Ford 7710

I have to replace the pro seal on my ford 7710 how hard is this to do? Any tips?

NOt hard.. Park the front end where its 4 inches lower than the rear so you dont lose fluid. There are two seals... one is a regular seal...d9nn710bc $32.74.. the other is an oring that goes between the dual speed removable pto shaft and the housing, 9823571 $3.40. On the dual speed ptos there are some thrust washers that can fall down, so you need to keep a false shaft in the pto hole to hold those in place while your changing the seal. Just an overview from my travels.

So do I need a dummy shaft for the oring or the seal? Do I need to replace both? It looks like its leaking right where the shaft goes in.

That would probably be the oring if it leaks right at the shaft itself. Anytime you pop out the shaft, I recommend a dummy which is no more than a screw driver set into the hole, through the two gears... so that I dont end up bumping the gears and letting the washer drop down... Then replace the oring into the little groove with a dab of grease to hold in in place, then re insert the original shaft and pinch clip. (remove the dummy screwdriver first) In most cases I found it still needed the bearing housing pulled and the seal replaced as a secondary step.. again, using something to place through the two gears so the thrust washers dont fall if you bump the gears.. a dub of heavy grease on the washers will help hold them for final assembly.

When replacing the oring does the pro need be engaged or disengaged

If the washer drops is there a way to get it out?
