Transfer Clutch Pressure Test: Inspection

WARNING: During the transfer clutch pressure test, confirm safety in the vicinity and make sure no person is around the vehicle.

CAUTION: Vehicle components are extremely hot immediately after driving. Be wary of receiving burns from heated parts.

Check the engine oil level. Ref. to LUBRICATION (H4DO)>ENGINE OIL>INSPECTION .
Check the engine coolant level. Ref. to COOLING (H4DO)>ENGINE COOLANT>INSPECTION .
Remove the front wheel RH. Ref. to WHEEL AND TIRE SYSTEM>TIRE AND WHEEL>REMOVAL .
Remove the test plug (transfer clutch pressure), and install ST1 and ST2.
CAUTION:
- Because the CVTF will flow out, install the ST quickly.
- Be careful when setting the tool so that the ST does not touch the exhaust pipe.
NOTE:
- Prepare the container for draining of engine oil.
- Use the ST1 with genuine O-ring (part No. 806908150) attached.
- Use the ST2 with genuine O-ring (part No. 806911080) attached.
Preparation tool:

ST1: OIL PRESSURE GAUGE ASSY (498575400)

ST2: PRESSURE GAUGE ADAPTER (18681AA000)
