today a buddy of mine and i took the hydraulic motor and OLA out of the 99 coach i recently purchased. it was leaking somewhere, lost about 1-2 quarts in the 400 mile drive home. i always need a small helper to get in tight places. glen is a canadian farmer/mechanic and a great neighbor who jumps in and helps me when i need it. and he is small....ha
i assumed it would be leaking at the same seal on the OLA that richards was. but...it was not. we took it off the mounting bracket and cleaned it all up with brake cleaner and ran the engine for 10 minutes or so. no leak at first but after it warmed up it was leaking steadily out of the OLA hydraulic fitting.
we did things a little differently than we did when i was at richards. today we took the hose off the OLA and took out the entire fitting. you cant get a wrench on it and you can see where they tapped it on with a punch. we did the same thing to take it off. low and behold, there was no o ring on it like it should have had. we plugged the hole with a rag, put a bucket under it and put my kiddie plastic play pool i used to catch fluids when working on things under it.
off to napa we went and for 13 bucks we had an entirely new fitting. put it on and then took the big steel motor bracket loose, took the fan out and i pressure washed it, and we cleaned the engine compartment and underneath as it had been leaking for some time.
we are letting it dry and will put it back together on monday, but we are sure that is where the leak was.
i will update on monday after finishing it
