Shaft Seal Replacement
The lip type shaft seal (Item 6) can be replaced without
disassembly of the motor; however, replacement of the
seal requires removal of the motor from the transaxle.
Pry the seal carefully out of the housing bore, using care
not to distort the housing or damage the bore or shaft.
Once removed, the seal is not reusable.
