Servicing Rotor, Vanes, and Shaft Seals
The rotor, vanes, and shaft seals are inside the pump housing, and are accessed through
the rotor cover located on the face of the pump. It is held in place with three 4mm hex
drive attaching bolts. You can access the rotor and vanes for inspection and cleaning,
butDO NOT attempt to remove the shaft seals without a new seal kit to install.
Always inspect the rotor cover seal and mating surface (groove) for nicks or damage prior
to reassembly. Be certain o‑ring is not pinched to prevent leakage. Torque the attaching
hardware to 44 in‑lbs.
