Preparation for Towing/Winching
from machine no. 676355
The braking system components on this machine are integral
with the hydraulic drive motors and are covered in
Section E
Hydraulics
.
Since the brakes are locked 'ON' whenever the engine is
stopped, the following procedures should be followed before
attempting to move a disabled machine.
It is only possible to tow or winch the machine for short
distances at slow speed in a straight line. This is because the
steering function is inoperative unless the machine is being
self-propelled.
If at all possible repair the disabled machine where it stands.
If the machine needs to be returned to the workshop for
repair, it must be winched onto a trailer or lifted onto a truck
for transportation.
!
!
CAUTION
DO NOT attempt to tow/winch the machine without first
releasing the hydrostatic braking otherwise damage will
occur to the hydraulic pumps.
3-2-1-2
1
Block the wheels to prevent accidental movement when
the brakes are released.
2
Remove the floor plates to gain access to the hydraulic
pump assembly.
3
Press in the by-pass plungers on the four Charge Check
valves
A
underneath the pump. This will open the valves
and allow oil from the motors to flow freely through the
pump. The valves will stay open until the machine is next
started when charge pressure will automatically close
the valves.
4
Unscrew plug
B
on each motor end cover. Store the
plugs in a safe place.
5
Using locally made pullers, jack out the brake piston to
release the brake. The pullers must be constructed so
that they rest on the outer edge of the motor casing and
have a central bolt to screw into the tapped hole in the
brake piston (see illustration).
Note:
DO NOT rest the puller against the central part of the
motor end cover or the cover will be distorted.
6
Screw the M12 bolt in finger tight and then turn a further
one complete turn to release the brake. Use washers
under the bolt head if necessary to give correct thread
engagement.
7
Remove the wheel blocks only when the machine is
hitched up ready for towing/winching. Keep personnel
clear of the machine while the blocks are removed.
After Towing/Winching
1
Remove the brake piston pullers and refit plugs
B
. Refit
the floor plates.
