The standard motor for the W+ pump has a front-mounted bearing. If
the motor is replaced, the new motor must also have a front-mounted
bearing. The motor bearing is enclosed and permanently lubricated.
Follow the instructions below when replacing the motor. For replace-
ment of bearings, see the motor supplier's service instructions.
