FRONT WHEEL SYSTEM
FRONT WHEEL REMOVAL AND BRAKE INSPECTION
1 Raise hopper and engage safety support.
2 Open broom-housing door (LH or RT) and remove the top gasket seal (so not to damage). Place jack towards front of housing and jack on
machine frame to where the front wheel clears the floor.
3 Place safety blocking under the front frame member to support.
4 Remove the Wheel Screw (A) then work the tire off of wheel spindle. Note: the parking brake must be released to allow wheel to be removed.
Also tap on the backside of wheel with wood blocking to help loosen a stubborn stuck wheel.
5 Inspect the spindle; wheel bearings and brake shoe linings for abnormal wear and replace all worn parts. A new brake shoe lining thickness
will measure 11/64 (.172) inches or 4.4 mm.
6 Check for approximately one inch (25mm) of operator brake pedal free-play (see instructions below to adjust) and test drive machine for proper
operation.
FRONT BRAKE SHOE ADJUSTMENT
1 Raise hopper and engage safety support.
2 See Figure 1. Remove the (6) Philips Screws (B) then pull the broom Housing Skirt (C) to the side to access the brake cable clevis.
3 See Figure 1 detail of clevis adjustment, length or shorten its threaded end to obtain the correct brake pedal free play. Note both brakes (LH
& RT) need to be adjusted equally.
4 If the brake cable clevis adjustment does not eliminate excessive pedal travel (poor braking performance) check for worn out brake shoes
and a stretched brake cable. The ends of the brake cable at the wheels have adjustable threaded cable anchor fittings. Shorten the length
of cable wire extending out of the cable casing by adjusting the cable anchor fittings at the wheel casting pocket (inset).
BRAKE CABLE REPLACEMENT
1 Follow the scrub deck removal instruction in the scrub system manual section. The removal of the deck is necessary to access the brake pedal
cable guide pulley and cable anchor points (location middle of machine under operator floor plate).
2 See the brake shoe adjustment instructions above to remove the brake cable ends at the wheels.
