Introduction

Power Steering
The power steering valve is enclosed in the steering
tower at the front of the traction unit. As the steering
wheel is turned, the steering valve meters hydraulic fluid
to the double-acting steering cylinder on the rear axle
and turns the wheels. Hydraulic fluid flow for power
steering is supplied by the front section of auxiliary
hydraulic pump. The steering section of the pump has
a built-in relief valve.
The Model HGF Hydraguide
manufactured by TRW, Ross Gear Division.
NOTE: Because the steering cylinder has different dis ­
placements when extended and retracted, the steering
wheel will not return to its original position after making
a turn.
NOTE: The steering system will operate with the engine
off if necessary (with increased effort).
Brakes
®
The Reelmaster 5100-D is equipped with 7 inch di­
ameter x 1-3/4 inch wide mechanical drum brakes on
the front wheels (Fig. 2).
Two pedals are used to control the brakes. When used
separately, the pedals can control each wheel brake to
assist steering or traction on side hills. The two pedals
may be locked together with the brake lock arm. When
the lock arm is engaged both wheels will brake equally
and act as a service brake or parking brake.
The brake pedals operate the brakes through a cable
system to a strut and lever on the brake shoes.
