Differential Side Bearing Preload And Gear Backlash
Differential bearing preload and gear backlash is achieved with selective shims (2) (4) located between the differential bearing cups and differential housing. Shim thickness is determined using Dummy Bearings D-348 and Dummy Shims 8107 in place of the differential side bearings and preload shims.
Before measuring differential bearing preload and gear backlash, pinion gear depth must be established and pinion gear prepared installation. Pinion gear depth is essential to establishing gear backlash and tooth contact patterns.
