  1. central pneumatic 90234 both wheels are broken. have been many places looking for something that will work ,, any suggestions

    • You can call Harbor Freight Customer Service at 1-800-444-3353 or simply take one of the broken wheels to a local Home Depot/Lowes to see if they have the same size. A lot of times wheel sizes are shared across various equipment.

  2. I need a manual for a 40400 air compressor, 2 HP – 8 gallon. Any help would be appreciated. Thanks

    The following is on the page after clicking on the link:

    The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.”

  8. I have a manual for my 62299 but can’t find any parts for it….. PMO…. you get it for a good price but if you can’t find parts for it and are down for a period of time that costs….

  9. I have a 2Hp -8 Gallon Central Pneumatic air compressor # 234578. The check valve is cracked and leaking. I have ordered replacement parts twice on line each one of them arrived with wrong threads. I cannot find the manual on line and Harbor Fraight help line cannot find the darn thing. I am frustrated. Can anyone help.

    • All the fittings are made out of cheap metal and crumble easy. I noticed that the threads all seemed to be slightly off for some reason. The copper pipe is just a tad to wide. I had to grind the compression fitting a little bit to make it slide on to the pipe. I think they must have gotten a good deal on all the pieces because they didn’t meet the standard in production. I have to use a lot of Teflon tape on the threads to get them to deal properly. Jb weld might be useful. I also had to replace the pressure switch. It’s almost not worth repairing the compressor unless you are stubborn like me and have to try fixing things before throwing it out.
