How is pinion backlash measured?
How is pinion backlash measured?
Turn the adjustment knob on the side of the dial indicator gauge until the gauge needle points to the “0” setting. Rock the ring gear back and forth with your hand while monitoring the gauge needle. The distance indicated on the gauge is the gear backlash.
What is pinion backlash?
Backlash is the play—or how much play there is between your ring and pinion gears. This play becomes important when the loading and unloading of the gear occurs (acceleration/deceleration). Once the pinion depth is properly set, the backlash needs to be adjusted and set.
How much backlash does a Dana 35 have?

Why backlash is provided in gears?
Backlash refers to the angle that the output shaft of a gearhead can rotate without the input shaft moving. Backlash arises due to tolerance in manufacturing; the gear teeth need some play to avoid jamming when they mesh. Backlash typically increases with the number of gear stages. …
What should the front suspension look like on a 1980 Corvette?
The two rear lower control arm attachments must also be securely welded to the frame. Your completed front suspension should look like this unit, which is installed on a 1980 Corvette.

What are the features of a new Corvette?
To top it all off, every new Corvette gets a gently buffing with lambswool-type polishing pads. Anti-corrosion measures. An extensive program has been designed to help the new Corvette withstand the elements even better than any previous model.

What should the back lash be for pinion gear?
12. Once the pinion gear is installed, position ring gear and carrier into housing to check backlash. Motive Gear and Motive Gear Performance ring gear and pinions are developed to be run at .008″ to .012″ back-lash for street gear sets.

The anti-roll bar has not been installed and is the only missing part in this photo. The upper and lower control arms secure the coil spring.
How does backlash affect the pinion position Shim?
(2) Increasing backlash moves the ring gear away from the pinion. Drive pattern moves slightly higher and toward the heel. Coast pattern moves higher and towards the heel. (3) Thicker pinion position shim with the backlash constant moves the pinion closer to the ring gear.
