Bearing Replacement
- To remove bearing in drive frame end, detach retainer plate screws and press bearing from frame. If bearing is in good condition, it can be reused. However, fill it 1/4 full with lubricant. To install bearing, press in with a tube or collar that just fits over outer race. Install new retainer plate if felt seal is hardened or excessively worn. Fill cavity between retainer plate and bearing with lubricant.
- Replace bearing in slip ring end frame if its grease supply is exhausted. Do not attempt to relubricate or reuse bearing. Press bearing from outside of housing toward the inside, using a tube or collar just fitting inside end frame housing.

Press seal in with lip of seal toward rotor, away from bearing. Coat seal lip lightly with oil to aid in later assembly.
