If the assembly does happen to be positioned off-kilter and becomes stuck must be removed, it can be pulled from the front, or carefully tapped out from the rear. <br/><br/> To remove the assembly from the FRONT: Clamp the hub into a bench vice, spindle facing up. If a vice is not available, clamp adjustable or locking pliers onto the circumference of the hub. If the pliers utilize teeth or grooves, some cosmetic damage is likely to occur to the hub. <br/><br/> Install an M8-1.25 bolt into the spindle. Clamp locking pliers onto the head of the bolt. Heat the hub, then apply oil into the gap where the bearing enters the hub. Firmly grasp the pliers, and wrangle the assembly loose. <br/><br/> If the assembly is stuck, tap the side of the pliers with a hammer to help loosen it. If the bolt accepts a hex wrench (as does the factory supplied backing plate bolt), the wrench can be used instead of pliers.<br/><br/><br/>560.197S/C | Rupes LHR75e Bearing & Spindle Assembly.<br/>Install Tips for Rupes Replacement Parts 560.197/C and 56.245S/C.<br/><br/>Note: Although the LHR75e assembly is smaller and different in appearance, all of the listed procedures will work on the LHr75e's assembly.<br/><br/>Installing the new Bearing & Spindle Assembly.<br/> Option 1: Press the new bearing assembly into a heated & oiled hub by tapping the bearing assembly into the hub.  <br/><br/> Keep in mind that the shape of hubs vary.
