CVT Reassembly

Special Tools Required
Reverse brake spring compressor (  07TAE-P4V0110)
 

Start clutch installer (  07TAE-P4V0130)
 



1.Soak the reverse brake discs thoroughly in ATF for a minimum of 30 minutes.

2.Install the dowel pins (2) (A) and the new gasket (B) on the transmission housing (C).

 

3.Push the control shaft (D) toward the outside of the transmission housing, then install the intermediate housing (E).

4.Put the control shaft back, then install the roller (F) in the intermediate housing with aligning the groove on the control shaft.

5.Install the new O-rings (A) on the reverse brake piston (B), then install the piston in the intermediate housing (C).

 

6.Install the spring retainer/return spring assembly (D); install the return springs on the spring guide (E) on the reverse brake piston.

7.Install the special tool through the drive pulley shaft to compress the return spring. Be sure the special tool (spring compressor attachment) is set over the return springs, not to over the reverse brake piston.

 

8.Compress the return springs with making sure that the special tool set over the return springs and the spring retainer tabs does not ride on the reverse brake piston.

 

9.Install the snap ring in the intermediate housing above the spring retainer, and remove the special tool.

10.Verify that the snap ring end gap (A) is 15 mm (0.59 in.) and above.

 

11.Install the disc spring (A) on the reverse brake piston in the direction shown.

 

12.Starting with the reverse brake plate (B), alternately install the plates and discs (C). Install the reverse brake end plate (D), then install the snap ring (E).

13.Verify that the snap ring inside diameter (A) is 143.5 mm (5.65 in.) and above, and also the snap ring end gap (B) is 18 mm (0.71 in.) and above.

 

14.Set a dial indicator (A) on the reverse brake and plate (B).

 

15.Zero the dial indicator with lifting the top disc (C) up to contact the reverse brake end plate to the snap ring (D).

16.Release the end plate to lower the end plate, and place a steel plate across width of the reverse brake end plate.

17.Press the steel plate (A) down with 40 N (4 kgf, 9 lbf) using a force gauge, and read the dial indicator (B). The dial indicator reads the clearance (C) between the reverse brake end plate (D) and top disc (E). Take measurements in at least three places, and use the average as the actual clearance.

STANDARD: 0.55 - 0.70 mm (0.22 - 0.028 in.)
