Shaft Seal Replacement
1. Stop the agitator and isolate the electric motor from the mains supply.
2. Remove the Cover Plate to access the shaft clamp.
3. Loosen Cap screws on the agitator shaft clamp. Ensure the Flinger is still
firmly clamped to the shaft before doing this as the shaft will drop slightly
until the flinger rests on the bottom of the support housing. (This prevents
the agitator shaft from dropping into the tank)
4. Remove 4 off M8 Hexagon nuts
and lift off the Motor / Gearbox
assembly.
5. Remove the fasteners attaching
the support housing to the tank.
6. Lift the support housing to give
access to the agitator shaft and
temporarily clamp the shaft to
prevent it dropping into the tank.
7. Loosen the grub screws
clamping the Flinger to the
agitator shaft and remove the support housing.
8. Remove the worn shaft lip seal and insert a new seal.
9. Reassemble agitator.
