14. Remove blanking caps and connect air lines to
retarder solenoid, differential lock solenoid and
pressure reducing valve mounted on front bracket
assembly (1), as identified at removal.
15. Remove blanking caps from transmission oil cooler
lines and retarder ports and connect oil cooler lines.
Refer to Section 210-0060, TRANSMISSION OIL
COOLER.
16. Install main hydraulic pump on transmission PTO
and secure with mounting hardware removed during
removal. Refer to Section 230-0050, MAIN
HYDRAULIC PUMP.
17. Remove blanking caps and connect hydraulic lines
to the main hydraulic pump, as identified at removal.
18. Connect all drivelines to the transmission and
secure with mounting hardware removed during
removal. Refer to Section 130-0010, FRONT & REAR
DRIVELINES.
19. Prior to installing the cab, ensure that all connections
to the transmission, other than cab connections, are
connected securely and properly clipped.
20. Install the cab assembly on the front frame. Refer
to Section 260-0010, CAB AND MOUNTING.
21. Connect transmission harness at the cab floor and
earth strap between LH side of the transmission and
the frame.
22. Fill hydraulic tank with hydraulic oil specified in
Section 300-0020, LUBRICATION SYSTEM. Refer to
Section 230-0040, HYDRAULIC TANK for fill level and
procedure.
23. Fill transmission with engine oil specified in
Section 300-0020, LUBRICATION SYSTEM. Check
the oil level as described under 'Oil Level Check'.
24. Connect battery cables to battery terminal posts
(ground cable last).
25. Turn the battery master switch to the 'On' position,
start the engine and make an operational check of all
lines and electrical connections disconnected during
removal. Check for leaks and tighten lines and fittings
as required.
26. Ensure parking brake is applied, disconnect
steering lock bar and secure in the 'Stowed' position.
Remove wheel blocks from all road wheels.
27. Check for correct operation of the transmission,
shift selector and warning lights.
MAINTENANCE
Periodic Inspections
For easier inspection, the transmission should be kept
clean. Make periodic checks for loose mounting bolts
and leaking air and oil lines. Check the condition of
electrical harnesses and connections regularly.
Transmission breather (10, Fig. 2) should be checked
on a regular basis, and as frequently as necessary,
depending on operating conditions. A badly corroded
or plugged breather restricts proper breathing and
causes a buildup of condensation and subsequent oil
deterioration.
Oil Level Check
WARNING
When checking the oil level, be sure that the
parking brake is applied and all road wheels
are securely blocked.
Check the transmission oil level and add oil if low,
every 10 hours/daily. Use only oil specified in
Section 300-0020, LUBRICATION SYSTEM.
Because the transmission oil cools, lubricates and
transmits hydraulic power it is important that the
proper oil level be maintained at all times. If the oil
level is too low, the converter and clutches will not
receive an adequate supply of oil. If the oil level is too
high, the oil will aerate and the transmission will
overheat. It is absolutely necessary that the oil put into
the transmission is clean.
Cold Oil Level Check
This check is made only to determine if the
transmission contains sufficient oil for safe starting.
Make sure there is some oil showing on dipstick
(25, Fig. 1).
Hot Oil Level Check
1. Position the vehicle on a level work area, apply the
parking brake and block all road wheels securely.
2. With the transmission in neutral and the engine
running, allow the machine to idle until normal
operating temperature of 80° C (176° F) is achieved.
Transmission oil pressure gauge on the dash should
show a steady reading.
