3 Right Side Charge Roll Link
Right Charge Roll Bushing
Action
Check the right side charge roll link
assembly for correct assembly
operation. If incorrect, replace the
charge roll link assembly with the
charge roll link assembly kit. If
correct, check the right charge roll
link assembly bearing for signs of
wear or contamination. Excessive
contamination could cause
intermittent charging of the charge
roll. If incorrect, replace the link
assembly. Check for continuity of the
right link assembly from the bearing
to the charge roll high voltage
contact on the right side frame. If
incorrect, replace the link assembly.
Make sure the charge roll bushing is
installed and operating correctly.
Note: The screw that attaches the
charge roll lead to the contact must
be secure.
