case 1816 bucking while turning

[sectlandscaping]

I just picked up a case 1816 off ebay. The bucket is smooth but the drive hydraulics are jumpy when turning left. It bucks pretty bad, enough to not be safe.

When I looked at the boxes the controls are connected too. One will move side to side but theres a spring in between them. So is this supposed to have play in it?

Other then that any ideas what this could be? At low speeds it doesnt do it or with light turns.

I'm assuming the boxes you speak of, are the hydraulic control valves for the drive motors. If the side that is loose is the side that gets jerky on the turns, I would guess once it starts, being loose only compounds the movement. Your hand on the control is moving more back and forth than you realize.

I'd see what could be done to snug it up.

After looking at this there supposed to flex back and forth. When you push the brake switch the control valves move to put tension on belts.

The fluid is clear and full. The filter looks newer.

Dealer said it could be a worn bearing but there 60 miles away.

The controls could use a adjustment. It creeps when it should be in neutral. Not sure if that will cause the problem I'm having when turning?

Dad had one years ago, but I did not help him work on it much. One problem I do know was with the main drive belt slipping. A buddy of mine bought one about 10 years ago,and had some movement problems with his. I suggested he check the main drive belt. It was a little loose. He snugged it, and eliminated the problem.

Both were sold, so I'm not real up on them, other than that one particular item that seemed to be a problem.

I have a Bobcat 450, and depending on the surface you turn on, it will get rather jerky at times. Proper air pressure in the tires can be a factor too. If one is low, and allows the sidewall to roll under some may case something like that.
