Part arrived faster than expected. Fit perfectly and compressor is back running again. Your site made it easy to find the correct part.

Hard to find parts
Needed a specialty serpentine drive belt and inlet air filter for a 1973 vintage Craftsman air compressor. The V-grooves in this belt are narrower and shallower than those used today which prevented a cross-over at the parts stores. The inlet air filter is specific to the older design cast iron compressor. Replacement Parts was able to supply both. The price was reasonable and delivery was timely. WDL

Wrong part received it was different than the part listed
I received the part not terribly quick, the part was wrong, I received a poly V belt instead the flat 6 groove belt pictured on the listing. Also a review listing the picture asked a question about the flat belt 6 groove. And the reply also stated “ yes it is a flat belt” I ordered and now had to return it and it cost $5.50 for return shipping, I’m out for their mistake

Sorry, we couldn't find any existing installation instruction that matched.
After 44 years of service, the compressor was leaking lube oil from the shaft seal and the pulley/flywhell retention set screw loosened, destroyed the crank key.
1. Removed the compressor unit from the tank mount.
2. Disassembled the compressor, determined replacement parts, and cleaned all parts.
3. Researched torque values for connecting rod, head, and end cap bolts.
4. Procured gasket material and made gaskets for discontinued part numbers.
5. After receiving replaceme
... Read morent parts, reassembled and remounted compressor unit.
6. Installed new drive belt, although the original was still good after all these years!
NOTE: Torque values are extremely important! DO NOT OVER OR UNDER TIGHTEN FASTENERS!
Pulled the belt guard off, loosened the drive motor and replaced the worn belt with the replacement belt. Adjusted the belt tension and replaced the guard. Tested the compressor. 20 minute repair time.

My air compressor drive belt, part number BT003100AV, was worn out

The main problem is removing and replacing the belt guard. This guard is a long five sided box completely covering the belt held on by about eight bolts. One of the bolts holding it is under the plastic covering over the cylinders, so that had to be removed as well. One of the bolts is located between the motor and the cylinder housing
... Read more and all but impossible to get to without a long extension on a ratchet drive. Replacing the belt and adjusting it was a snap once the guard was off. Just loosen the motor mounting bolts, replace the belt, and tighten the motor bolts down with the belt tension such that it will turn the compressor. Getting the belt guard in place and holes lined up was another matter. By using the punch to hold alignment in one hole I was able to get a bolt started in another hole. I did not replace the bolt under the cylinder housing. I have a large well equipped shop and do lots of repair work, so this was not a problem for me. Someone less mechanically inclined would not be able to get that belt guard off.
