Front Roller Service
Disassembly (Fig. 18)
1. Remove roller mounting bolt.
2. Remove roller assembly from carrier frame.
3. To remove bearings and bearing spacer:
A. Insert punch through end of roller and drive oppo-
site bearing out by alternating taps to opposite side of
inner bearing race. There should be a lip of inner race
exposed for this process.
B. Remove bearing spacer. Remove second bear-
ing from roller using a press.
4. Inspect roller housing, bearings and bearing spacer
for damage or wear. Replace components as needed.
Assembly (Fig. 18)
1. Install bearings and bearing spacer into roller:
IMPORTANT: Use Front Roller Bearing Installation
Tool (see Special Tools in this chapter) when in-
stalling bearings into roller. This tool ensures that
no side load is applied to the bearings during install-
ation into the front rollers.
A. Press first bearing into housing. Press equally on
inner and outer races during installation.
B. Insert bearing spacer.
C. Press second bearing into roller housing press-
ing equally on inner and outer races until the inner
race comes in contact with the bearing spacer.
2. Install roller assembly to deck frame.
NOTE: Securing roller assembly with a gap larger than
0.060 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 0.060 inch (1.5
mm) gap between roller assembly and the roller mount
brackets of the deck frame. If this gap is larger than
0.060 inch (1.5 mm), shim excess clearance with 5/8”
washers.
4. Insert mounting bolt and tighten to 65 to 95 ft−lb (89
to 128 N−m).
