I agree with Craigy2; it does sound like you have air in the drive/drive control circuit. The pop could be burping air in.
Getting stronger with use certainly sounds like flushing air from the motor circuit.
I can think of two main ways to get air in
All the best,
Peter

- Could you have gotten air in during a filter change?
- Could there be a loose connection anywhere on the vaccum side of the intake to the tram pump?
All the best,

finally went and retrieved my pt this past weekend and disassembled the forward/reverse control valve , for lack of better description the floating shuttle/plug was stuck in the bore and not fully traveling the length of the bore as designed to enable 100% forward or 100% reverse which is why it was stuck in reverse or would creep, at least it was a cheap fix , just for reference a bx24 bota will not retrieve a pt425 , but a small dozer will though
That is what was the matter with mine, I tried to explain it as best as I could in post # 6 but I'm not good at explaining things I guess. I put a new plunger in mine to fix it, didn't cost much. If you just sprayed wd 40 to get it to work right it may stick again soon but at least you know what is the matter with it and can get it going without much down time. Hate that it took so long to get it going though.

do you still have part numbers? for the plungers and supplier? the valve is ''hanging up'' again after about an hour of use so I feel it is time to just replace parts
Thanks in advance
I don't remember much about it, it has been so long ago. Call Terry at power trac and describe what is going on and he can help you probably. Sorry I couldn't remember more about it.
