Put my drill back to new.
My part's arrived promptly, and it was super easy to fix my IR drill. I'm grateful for replacement parts to be available. So I bought double of what I needed for the wear part's. Now I just need to find more air tools to repair. Hahaha

Air impact wrench would not stop
Chad - August 4, 2022

Tool Type
Ratchet Wrench
Difficulty
Medium
Time
15-30 minutes
Tools Used
Socket set, Breaker bar, angled pick, air tool oil, blue loctite
Parts Used
Ingersoll Rand 231G. Remove trigger. Remove air inlet with socket & breaker bar. Remove plate and valve spring. Dump out air valve. Force angled pick down between valve seat and body of the tool, pry out seat. (This is difficult and will take several tries.) The valve seat has a wide-open side and a slightly "fatter" side; the open side goes in towards the motor, fatter side towards the air inlet. Lube it with a bit of air tool oil and slip it in; using the biggest socket that will fit down the hole and an extension, press the seat all the way down to the bottom. Drop the air valve in, stem first. Drop the spring in, narrow end down. Reinstall the spring and plate; reinstall the inlet with blue loctite. Reinstall the trigger.

Removed old parts to find out what was broken. Ordered parts , ordering parts was very easy and fast shipping. It took two times to get the parts back in the correct way. Successful the second time and wrench works great.

replaced valve seal for IngersolRand 231H impact wrench

Difficulty

Time
30-60 minutes
Tools Used
Socket set, 15\\
Parts Used
Watched a few vids on how to get to this seal - none prepared me for the red Loctite IR used on the threads. After padding out an under-table vice to securely hold the impacter, it took a pretty good tug with a 15" breaker bar to break loose the nut that holds the air fitting.
Once committed to lean on that nut (the 6 point socket left it's mark on the flats), out comes the spring, the valve piece and then the old seal, which pulled straight out with a hooked tool. New seal pushed in easily with a deep well socket. The valve had sharp edges, so softened any felt edges/corners with a fine file before reinstalling. Cleaned and lubed the hammer mechanism, bearings, and the vanes/pump while at it, so this impacter is good as new again

Air ratchet would run without pressing the throttle
William - February 27, 2022
Tool Type
Ratchet Wrench
Difficulty
Medium
Time
Less than 15 minutes
Tools Used
Pliers, Roller pin punches
1. Removed roller pins with small punch.
2. Slide out the bottom plastic housing of the ratchet
3. Remove air inlet
4. Remove spring and throttle valve
5. Remove air inlet quantity adjustment knob while making sure not to lose the metal pin
6. The throttle valve seal must be installed exactly the same way it’s removed or it will leak.
7. Pull out old seal with pick set and install new one.
8. Reverse of steps.
9. After everything is back together the throttle should be able to be pressed and it should spring back. If it doesn’t the throttle valve seat is either installed wrong or the spring is wrong. Nothing should need to be forced too much into place except the roller pins.
10. When installing the roller pins for the throttle switch and air adjustment knob. Make sure the knob is pointing in the red range marked on the plastic housing of the ratchet. If it’s pointing outside that range and the pin is hammered in, it will damage the knob.
