What happens if pinion preload was set incorrectly?
What happens if pinion preload was set incorrectly?
If the preload is set too tight the pinion bearings will wipe out, fail, lock up and cause a catastrophe ring and pinion gears. If the preload is set too loose the rear end will whine, the pinion gear will attempt to walk up the ring gear causing abnormal gear wear and eventual fail.
What happens when there is too much pinion pre load?
Too much force will collapse the crush sleeve and apply too much pressure to the pinion bearings (blue) against the pinion race (yellow), resulting in too much pinion pre-load. Too much pinion pre-load cannot be undone.
Do you need to torque your preload and backlash?
To install your ring and pinion gears and/or differential correctly, it is critical to torque your bolts and set your preload and backlash correctly. The following table contains the proper specifications for all popular axles. NEW! – Need help with your ring and pinion gear set up?
How do you set pinion bearing preload on a differential?
To set pinion bearing preload, use a holding tool to keep the pinion gear stationary. Then a breaker bar or torque wrench can be used to tighten the pinion nut. CASE BEARING PRELOAD.- The case bearing preload is the amount of force pushing the differential case bearings together. As with pinion bearing preload, it is critical.
What is the correct way to set backlash?
Different backlash pattern markings—correct and incorrect. Setting backlash is done using a dial indicator to measure the free movement of the ring gear. A typical set of gears comes with a marking compound. This compound is used to show what the pattern actually is on the ring gear while adjusting the backlash.
When to adjust backlash for ring and pinion?
If the backlash is too wide, adjust the carrier toward the pinion. When adjusting the backlash, a rule of thumb is 10 thousandths of carrier shim adjustment will result in around 7 thou of backlash adjustment. Rock the carrier back and forth until little to no free play is evident.
