OK, just looked at the floor jack. It's rated for 5000 pounds, I'll see if it can lift the truck using the crossmember.

EDIT: OK, the jack worked fine, I turned it back and forth, added fluid and so on. The steering turns easily now with the wheels on the ground, however the fluid is pretty "foamy" still, and there is a tiny bit of roughness at the left end of the travel of the steering wheel.


Also, will an oil feed line to the vac pump off of a '99 Cummins fit my '92 ?

 

No one knows if a vacuum pump oil line of a 99 Cummins 24 valve will fit my 1992 ? The guy selling it on the bay is unwilling to answer such questions...

 

i dont know if the 24v one will work but if you deide to have one made you can go to fluid connectors in portland

 

Good to know, thanks.

Though the steering isn't totally smoothed out yet, I'm not losing PS fluid any more. There's still oil dripping off the bottom of the two pumps, though. I cleaned them with a dry rag, ran the engine some more, looks to be coming from the vac pump somewhere. So I guess I get to figure out how to reseal that now, too. Looks like I need, what, an impact wrench or gear puller to get the thing apart ?

 

Still dripping oil off of that vacuum pump. I started it up yesterday while working on some other of this truck's endless problems, and noticed that the top of the vac pump collects little puddles of oil the minute the motor is turned on. Examined it pretty carefully, and there isn't any leak above the vac pump, this is a result of some blown seal in there somewhere. But how would it get on TOP ?!?

I have the seal kit from Cummins, now I'm in the process of making some time to deal with it this week.

From what I've read, you need an impact wrench to pull the gear out of the vacuum pump ? Neither Schmucks nor Autozone nor NAPA rents those out any more.

Is there an alternate way to get the vacuum pump apart besides using an impact wrench ?

Then again, there are those used pumps that pop up on Ebay...

 

You're thinking of the old style vacuum pump. Yours needs no special tools.

 

How do you pull the gear out ?

 

Why would you want to pull the gear? There's no seal at the front, only at the back.

 

Oh, the seal kit comes with several large seals, not just the small O-ring that goes in between the PS and vac pumps. Guess this kit is "universal" for both styles of vac pumps then ?

How about pulling that O-ring ? Do you just yank it out with a pair of vise grips or is it a more delicate operation ?

TIA.

All you have to do to replace the o-ring is pull the two halves of the pump apart, the shaft and rotor stay in the front half. A properly sized socket or piece of pipe is needed to drive the old seal out of the back end of the pump, and to drive the fresh seal in.

 

Cool, thanks for the link. I noticed mine is missing this bracket. Wonder if it cracked the housing like the one pictured and this would account for the oil on top of the pump, or if the seal could do that ?

No idea where to get a bracket, Cummins probably sells them for $80. Maybe I'll adapt one from Lowes or something...
