20 Series Opener Side Wheels
Refer to Figure 72
1. Lift opener side wheel off the ground. Move tire in
and out to check for end play. Check for roughness
in bearing by rotating wheel. If the bearings are
rough, inspect and replace if necessary.
2. Check for the correct number of flat washers (1)
and machine washer (8) between the side gauge
wheel (2) and the wheel arm (3). There must be
three flat washers (1) and one machine washer (8)
between the wheel bearing and arm with the
machine washer (8) next to the arm. There should
be three flat washers (1) and one lock washer (9)
on the outside of the wheel. When installed, the
wheel should turn freely and not hit the arm at the
curve. Do not add any more washers than
necessary.
3. Disassemble side-gauge-wheel arm from unit.
Remove bushing (4) from sleeve (5) and check
bushing for wear. Replace bushing if necessary.
4. When reinstalling side gauge wheels, align tab on
hex adjustment (6) with notch in bushing. Replace
bolt and tighten.
