BEARING INSPECTION

1. Rotate the clutch bearing in both clockwise and
counter-clockwise directions.
• Non-EBS: The non-braking bearing should rotate
both directions on the shaft with only a slight
amount of drag.
• EBS: The one-way bearing should rotate clockwise
(when viewed from cover plate side) with only a
slight amount of drag. When rotated counter-
clockwise the one-way bearing should lock to the
shaft without slipping.
2. Verify there is no binding or rough spots. If problems
are noted continue with disassembly.
