Cab and Covers
12. Remove the mirrors and all other cab components
as needed, if not previously removed.
13. Carefully begin to lift the cab. Stop and check that all
wiring, hydraulic hoses and fasteners are
disconnected or removed.
14. 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.
15. 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.
16. Inspect the condition of the fittings, clamps, hydraulic
hoses, etc. Replace parts as indicated by their
condition.
17. 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. Install eyebolts and route a sling with a suitable
lifting capacity.
3. Use a hoist or overhead crane and sling attached to
the cab. 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 four bolts, washers and nuts and torque to
480 lb-ft (651 Nm).
5. Connect the throttle electrical cable from under the
cab.
6. Route any hoses through the opening at the right
rear corner of the cab.
7. Working under the cab, uncap and reconnect the
previously labeled hydraulic hoses to the appropriate
locations.
8. Connect the wire harness at the right front side of
the cab.
9. Connect the heater hoses to the engine. Secure with
two hose clamps. Open both coolant valves on the
engine.
10. Fill the cooling system completely with a 50/50 mixture
of ethylene glycol and water. The cooling system
capacity is listed in Section 2.4, “Fluid and Lubricant
Capacities.”
11. Connect the battery negative (-) cable or cables to
the battery negative (-) terminal.
12. Carefully examine all cab components, fasteners,
etc., one last time before engine start-up. Rectify any
faulty conditions.
13. Start the engine and check the operation of all controls.
Check for hydraulic fluid leaks. Check the hydraulic
fluid level in the tank and add fluid as required.
Note: When the engine is initially started, run it briefly at
low idle and check the machine for any visual sign of
fluid leakage. STOP the engine immediately if any
leakage is noted, and make any necessary repairs
before continuing.
14. Wait for the engine to cool and check the coolant
level. Add coolant to the overflow bottle as required
to bring the coolant to the proper level.
