Whipper System Maintenance-Cont'd
Replacing Worn Components – Cont'd
When replacing the seal [781566] on the whipper base, pay careful
attention to the alignment marks on both the seal and the base. If the
two are not properly aligned, the hole in the seal [for the motor shaft]
will be oval shaped and not round. This will allow liquid to get past the
seal and possibly into the whipper motor.
After replacing the seal, inspect the larger rubber O-ring [767390] in the
base for cuts, nicks, and deformities. If the O-ring appears damaged in
any way, it should be replaced.
After servicing the whipper, add some Lubrifilm lubricant
to the whipper motor shaft prior to re-installing the base
onto the motor.
