CONTINUOUSLY VARIABLE TRANSMISSION(TR580) > Transfer Clutch Pressure Test

INSPECTION

CAUTION:

• Directly after the vehicle has been running or the engine has been idling for a long time, the CVTF is hot. Be careful not to burn yourself.

• Make sure no other person is around the vehicle during transfer clutch pressure test measurement.

1. Lift up the vehicle.

2. Remove the rear exhaust pipe from center exhaust pipe.

3. Remove the center exhaust cover.

4. Set the transmission jack under the transmission.

5. Remove the mounting bolt of rear crossmember.

6. Lower the rear side of transmission until the transfer clutch pressure test plug can be removed.

7. Using the ST, remove the transfer clutch pressure test plug.

8. Set the ST1, ST2, ST3 and ST4 to the transmission.

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.

9. Raise the transmission, and install the rear crossmember.

Tightening torque:

70 N·m (7.1 kgf-m, 51.6 ft-lb)

10. Install the rear exhaust pipe to center exhaust pipe.

Tightening torque:

18 N·m (1.8 kgf-m, 13.3 ft-lb)

11. Lower the vehicle.

12. Connect the Subaru Select Monitor to the data link connector and read the current data.

13. Check the transfer clutch pressure as in secondary pressure (line pressure) test. Secondary Pressure (Line Pressure) Test">

NOTE:

• Use Subaru Select Monitor for switching to FWD mode. AWD ON/OFF Switching Mode">

• If no oil pressure is produced, if it does not change in AWD mode or if oil pressure is produced in FWD mode, there may be a problem in the control valve body.

Tightening torque:

Calculation formula

T = L/(100 mm (3.94 in) + L) ? 22 N·m (2.2 kgf-m, 16.2 ft-lb)

T: Tightening torque

L: Effective length of torque wrench

NOTE:

If the effective length of the torque wrench used is unknown, consult the manufacturer of the torque wrench.

(a) Effective length of the ST2

(b) Effective length of the torque wrench

(d) Center of drive angle of the torque wrench

(e) Center of the position where a force is applied by hand

20. Raise the transmission, and install the rear crossmember.

Tightening torque:

70 N·m (7.1 kgf-m, 51.6 ft-lb)

21. Install the center exhaust cover.

Tightening torque:

18 N·m (1.8 kgf-m, 13.3 ft-lb)

22. Install the rear exhaust pipe to center exhaust pipe.

NOTE:

Use a new gasket.

Tightening torque:
