Ransburg RMA Indirect A11600 - Manual (Page 57)

Bell Cup Removal/Replacement
Using the large open end of the wrench (A12061-
00) on the flats of the turbine shaft, carefully hold
the ouside 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.
> Failure to replace a damaged bell cup
will cause premature turbine failure.
Warranty will not be honored if the bell
cup is damaged.
C A U T I O N !
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 replaced.
To re-install a cup, position the wrench as 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 tighten the torque
wrench in a counter-clockwise direction.
>
The bell cup should always be the first
component removed if any maintenance is
performed. Following the procedure will
minimize the risk of damage to the cup
itself.
NOTE

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.
