HI Ive got a bobcat 443 that i am working on but does anybody know how the thing turns? i know it locks up the one side then the other side turns but where do the levers connect to? and there is a kubota D570 and i just wanted to know if the diesel pump would pack up after standing for about 3 years ,like what happened to our truck it stood for about the same time but when we started it kept on revving up so will it happen to the bobcat?I really hope not!!! thanks

Welcome to the forum. It is unlikely that just sitting would damage a pump. Getting water in the fuel while sitting then sucking it into the pump when you start it can though.
A skidsteer drive is basically 2 separate hydrostatic systems.Both can run at a speed of 0 mph to 6 mph or anywhere in between, buy driving the wheels on one side of the machine slower then the other (or in the oposite direction) the machine turns.
Search skidsteer transmision or hydrostat drive and you should get more info.

Hi! I Know how it works but there are two leavers (steering} that are not connected anywhere!! and the motors that drive it are also not connected only a pipe from the two to the hydraulic tank thanks

The levers will have to attach to the pump, one lever per pump. More the lever one way oil will flow in one direction, move it the other and it will reverse. So the linkages to the pumps swash plates must be missing. You then will have to have two hoses from each pump to the motors, the ones you mention now sound like case drain lines as they go back to the tank.
The best investment you can make now is a parts manual, it will show you what goes where.
I can't see the machine sitting causing issues, as Ken said, water is the biggest issue, bit if it was dry i see no problems.

hi ,where do the levers go to on the motor? is it the pump or motor? and what is a swash plate? is it the brake disk?and the motors that drive it have a thin pipe on each of them.. and I am only going to fit ONE hydraulic pump so how do the motors get connected? please help me!!!

Thats why you need a parts manual, if you post some pictures we can help, but I have never had a 443 so I'm not a expert on them either. A manual will pay for itself many times over.

If its hydrostatic drive the levers will go the the drive pumps, not the motors.
Pictures would be needed for more guidance, a manual is needed if its missing parts

hi what if its not hydrostatic drive ? thanks
