Hahaha, well good thing I'm nothing near a "professional" so I don't feel too bad that I messed it up. I do wish this thing had something more in the way of gauges for troubleshooting though, see what the pressures are running at would probably help. Hopefully when I get it back together it's no...

Well, I think I figured it out. The short answer is that due to buying it as a box of parts, and not having the experience of taking it apart myself, I messed something up when I put it back together. I ordered my parts and put the pump back together using the diagram for the pump as provided by...

It's air cooled, so no coolant to get in there... Tazza, good call, that's my plan of attack. I'm almost positive it has to be leaking in through there and I must've blown that input shaft seal somehow. Why it blew is a different story though, I have no idea there yet. Of course now I get to go...

Nope, no fuel smell in the engine oil. And it filled up so quick the 2nd time, I didn't see how it possibly could've dumped fuel in that quick. The only other thing I'm thinking is that maybe the oil level being high filled up some other areas in the engine, and it drained back down into the...

So I just got my old Bobcat 520 running last weekend. Thanks to the tips from Tazza, I got the hydrostatic transmission reassembled and everything put back together. Filled it with lots of oil, fired it up and everything worked great for about 1.5 hours! Then, the engine started billowing lots...

Thanks Tazza, I'll give it a go and see how it runs. I guess I can always pull it apart again and replace them later! Looking forward to some quality time over the sand paper with the big heavy pieces getting ride of the grooves...

Thought I'd jump on an old thread to try and get some info on piston end play. I have an old 520 I'm working on that has as TA1515 pump. The piston shoes seem relatively loose. My best guess at measuring it with a set of calipers is about .010" of play on the worst ones. The manual says no more...
