Bell Cup Removal/Replacement
>The bell cup should always be the first com-
ponent removed if any maintenance is per-
formed. Following the procedure will minimize
the risk of damage to the cup itself.
Using the large open end of the wrench
(A12061-00) on the flats of the turbine shaft,
carefully hold the outside of the bell cup with
one hand while applying a clockwise force to
the wrench. The bell cup is a right hand
thread and must be turned counter-clockwise
to remove. Use latex gloves to obtain a firmer
grip on the cup.
Place the bell cup in a safe, secure place.
Carefully inspect the cup for any damage. If
there is any damage to the cup, it must be re-
placed.
> Failure to replace a damaged bell cup will
cause premature turbine failure. Warranty
will not be honored if the bell cup is damaged.
To re-install a cup, position the wrench ad
shown. Insert a torque wrench into the square
in the wrench to approximately 50-70 Lbs.- In
(5.65- 7.9 Nm) torque. Hold the cup and tight-
en the torque wrench in a counter- clockwise
direction.
> There is a 3- inch center-to-center distance
between the bell cup and the 3/8 inch socket
square on the wrench. This distance must be
factored in when reading the proper torque on
the wrench.
