4.3.2 Carrier Roller Inspection and Replacement
Inspecting a Carrier Roller
Carrier rollers should have 1/16 to 1/8-inch end play. A bent frame or bracket may
bind the rollers. If the rollers do not rotate freely, make sure the between-frame (BF)
dimension is correct, and replace or adjust frame components as necessary. If the
roller is free in the frame but still sluggish in operation, replace the roller.
