Great site .Been lurking for a while and finally decided to join.Been around heavy equipment my whole life since my dads a 40 year operator. I dont know a lot about wrenching on these machines but Id like to learn.
Heres the problem. We bought a 1989 gehl sl 6625 with 2100hrs on it last year and ran it for about 50 hrs.Ran great with just a little creep. We figured we'd pull routine maintance on it over winter so I bought the shop/parts/engine manuals on ebay to guide us through it. We changed some hoses to the drive motors,changed planitary oil,chain case oil ,tightened chains, changed hydo and all the filters. We took it outside of the shop to clear some snow and everything was fine.
While we were in fixing things mode my dad wanted to take the creep out of it. He tried to tweak the boost control servos per the manual. Now it will only go forward and backward on the ground. With all the wheels off the ground it turns and does everything fine. We checked the hose routing and its good. I tried to recenter the servos with no improvement. I had a mechanic buddy that works on gehls "a little" set the servos and still nothing.
Any ideas? Sorry for the long post but I wanted to give as much info as possible. Thanks in advance.
