My 743 has a problem anytime that the aux hydraulics are dead headed against relief pressure or the tilt is dead headed all the way back or dump the boom will raise on its on. Anybody got any ideals ?
Is there anything in the drive motor its self that cause leakage into the chain case, This thing will empty the hyd. tank in about 15 minutes of running/working it.
I have got a 773 that is putting hyd oil into the chain case. Is there any thing other than the seals between the drive motor and the reduction box that can cause this ?
