Top cover gasket/seal kit

[Harry in Ky]

This isn't exactly a Ford question, it's just that the subject matter is on a Ford 7610 tractor. Having done a number of throttle shaft seal replacements on CAV DPA pumps, I;m pretty familiar with the process and even a few tricks to make it a little easier.

Never having done same on a DPS model, I'm wondering if a "kit" is available or is it all one piece at a time? It appears to be a little more involved than the DPA so I'm hoping someone has been there before and may have something to offer. What I'm working on looks pretty similar to this. Leaks seem to be mainly throttle/shutoff shafts and the O ring (27).

The DPS is NOTHING like the DPA pumps are top cover wise. The scroll plate fuel control plunger is a challenge on the work bench and test stand and I would NOT attempt putting the cover back on with the pump on engine. The later DP 200 series are worse yet. I won't do "patch jobs" on either DPA or DPS pumps anymore, my experience has been when ANY leak shows up it's best to reseal the complete assembly. Too many times in the past after the patch job is done other leaks show up shortly after and pump needs to come off anyway.

Okay, point taken. Can you give me a ball park guess as to what you would charge to go through this pump If I pull it off and send it to you? I don't have the pump number. I had planned to write it down when I was there but didn't get to it.

The last Ford DPS pump I did was 500/550 if I recall, parts and labor. I can't get to it until after first week of June.

Okay, thanks.

So if he decides to go with the repair, what is the timing spec we're looking for on the flywheel for the early DPS models? It's not a lock timed pump. 24 degrees? 27 degrees?

I have no idea. If the pump drive is KEYED or PINNED like older pumps no crankshaft timing should be needed. I don't have any manuals on the later tractors.
