Within a differential are two gears, a ring gear and a pinion gear. When the vehicle's driveshaft turns, it rotates the pinion gear. The pinion gear intermeshes with and turns the ring gear. The ring gear transfers the power through the axle shafts to the tires. The amount of play between the ring and pinion gears is referred to as gear backlash.

Use a dial indicator to check ring gear backlash in a differential's ring and pinion gear set. They're also used to measure distances and to check flat surfaces like the engine's flywheel for runout. They're used to check end play measurements like crankshaft end play and to measure back and forth movement in different areas of an automobile ...

the job being done. If you're changing the ring and pinion or the pinion bearings, remove the pinion nut with an air gun while holding the yoke, or use a long breaker bar and brace the yoke (bolt it to a long board) so that it can't move. Knock the pinion gear out to the rear with a brass punch taking care not to damage the threads.

To measure ring and pinion backlash, position a dial indicator stem on one of the ring gear teeth. Then, while holding the pinion gear STATIONARY, wiggle the ring gear back and forth. Indicator needle movement will equal gear backlash. Compare your measurements to the manufacturer's specifications and adjust as needed. Backlash adjustment can ...

on the clearance between the tips of the pinion teeth and the roots of the gear teeth. Do not measure the root clearance between the tips of the gear teeth and the roots of the pinion teeth as this could give erroneous results. If the teeth of the new pinion will mate with the worn flanks of the existing gear, proceed to Step 6.3.1.1, otherwise

Mar 20, 2013· When speaking of gears, backlash is the amount of clearance between mated gear teeth. Some backlash, aka "play", must be adjusted into a gearset to keep it from getting bound up, especially for a gearset like a rear differential that works in both directions, i.e. forward and reverse, as well as to account for thermal expansion/contraction, and to allow lubricants access to the surfaces.

So I think that a ring gear shim would do the same thing and I'm going to leave out the shim and live with the lash as it is. I also stoped at NAPA on the way home and purchased some persian blue. I dabbed some on three teeth with my finger and rotated the ring gear thru the pinion gear by turning the drive shaft. Here is the pattern.
