Harbor Freight 29 gallon cast iron air compressor (68127) - Break In - Part 2
Video of me breaking in my new Harbor Freight 29 gallon cast iron air compressor (68127). I retorqued the head twice for the pre and post break-in run. The min/max spec for the headbolts are 22/27 N-M. I torqued the headbolts to 22NM for the pre-run and the headbolts to 26NM after the break-in run. Head was cool to the touch. I then did a tank fill-up. It took about 6:35 mins and stopped at 150psi (In the video, I said it stopped at 145psi, but I watched it again today carefully and the compressor cuts out exactly at 150psi, but minutes later, the needle settles right below 150psi).
Proper break in of Harbor Freight central pneumatic 29 gallon 2hp 150psi air compressor model 68127
Well, santa was good to me this year. This is my new harbor freight central pneumatic air compressor. This is what the manual concludes as proper break in procedures, you are supposed to check the compressor head bolts before initial run and after the 10 minute no load pump break in and again every 500 hours. They are supposed to be torqued at 27nm (just about 20ft lb.). I always change the oil in chinese equipment even before the first start up because I don't like their quality of oil and there is usually some metal remnants in the oil if they test run at the factory and just leftover from casting parts. I then put in good quality oil, run it once or twice and change it again to make sure I get all the metal particles out of the case. I shot this over a few days because my health condition really really really limits me for doing anything longer than 15 (or less) minutes at a time. Hopefully that will change very soon. As you can see I got this at christmas and I just got done shooting and uploading video. This looks to be a decent compressor, but won't really be able to test it out until after my surgery and recovery, which won't be till about march at the earliest. I don't work for harbor freight nor central pneumatic, just following the manual and my own take on some things. I've had great success with some chinese manufactured tools and equipment, and I've had some great disasters as well. It's best to look at the item you are considering in the store, and do lots of online extensive research before a major purchase. If you plan on using the item heavily or every day, I would buy a used name brand tool thats easy to get parts for or fab parts for before I bought a chinese one. This will see use about once a week or even longer intervals, so it should be ok. Also, I would not buy ANY chinese oil less compressor for two reasons, they wake the dead and they typically fail apart within the first few uses if not shorter. This is a Central Pneumatic ( Distributed by Harbor Freight ) 2hp 150psi 29 gallon 115v single phase two piston pump single stage vertial air compressor part number 68127 I will also upload a second video very shorty showing tank fill time from 0 psi to full 150 psi I wish this model had pneumatic tires, would make moving it around much easier, I may have to adapt it to use a set in the future.
Compressor Update 29gal 2hp 150psi Central Pneumatic Air Compressor
21 Gallon compressor just doesn't cut it. This compressor is also MUCH quieter than the 21gal.
Harbor Freight 29 gal air compressor 3 HP pump upgrade.
Sorry for the restless smart phone movement I normally use a tripod: I am upgrading the compressor pump with a 10.0 CFM @ 90 psi cast iron harbor freight compressor pump. The new pump requires a 3 HP motor, I have a 5 HP but in this video I am overloading the 20 amp breaker with the 2 HP motor. I later added the 240 volt 5 HP motor from my old Sears unit I had taken apart do to rusted out 30 gal tank.
