CHECKING THE OIL PRESSURE IN THE AM6 AUTOMATIC GEARBOX
Checking the torque converter.
WARNING: This check has to be of short duration (2 seconds), as it causes a rapid
rise in the temperature of the oil in the automatic gearbox.
Respect the following checking conditions:
- Engine at operating temperature.
- Gear lever in position D.
- Press on the brake pedal.
- Accelerate the engine to the maximum engine speed (see below).
Gear lever position.: D.
Maximum engine speed for ES9A : 2400 ± 50 rpm.
Maximum engine speed for DT17 : 2600 ± 50 rpm.
Diagnosis:
- If the maximum engine speed obtained is lower than the value indicated, the torque
converter is the cause.
- If the maximum engine speed obtained is higher than the value indicated, the automatic
gearbox is the cause (slipping).
Additional operations.
Remove tools [1]and [2].
Refit the screw (2), with a new seal.
Reposition the pipe (1).
Refit the air filter housing.

Compressor lubricant
ESSENTIAL: The compressor lubricant is extremely hygroscopic; always use FRESH oil.
Checking the compressor oil level
There are three specific cases:
- 1)Repairs to a system without leaks.
- 2)Slow leak.
- 3)Fast leak.
1) Repairing a system without leaks.
a) - Using draining/recovery equipment not fitted with an oil decanter.
- Drain the system as slowly as possible via the LOW PRESSUREvalve, so as not to lose any oil.
- No more oil should be added when filling the system with R 134.afluid.
b) - Using draining/filling equipment fitted with an oil decanter.
- Drain the R 134.afluid from the system in accordance with the instructions in the equipment handbook.
- Measure the amount of oil recovered.
- Add the same amount of NEWoil when filling the system with R 134.afluid.
c) - Replacing a compressor.
- Remove the old compressor, drain it and measure the oil quantity.
- Drain the new compressor (supplied full), so that the same amount of NEWoil is left in the compressor as was in the old compressor.
- No more oil should be added when filling the system with R 134.afluid.

Checking the compressor oil level (continued)
2) Slow leak.
Slow leaks do not lead to oil loss, therefore the same procedure should be followed as if there was no leak at all.
3) Fast leak.
This type of leak causes both oil loss as well as allowing air to enter the system.
It is therefore necessary to:
- Replace the dryer.
- Drain as much oil as possible (when replacing the faulty component).
Either before or during filling of the system with R 134.afluid, introduce 80 ccof NEWoil into the system.
If changing one of the following components, add as below:
- A drying bottle : 15 ccof compressor oil.
- A condenser or an evaporator : 20 cc of compressor oil.
- A high pressure or low pressure pipe : 5 ccof compressor oil.
- A drying cartridge : 15 ccof compressor oil.
