hello everyone
I got my major rebuild kit and I have no idea how to remove the piston and counterbalance from the axel.
any ideas??
it was very noisy and when I opened it up the shims holding the piston to the bearing were gone.
See if Steve's write up on our old blog has relevant info: HWH Pump Rebuild (https://www.irvblog.com/foretravel%20projects/HWH-Pump-Rebuild/)
I did and it does not detail anything about the painfull removal of the bearing and counter balance.
i went to the part store and got a pulley puller and i managed to damage the piston rod
back to square one.. i need to find a piston rod replacement.
After i pulled the old piston and counter balance off( it was hard because of their offset and first i pulled the bearing and the counter balance and then i had to pull the center piece that goes inside the bearing and that its offset as well an i was only able to pull from the sleeve that is behind it.)
after i reinserted the new piston rod i inserted the counter balance at the same time and moved them towards the end together and then i realized that the metal shaft pin would not go inn because the counter balance was smashed and i should have pushed them in one at the time and instaling the rod pin right after the piston was inserted.
I will call on Monday see if they have just the new piston Assy.
I'm not sure what you paid for the rebuild kit, and now add more parts to that, but maybe a replacement pump would be a more economical option? Not to mention there are much higher CFM pumps available.
Here's what I did: Aux air pump system replacement (http://www.foreforums.com/index.php?topic=44535)
what did the whole project cost
and yes how many days worth of work?
My project total was more time and cost, but fourdayoff just did the pump swap. The Air Zenith pump runs $369 on Amazon. It pulls 35 amps, about 7 more than the Thomas. The circuit breaker for the Thomas pump is a 40a. I used the same wiring and left it on that circuit breaker. No issues.

On a new note .
I called Zoro and explained what happened and they will warranty me a new part. Great customer service from Zoro.
As Keith stated I did just replace the Thomas compressor, I was able to modify the original muffler to use also and I'm very happy with it. I was going to go the route you did but just could not justify the cost then still have a 20yr old compressor. Jim.
