NOTE: Securing roller assembly with a gap larger than
.060 inch (1.5 mm) creates a side load on bearings and
can lead to premature bearing failure.
3. Verify that there is no more than a .060 inch (1.5 mm)
gap between roller assembly and the roller mount brack-
ets of the deck frame. If this gap is larger than .060 inch
(1.5 mm), shim excess clearance with 5/8" washers.
