Loosing hydraulic oil

[tomstu]

I recently brought my bobcat 853h in a shop to have the axle bearings and chaincase bearings changed. They also replaced hydraulic oil filters. They put 10 gallons of hydraulic oil in hydraulic tank. When I went to pick it up it was growling. Checked tank. Nothing on lipstick. Put in about 4 gallons. Got home and started up to unload and was growling again. No oil on lipstick. Put in 3 gallons. Very little oil leaking out. Ran about 10 minutes started growling again and bucket would not lift. No oil again. Where is this oil going? If I have a blown shaft seal on drive motor , can oil be draining into gearcase? every thing was working fine until I brought it to shop. Any possibilitythey couldhave hooked hoses up wrong on reassembly?

chaincase?

Ask the "Shop" you paid to have it fixed and filled.
If not on left or right side (remove the lower side covers) then its filled up the Center case..Chain Case.

If the motor carrier seal goes bad the oil goes into the chain case.

If you remove the chain case oil plug on the front of the machine and oil pours out then that is most likely the problem.
