that I want to
clean up and use again. You'll be seeing a lot of it and because of this,
this video deserves to be here. I fixed what I broke, and this was my

Yamaha YZF R1 crossplane crankshaft technology explained
The crossplane or cross-plane is a crankshaft design for V8 engines with a
90° angle between the cylinder banks. The crossplane crankshaft is the
configuration used in most V8 road cars.3d model of a cross-plane
crankshaft demonstrating the 90 degree angle between the crank throws and
the large counter weights.The crossplane crankshaft has four crankpins,
each offset at 90° from the adjacent crankpins. The first and last of the
four crank pins are at 180° with respect to each other as are the second
and third, with each pair at 90° to the other, so that viewed from the end
the crankshaft forms a cross. The crankpins are therefore in two planes
crossed at 90°, hence the name crossplane. A crossplane crank may have up
to five main bearings, and usually does, as well as large balancing
weights. Crossplane V8 engines have uneven firing patterns within each
cylinder bank, producing a distinctive burble in the Exhaust note, but an even firing pattern
overall. Their second-order balance, owing to the 90° bank angle and 90°
throws, means no additional balance shaft is necessary to achieve greater
smoothness. Without the 90° bank angle, a balance shaft may be required.
The other prominent design for a V8 crankshaft is the flatplane crankshaft,
with all crankpins in the same plane and the only offset 180°. Early V8
engines, modern racing engines and some others used or use the flatplane
crankshaft, which is similar to that used in a straight four or flat-four
engine. Flatplane V8 engines may use any angle between the cylinder banks,
with 60° and 90° the most common. They lack the V8 burble and the
superior mechanical balance of the crossplane design, but do not require
the large crankshaft balancing weights. Inherent balance of the big ends is
like a straight four, and modern designs often incorporate a balance shaft
for smoothness. But without balance shafts, flatplane designs have the
least flywheel effect of any V8s, which allows them to be more
The crossplane design was first proposed in 1915, and developed by Cadillac
and Peerless, both of whom produced flatplane V8s before introducing the
crossplane design. Cadillac introduced the first crossplane in 1923, with
Peerless following in 1924.
Inline-4 engines can also use the crossplane concept. The 2009 Yamaha
YZF-R1 motorcycle uses the crossplane crankshaft and, in the absence of the
90° bank angle of the V8, must use a separate balance shaft geared off the
crankshaft to eliminate the inherent vibration (a primary rocking couple)
found in this type of crank.
A crossplane crank has been used in Yamaha's M1 MotoGP racing models in the
past. Yamaha claims advances in metal forging technologies make this a
practical consumer product.
Blueprint 104 - The Crankshaft
It's important to know what you've got even before dealing with the
machinist. If you want to inspect a crankshaft, this is how you do it. I
detail the process of removing the crank and what to measure. All
specifications in this video are illustrated with a 6-bolt 4g63 turbo block, but are all actually the same for
7-bolt engines with the exception of the rod widths.

I haven't seen anybody use this method yet. I am too impatient to put
things in the freezer overnight and don't like feeling like I'm in a race
against time to keep the bearing cold. This method obviously works quickly
and easily if you're careful. Playing with a torch and liquid CO2 is
obviously dangerous. Both can cause you quite a bit of pain if you're
How to Remove Stubborn Toyota 20R - 22R - 22RE Crankshaft Pulley Bolt 1979 - 1995
A long (but detailed) video on the tips and tricks I've learned over the
years on how to remove stubborn crankshaft pulley bolts on Toyota 22R
series engines. (22R 22RE 22RET)
By far, the best way would be to have the SST (shop specific tool) that
Toyota recommends, but not many folks (me included) has one of those in
their garage. This is a video of some of the tips and tricks that I've
learned over the years on getting this sometimes EXTREMELY stubborn bolt to
The most common reason that you need to be able to get this bolt out is so
that you can access the front main seal on the front end of the crankshaft.
Most older Toyotas develope an oil leak through the seal. Oil works past
the worn-out seal and then gets flung around the front of the engine and
engine bay by the crankshaft pulleys. It's really a pretty easy fix for a
very messy problem...if you can get the crankshaft pulley bolt off in order
to access the seal.
