Inspection, Maintenance and Adjustment
Replace Pipes and Hoses
1.
Replace hoses that carry brake fluid to wheel brakes.
Also replace hoses that carry hydraulic fluid to steering
cylinders.
2.
It is difficult to determine condition of many hoses. The
best way to ensure safe operation and to maintain
maximum performance is to replace hoses on a regular
basis. If any brake or steering hoses become damaged
or appear defective in any way, replace them
immediately despite time interval since their last
replacement.
Bleed Brakes
When brake hoses or brake tubes are replaced, air can be
introduced into brake hydraulic system. Air can cause brakes
to operate intermittently, which is a dangerous condition.
Never operate machine with air in brake hydraulic system. A
spongy feel when pressing brake pedal is a sign that air is
present in brake hydraulic system.
To bleed air out of brake hydraulic system, perform the
following steps: (Figure 102)
1.
Start engine and place transmission in "NEUTRAL."
2.
Remove rubber cap from bleeder screw on wheel.
3.
Place one end of a plastic hose (2) over bleeder screw
(1). Place other end of hose in a container (3) filled
with brake fluid.
4.
Station one person in operator’s cab, and one person
at bleeder screw on wheel being bled.
5.
Open bleeder screw (1). Then press down on brake
pedal until it rests on floor of cab. Hold pedal down on
floor of cab. Close bleeder screw while pedal is being
held down. After bleeder screw has been closed, allow
brake pedal to return to upright position. Continue to
open bleeder screw and press down pedal as
described in this step, until fluid expelled from bleeder
hose has no air bubbles present.
6.
Securely close bleeder screw (1). Install rubber cap on
bleeder screw.
