Disassembly
Remove the pump cover (162)
- Unscrew the four Allen screws (900) on the pump
housing cover. Using two flat screwdrivers and a plastic mallet, pry the cover off the
pump housing. Take care not to damage the large O-ring (412.0). The cover should
come loose easily.
Remove the pump rotor (230)
- Remove the plastic fan cover on the rear side of the
pump motor. Holding the fan by hand, unscrew the 15-mm nut of the pump rotor. (If the
15-mm nut is too tight to hold the shaft by hand, pry the fan off the shaft with two flat
screwdrivers, block the shaft with a round wrench). Pull the pump rotor off the shaft by
hand. Save the Woodruff key (940).
Remove the rotating SiC seal assembly (433)
- Unclip the seal spring from the rotating
seal assembly (use a flat screwdriver, lever on the pump housing). Remove rotating seal
assembly (consisting of: SiC seal cage, washer, O-ring). The assembly slides off easily,
by hand.
Remove the pump housing (107)
- Unscrew the four nuts (920), and remove the pump
housing from the motor. The pump housing may be stuck by paint - if necessary, insert
a knife blade between the pump housing and the motor to un-stick.
Remove the static SiC seal (433)
- An O-ring holds the static seal inside the pump
housing (107). The seal can be pushed out by hand.
