1B3-102 OM600 ENGINE MECHANICAL
Checking
Notice
The noise which continues short time during short travel
(frequent starting of the engine) or engine starting after a
long time storage is normal operating conditions. So, it does
not need to be repaired. Determine the malfunctions in valve
clearance compensation device with noise through following
tests. If defective, replace as respectively.
1. Run the engine at more than 3000rpm for approx. 4 minutes.
2. Stop the engine. After 5minutes, check the engine oil level
and adjust if necessary.
3. Remove the cylinder head cover.
4. Check the valve tappets at TDC position of each cylinders.
5. Using a drift, lightly press the valve tappet and measure
clearance between the cam and valve tappet.
Notice
If the clearance exceeds 0.4mm, replace the valve tappet.
6. If a valve tappet moves down too far in comparison to the
others, replace the valve tappet.
7. Rotate the engine and check the remaining valve tappets.
Notice
lUnnecessary rotation of the engine will damage the valve
tappets.
lDo not rotate the engine by using the camshaft sprocket
bolt or to the opposite direction of the engine rotation.

BLEEDING THE BRAKES
For Master Cylinder Replacement
1. Add oil after master cylinder replacement.
2. Run the engine and depress the brake pedal several times
to build pressure and then keep the pedal fully depressed.
3. Loosen the screws of primary and secondary pipe at the
master cylinder outlets to bleed air.
4. Repeat above step No.3 several times until there are no
more air bubbles.
5. Bleed air in the system at the hydraulic unit outlet pipe and
wheel if pressure building is not enough by depressing the
pedal only after above air bleeding.
For Caliper and Brake Hose Replacement
1. Check the oil level from the oil reservoir and refill if necessary.
2. Run the engine and depress the pedal several times to
build pressure and then keep the pedal fully depressed.
3. Connect a vinyl tube to the caliper breather and prepare a
container to coentain brake oil.
4. Loosen the breather screw until there are no more bubbles.
5. Bleed air in the system at four (4) wheels in order as shown
in right figure if pressure building is not enough by depressing
the pedal after above air bleeding.

AUTOMATIC TRANSMISSION 5A-69
MECHANICAL TESTS
In Vehicle Transmission Checks
Carry out the following tests before removing the transmission.
lSee Checking Transmission Fluid Level, Section 7.2.1.
lCheck that the transmission oil is not burnt (colour and smell are correct).
lEnsure that the transmission is not in limp home mode (LHM).
lCheck that the battery terminals and the earth connections are not corroded or loose.
lCheck the engine stall speed is within the handbook value.
lCheck that the cooler flow is not restricted.
lCheck that all electrical plug connections are tight.
lCarry out a road test to confirm the symptoms, if necessary.
lInspect the oil, ensure that there are no metal or other contaminants in the oil pan.
Diagnosing Oil Leaks
Determine the source of oil leaks by firstly cleaning down the affected area, then driving the vehicle.
Inspect the seals to confirm the source of the leak.
lTo determine the source of a rear servo oil leak, raise the vehicle on a hoist, then carry out a reverse stall.
lTo determine the source of a front servo leak, raise the vehicle on a hoist, then run the vehicle in second gear.
Troubleshooting Charts
The troubleshooting charts are set out as follows:
lTable 6.2.1 Drive Faults,
lTable 6.2.2 Faulty Shift Patterns.
lTable 6.2.3 Shift Quality Faults.
