Maintenance

Getting a hydraulic leak in the Pinon Gear Housing air vent.  Steering works well but dumping fluid out.

If there is oil coming out of your circle drive housing breather, check your oil level.  If it is over capacity, you may have a leak from your drive motor shaft seal adding hydraulic oil into the circle drive gear housing.  Hope this helps..

The reason that my reply is about the circle gear drive housing is because I do not know of any 12 series motorgrader with awd.
