  • Differential Pinion Pre-Load Adjustment

    Pinion pre-load is the force (pressure) between the pinion bearings (blue) and the pinion bearing's race (yellow) As the pinion nut is tightened it forces the yoke against a "crush sleeve" (red) that is designed to "control" collapse under force.

  • what is a crush sleeve? how does it work ,

    The crush sleeve as in its name is to be crushed upon final differential assembly and keeps the bearings pressure consistent in the bearing cups NOW the Nut at the time of assembly will take 100-180 FT Lbs (depending on the size of the sleeve ) to crush a crush sleeve to the point at which the bearings are seated into the bearing cups/rac.

    Aug 03, &#; So by the time you 'crush' the bearings in place, the egg-shaped hole will pinch the shaft So your tendency is the bore the mains bigger and loose the 'crush' to loosen the bearings But this is wrong! If you loose the bearing crush, then the bearing will spin in the mains How much crush is required? Well, depends on how big the bearings are.
