• Motor bearing set

Why service the Silensor SLL300 in one go

• The seal is the part that wears out on a pool pump: once it weeps, water heads for the motor.
• The motor is already off the pump to change the seal, so it’s the easiest time to change the bearings.
• The capacitor is a quick swap while you’re working on the pump, and if it has been slow to start, the capacitor is the first thing to check.

Before you order

Check the old parts before fitting: match the µF printed on your old capacitor and the size of your old seal.
