Skidsteer 753 question

[financer83rs]

I have a bobcat that the rear left wheel will not drive. The other three all drive like normal however that left rear one won't. The bucket lifts tilts and operates normally. Can anyone tell me where i should look for a solution? Could low hydraulic fluid cause this? Is there a sheer pin or something similar on each drive axle? Any insight would be appreciated! Thanks.

Raise the left rear wheel and turn it by hand. If you can rotate it all the way around, you probably have a broken drive chain. You will need to drain the chain case (remove the pipe plug on the outside front center of the hull). The chain case should have 8-9 gallons of oil. Next you will have to raise the cab and remove the rear chain case cover in the center of the hull. That will allow you to inspect the sprockets and chains.

Thanks TriHonu - I raised the left side of the skidsteer and found that both the left front and rear have little to no movement. The left rear wheel is like an anchor. Three wheels trying to operate as directed and the one standing still ruining all the fun. Do you have any other suggestions? Your input is greatly appreciated!

Like TriHonu said the drive chain for that axle must be broken for the front wheel to rotate and the rear not. If the left rear is seized and won't rotate then the axle bearings are likely what caused the chain to break. Like he said you have to open up the top of the chaincase and have a look.
