How much work R&R power steering gasket(s) 1994

[raxley]

The power steering is leaking much more fluid lately. How much work is there to replace the gaskets or seals to fix the leak?
Is this the time to also rebuild or replace the vanes that enable the vacuum to develop?
Is this a couple hours for the job?
I need to fix this myself, money is tight!

Normally it is the seal between the PS pump and the vacuum pump that leaks. The kit you picture does not have those parts, so exactly what is leaking? If it is the seal you need either a Cummins PN 254089742 which costs the least, an after market kit '91.5-'02, 5.9L Dodge Cummins Vacuum Pump Seal Kit (genosgarage.com) or if you don't have the tools or know-how the most expensive option
'91.5-'95 Dodge Cummins Vacuum Pump Reseal Kit (genosgarage.com).

The vanes seem to never wear out. I bought a set of new ones several years ago and compared them to the ones that had about a million miles on them. The package of new ones is in storage.

Take the two out as an assy and you can probably do it in a couple hours if the work space isn't freezing.

I'll buy the $60 kit.
I noticed that there is also a drip at where the steering wheel shaft goes into the steering box. It looks like it's leaking around the shaft. Do you know what it takes and a basic idea of how much work this is?
Thanks again, TDR really is as important as the factory repair manual!

I'm pretty sure the procedure is in the FSM, I've never had that problem. Removing the gear box is a relatively simple job. Opening it up, I don't know.

I removed the 3 piece pump (vacuum, power steering, and reservoir (with the cap for power steering fluid) but I still have leaks. I don't know where one leak comes from, it's above the pump assembly. I'm wondering is maybe the p7100 is leaking (unless there is s power steering lline up there) and then I also have a leak where the universal joint on the steering shaft goes into the steering gearbox.
what things should I be looking for if the p7100 is leaking, and can anybody give me the rough guidelines of fixing the leak from the steering gearbox?

 

[GAmes]

The oil supply line for the vacuum pump is connected to a T fitting. The line going up from that fitting goes to the injection pump. Those lines or fittings have been known to spring a leak. Also, if you shine a light between the P-pump and the block you will see a rod that sticks up out of the pump about a half inch. The seal around that rods gets worn and it will leak too. The one on mine is the only repair that has ever been done to my pump.

Tappet cover?

Forgot that one. Much more likely than a line or the rod.

The leaking fluid looks the same as the power steering. When I disconnected that oil supply line to the vacuum (last Saturday, when I replaced the seals), its dark oil.

Forgot that one. Much more likely than a line or the rod.

I looked at the pipe sticking 1/2" out of the back of the p7100. No leaks there although it's pretty damp with some liquid. I've discovered that there are two leaks. One is fuel coming down above my 3 piece vacuum/steering pump reservoir. I can't see where it's coming from, but it's not from the 1/2" pipe. I can tell because the power steering fluid is slippery and the fuel isn't, although they look the same. Any ideas for the fuel leak?
The other leak is coming from the steering box, around where the u-joint from the steering shaft goes into the box

It isn't a pipe, it is a rod. At the bottom end of that rod is the fuel shutoff lever. Any leak there would be engine oil. The fuel return line out of the OFV crosses above the pump and goes behind the fuel filter where it is connected to a rubber hose going to the tank. That little section of rubber hose needs to be replaced every now and then.

One way to locate a leak is to sprinkle talcum powder over the area. A salt shaker full of flour could work too.
