Transfer Clutch Pressure Test: Inspection
WARNING: This page is about a different variant/trim than selected.
- Lift up the vehicle.
- Remove the test plug.
- Set the ST1, ST2, ST3 and ST4 to the transmission.CAUTION: Be careful when setting tools so that the hoses do not touch the exhaust pipes.NOTE:
- Use ST1 ADAPTER HOSE B with genuine union screw (Part No. 801914010) and gasket (Part No. 803914060) attached.
- Use ST3 PRESSURE GAUGE ADAPTER with genuine O-ring (Part No. 806911080) attached.

- Lower the vehicle.
- Connect the Subaru Select Monitor to the data link connector and read the current data.
- Check the transfer clutch pressure as in secondary pressure (line pressure) test. Ref. to
SECONDARY PRESSURE (LINE PRESSURE) TEST NOTE:
- Turn OFF the X mode switch and perform inspection.
- If oil pressure is not produced or it does not change, the control valve body may be malfunctioning.

- Remove the ST.
- Install the test plug using ST1 and ST2.NOTE:

ST2 73099SG000 SPECIAL TOOL CONDENSER
Using the following formula, calculate the tightening torque for a torque wrench.
T2 = L2/(L1 + L2) x T1
T1: 25 N.m (2.5 kgf-m, 18.4 ft-lb)
L1: ST2 length 0.1 m (3.94 in) (a)
L2: Torque wrench length (b) m (in)
[Required torque setting]
T2: Tightening torque: N.m (kgf-m, ft-lb)
- Lower the vehicle.
