9. Connect driveline to the transmission and secure
with mounting hardware removed during removal. Refer
to Section 130-0010, DRIVELINE.
10. Install air tanks and mounting bracket to the
machine. Refer to Section 250-0170, AIR TANKS AND
MOUNTING.
11. 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.
12. Fill transmission with engine oil specified in Section
300-0020, LUBRICATION SYSTEM. Check the oil
level as described under 'Oil Level Check'.
13. Connect the following cables and connectors in the
order given to prevent serious damage to the engines
electrical components.
a - Transmission ECU connector
b - Alternator supply cables
c - Alternator earth cables
d - Battery supply cables
e - Battery earth cables
14. 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. Allow transmission to warm up and
recheck all connections for leaks.
15. Ensure parking brake is applied and remove wheel
blocks from all road wheels.
16. 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 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. Add oil if low.
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 for approximately
20 seconds (until normal operating temperature of
80° C (176° F) is achieved).
3. With parking brake applied, foot on service brake,
engine idling and transmission operating at normal
temperature, select each gear position in turn. Allow
the transmission to remain in each gear for 5 - 10
seconds.
4. Return gear selector to neutral and, with the engine
idling, check the oil level on dipstick. Oil level should
be up to, but not over, the upper mark on the dipstick.
Add oil if low.
Oil and Filter Change
After the first 50 hours of operating a new or rebuilt
transmission, the transmission oil and filter cartridges
(14, Fig. 2) should be changed. Internal filter and finger
magnet at the lower front left hand of the sump should
be removed and cleaned.
The transmission oil and filter cartridges should be
