Ransburg MMA-570 Direct_Ind Charge Atomizer A13366 - Manual (Page 61)

To reinstall a cup, position the wrench as shown.
Insert a torque wrench into the square in the
wrench to approximately 50-60 lbs•in (5.65-7.9
Nm) torque. Hold the cup and tighten the torque
wrench in a counter-clockwise direction.
NOTE - True torque.

Example: A desired true torque is desired using
a 9-inch effective length torque wrench. Wrench
offset is 3-inches.
L = 9-inches
TT = 50lbs•in
E = 3-inches
DR = is dial reading.
DR =50 (9)
(9+3)
DR =37.5 lbs•in

Bell Cup Removal Tool A12247-00 (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 “Tool/Bell Cup Engagement”
figure for proper engagement 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 counter-clockwise direction until bell cup
is loosened. If tool rotates or slips, tighten tool
further and retry.
NOTE
† There is a 3-inch center-to-center dis-
tance 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.
