P/S pump rebuild kit #

On the Coronet I have a .94 Saginaw pump with the oval fill tube. There's a leak at the pressure hose fitting.
Before opening up the pump, can the pressure hose fitting be removed and the O ring replaced without tearing into the pump? For those of you that have the '69 FSM, I'm looking at page 19-29, Fig. 20.

If not, I've been researching seal kits and think I have it narrowed down to either Gates #351170 or Edelman #7895. Can't be sure because the reference is by engine type not the make (Saginaw, Federal, TRW)

The other part numbers that seem to cross-reference are Gates 351090 and Edelman 7918.

Has anyone that has rebuilt this pump kept the rebuild kit #?

Rockauto is good for sourcing parts and p/n 's

I have an account at RA. They list 3 Gates p/n's for the Coronet. Cross referencing to the Gates site, they reference 1 of the p/n to GM, the other 2 for every Mopar engine from a 225 up to a 440. Can't determine if it's a 1.06 or the .94.

Not sure what your looking at, but the RA site does call out what pump. Look at 69 Coronet 318, and PS seal kits. 7918 is called out as saginaw

Reviving this thread after almost three years. The pump has had a continual slow leak from the pump housing/reservoir. I bought a rebuild kit from Rich Ehrenberg on Ebay and used some time off this week to finally address the leak. The FSM and YouTube gives anyone all the information they need to rebuild a Saginaw pump so I'm not going to go into the gory details. Upon disassembly I found the reason for the weeping: rust had formed around the ridge of the reservoir, eventually working into the O-ring channel and pitting the O ring.





After removing the center shaft I think I found a bigger problem. The outside face of the cam lobes and the inside bore both have scoring marks. Can someone tell me if these surfaces are supposed to be smooth?

I went ahead and cleaned and reassembled the pump with all new O rings and new shaft seal. There's not much to these pumps and once cleaned up they go together pretty quickly. Reinstalling the shaft back into the bushing requires a little persuasion; one tip I picked up on YouTube to protect the shaft was to place a penny on top along with a deep walled socket and gently hammer the socket until the shaft seats in the bottom of the bore.


Another thing to remember is that the shaft has a Woodruff key to align with the pulley and the key will fall out under duress. The key fell out while initially removing the shaft from the pump and I spent several frantic minutes searching the garage floor before finding it. Better to remove it before starting disassembly.
The FSM and YouTube videos make it very clear but I'll mention it anyway; when dropping the vanes back into the rotor slots; the rounded side faces outward towards the cam ring.

The hardest part of the assembly is installing the cover plate and retainer ring. It's a fairly stout spring underneath the cover plate and it requires either a set of strong thumbs or a large C clamp to push the cover down against the force of the spring while trying to engage the ring in the channel. It took me about 20 minutes. Eventually I got the ring started by pushing down on one end of the cover and starting the ring, then very slowly working the ring around the bore while rotating the pressure on the cover. Once the ring is fully seated the cover will snap back into correct position. The pump is done, all that's left is painting the reservoir.
