to Section 4.3.4, a. “Joystick Assembly Removal.”
Route the joystick cables through the opening at the
bottom of the cab.
14. Working under the cab, label, disconnect and cap
the hydraulic hoses at the cab fittings (4). Cap all
fittings to keep dirt and debris from entering the
hydraulic system.
15. If necessary, remove mirrors and other cab
components that may become damaged during cab
removal.
16. Attach a clevis (5) to each of the cab lifting brackets.
Route a sling (16) with a minimum lifting capacity of
1000 lb (453 kg) to a hoist or overhead crane. Center
the sling to ensure even lifting.
17. Remove the two upper cab-to-frame capscrews and
two flat washers.
18. Remove the two lower cab-to-frame capscrews and
two flat washers.

wiring, hydraulic hoses and fasteners are
disconnected and removed.
20. When all wiring, hydraulic hoses and fasteners are
disconnected or removed, carefully and slowly lift
the cab and remove it from the frame. Readjust the
position of the sling as needed to help balance the
cab during removal.
21. When the cab is completely clear of the machine,
carefully lower it to the ground. Block up or support
the cab so that it does not move or fall. Assure that
no personnel enter the cab while it is being removed
from the machine.
22. Inspect the condition of the fittings, clamps,
hydraulic hoses, etc. Replace parts as indicated by
their condition.
23. Inspect and replace other machine parts that are
exposed with the cab removed. Repair or replace as
required.
4.5 CAB INSTALLATION
1. Block all four wheels to help prevent the machine
from moving. Assure that there is sufficient overhead
and side clearance for cab installation.
2. Attach a clevis (5) to each of the cab lifting brackets.
Route a sling (6) with a minimum lifting capacity of
1000 lb (453 kg) to carry the weight of the cab
through the clevis’ to a hoist or over head crane.
Make sure the sling is centered between the clevis’
to ensure even lifting.
3. Carefully begin to align the cab with the mounting
holes in the frame. Stop and check that wiring,
hydraulic hoses, cables, etc. will not be pinched or
damaged as the cab is positioned. Readjust the
position of the sling as needed to help balance the
cab during installation.
4. Install the two upper cab-to-frame capscrews and
washers. Torque to 480 lb-ft (651 Nm).
5. Install the two lower cab-to-frame capscrews and
washers. Torque to 480 lb-ft (651 Nm).
