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 sling with suitable lifting capacity through
the previously installed eye bolts.
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. Take
special note of the fuel fill tube as well. Readjust the
position of the sling as needed to help balance the
cab during installation.
4. Install the cab-to-frame bolts, washers and nuts.
Torque to 110 lb-ft (150 Nm).
5. Remove the eye bolts from the top of the cab.
6. Connect the throttle cable rod end to the throttle
extension bracket (1) underneath the cab.
7. Uncap and reconnect the hydraulic hoses at the cab
locations.
8. Secure the throttle cable to the hydraulic hoses
using wire ties.
9. Uncap and connect the heater hoses to the engine.
Secure with hose clamps.
10. Install the cab-to-wiring harness connectors on side
of the cab.
11. Fill the cooling system completely with a 50/50 mixture
of ethylene glycol and water, allowing time for the
coolant to fill the engine block. The cooling system
capacity is listed in Section 2.4, “Fluids, Lubricants
and Capacities.”
12. Connect the battery negative (-) cable to the battery
negative (-) terminal.
13. Carefully examine all cab components, fasteners,
etc., one last time before engine start-up. Rectify any
faulty conditions.
14.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.
IMPORTANT: 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.
15. 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.
16. Close and secure the engine cover.
