What are the teeth on a pinion gear?
The tooth surface on the ring and pinion gears is only moderately shiny. The machining striations on the drive surface of the ring gear teeth are still visible (on the actual gear set, if not in the attached picture). The face or edge of the pinion gear teeth is still squared off.
How do you install pinion on a differential ring?
Install the pinion bearing on the pinion gear and don’t forget any applicable pinion shims. Install the pinion gear temporarily with the old crush sleeve (tap on the side of the crush sleeve while it is on the pinion gear to make it “longer” or “uncrushed”). Put some motor oil or gear oil on the bearings.
What causes a pinion gear tooth to burn?
The face or edge of the pinion gear teeth is worn to the point of being sharp. Burning like this is caused by lubrication failure. There was not enough oil in the differential, or the differential was not properly set up, became too hot, and the oil broke down. Click Here for a larger image.
What causes the ring and pinion gears to fail?
A visual inspection of the failed or damaged ring and pinion gears and/or bearings will usually indicate the cause of most failures. The tooth surface on the ring and pinion gears is only moderately shiny.
