NOTE: Securing roller assembly with a gap larger than
.060 inch (1.52 mm) creates a side load on bearings and
can lead to premature bearing failure.

mm) gap between roller assembly and the roller mount
brackets of the deck frame. If this gap is larger than .060
inch (1.5 mm), shim excess clearance with 5/8” wash-
