    Bobcat 763 wiring + boss bypass

    You'll have to look up the different sensor part numbers in the parts catalog. The manual should show the serial number breaks for the non boss style in the electrical schematics section. I've considered the same thing, but I don't have that much time on my hands.

    Bobcat 853 bearings and seals

    I didn't see any numbers on it at all, but with the OD you should be able to find it. Also couldn't find an old seal. Must have taken out the trash already. Here is where I got mine from- https://stores.allskidsteers.com/axle-cup-bearing-for-bobcat-skid-steers-large-frame-replaces-oem-1321607/

    853h bobcat drive sprockets

    If it runs, put the box end of the wrench on the bolt, start it, and use the drive motors to break the bolt loose. I have a four foot pipe wrench that will grab the hub for the back axles. They are supposed to have loctite on them, once they are cracked loose you can spin them out with your...

    Bobcat 853 noise when turning

    Could be the gear reduction bearings. You'll know when you get the center cover off. The primary sprocket the front and rear chains are attached to should have no slop in it. If you can grab it and wobble it, the bearings are gone. I ordered all of them from allskidsteers.com. It is not an...

    853 gear reduction mayhem

    Also couldn’t find a muffler, and adapted 7350311 to fit. The right hole and exhaust tip lined up perfectly. Had to clearance the door and radiator cover a bit. It’s larger pipe, so I welded up a coupler to the factory flex pipe. It’s a lot quieter than the rotten one with no tailpipe I was running.

    853 gear reduction mayhem

    The chaincase has an open hole to the gear reduction and is lubricated with chain case oil. I use old hydraulic fluid in my chaincase, which I have in surplus due to these shenanigans. The two holes in the coupler shaft go to the interior of the gear coupler, they are drilled at an inward...

    853 gear reduction mayhem

    Can blow air through the return and hydraulic pressure is normal. Motors have fresh seals and will run on air, and hold air pressure even. (I was gentle, low pressure only). I thought maybe there was an internal leak in the motors.
