943 Bucking bronco problem

[professorbolin]

I have a 943 Bobcat with a 4.236 Perkins Diesel engine. The alternator belt came loose on the previous owner and the water pump did not spin causing the engine to over heat. The engine was toast when I bought the bobcat. At the time the engine went out everything was working fine. We pulled the engine, had it machine shop re manufactured and re installed the engine. the engine runs fine, the bucket raises, lowers, and tilts as it should. touch the levers a hair forward or backwards and the machine wants to buck like a bucking bronco. once you get it rolling it rolls fine until you stop and attempt to go another direction. We changed all filters and drained and replaced all Hydraulic fluids. all hoses are on the correct spot. I am puzzled. HELP!

is there any chance you installed the motor in a wrong position, perhaps throwing off the balance?

No the engine is in the same exact spot as it was when it came from the factory. I believe it is in the Hydraulic system some where. Maybe from sitting for over a year a valve maybe stuck or some other problem. I hate taking it to a bobcat dealer as they charge 5 to 8 times more than a fair price.

Check the linkages between the steering levers and pump, if there is any play in here, it can cause it to buck around.
Even after years of sitting, it should not buck around when you try and drive it.
