Bell Cup Removal Tool
A11247-00 (65mm Bell Cups Only)
(Optional Accessory)
This tool is meant to aid in the removal of bell
cups that are abnormally tight on the spindle
shaft. Typically, bell cups are easily removed by
hand with the aid of the standard bell cup wrench
(A12061-00). To prevent bell cups from becoming
difficult to remove, care should be taken to remove
wet or old dried paint from shaft and bell cup taper
and threads before bell cups are assembled to
the atomizer.
Before using the bell cup removal tool, clean the
exterior of the bell cup with clean solvent and dry
it. This will improve the tool's ability to grip the
cups surface.
To install the tool, first engage the bell cup wrench
(A12061-00) to the shaft hex behind the bell cup.
Place the bell cup tool (A12247-00) over the front
of the bell cup and tighten the knurled portion
in a counter-clockwise direction until very tight
(left hand thread). (See Figure 28 for proper en-
gage-ment of tool on bell cup.) While holding the
bell cup wrench on the spindle shaft, grasp the
T-handle on the bell cup tool and turn in a count-
er-clockwise direction until bell cup is loosened. If
tool rotates or slips, tighten tool further and retry.
To re-install a cup, position the wrench as shown.
Insert a torque wrench into the square in the wrench
to apply approximately 50-70 lbs•in (5.64-7.91
Nm) torque. Hold the cup and tighten the torque
wrench in a counter-clockwise direction.
