Power steering pump

[trooper632]

My M998's power steering pump is toast I believe. Its noisy and it overflows out of the cap, gets foamy. its a 1987 model but it has a 6.5 in it. Are the pumps just plain GM pump or are they special for the military, I think I need to replace it, didn't know if I could get it at NAPA before I pull it off, Thanks

I bought an a.c. Delco ps pump and am in the middle of It. The shaft isn't as long as the original pump, but besides that.

Noisy and foam is air in the system.....

Air in the system. Bleed the ps system. It's not in the tm, but Google will pull up the procedure.

HMMWV PS pump

It's easy to bleed the system. Put the front end up on jackstands, make sure the reservoir is full and turn the steering from lock to lock and hold it at each end for a few seconds. Make sure the reservoir stays full or you'll just be sucking more air into the system. You may have to do this 10 or 20 times to get all the air out.

The pumps are just Saginaw pumps off of Chevies. Pick one up at a wrecking yard or bite the bullet and drop $20 off at O'Reillys.

Bled the ps pump, and working as it should. Thanks for the help.
