Special Tools Required
- Clutch Compressor Attachment 07ZAE-PRP0100
1. Inspect the clutch piston, the clutch discs, the clutch plates, and the clutch end-plate for wear and damage A/T Clutch Inspection, and inspect the clutch wave-plate phase difference A/T Clutch Wave-Plate Phase Difference Inspection, if necessary.
2. Install the 1st-hold clutch piston in the 1st clutch piston, and install 1st/1st-hold clutch piston (A) in the 1st clutch drum (B). Do not install the O-rings on the clutch pistons during inspection.
3. Install the 1st-hold clutch flat-plate (A), alternately install the 1st-hold clutch discs (B) (3) and the 1st-hold clutch wave-plates (C) (2), then install 1st-hold clutch plate B (D) with the flat side toward the top disc.
4. Measure the clearance between 1st-hold clutch plate B and the top disc using a feeler gauge (A) while pressing 1st-hold clutch plate B down. Take measurements in at least three places, and use the average as the actual clearance.
5. If the clearance is out of the standard, replace the 1st-hold clutch wave-plates and the 1st-hold clutch discs as a set, and recheck.
6. Install the disc spring (A) on 1st-hold clutch plate B in the direction shown. Starting with the 1st clutch wave-plate, alternately install the wave-plates (C) (5) and the clutch discs (D) (5) in the 1st clutch drum (E), then install the clutch end-plate (F) with the flat side toward the top disc.
7. Install the clutch pistons in the 2nd, 3rd, 4th, and 5th clutch drums. Do not install the O-rings on the clutch pistons during inspection.
8. Starting with the 2nd clutch flat-plate, alternately install the clutch flat-plates (A) (4) and the clutch discs (B) (4) in the 2nd clutch drum (C), and alternately install the clutch wave-plates (D) (3) and the clutch discs (B) (3). Install the clutch end-plate (E) with the flat side toward the top disc.
9. Install the disc spring (A) in the 3rd clutch drum (B) in the direction shown. Starting with the 3rd clutch flat-plate, alternately install the clutch flat-plates (C) (3) and the clutch discs (D) (3), and alternately install the clutch wave-plates (E) (2) and the clutch discs (D) (2). Install the clutch end-plate (F) with the flat side toward the top disc.
10. Install the disc spring (A) in the 4th clutch drum (B) in the direction shown. Starting with the 4th clutch flat-plate, alternately install the clutch flat-plates (C) (3) and the clutch discs (D) (3), and alternately install the clutch wave-plates (E) (2) and the clutch discs (D) (2). Install the clutch end-plate (F) with the flat side toward the top disc.
11. Install the disc spring (A) in the 5th clutch drum (B) in the direction shown. Starting with the 5th clutch flat-plate, alternately install the clutch flat-plates (C) (3) and the clutch discs (D) (3), and alternately install the clutch wave-plates (E) (2) and the clutch discs (D) (2). Install the clutch end-plate (F) with the flat side toward the top disc.
12. Install the snap ring using a screwdriver to secure the clutch end-plate.
13. Set a dial indicator (A) on the clutch end-plate (B).
14. Zero the dial indicator with the clutch end-plate lifted up to the snap ring (C).
15. Release the clutch end-plate to lower it, then put the clutch compressor attachment on the clutch end-plate (A).
16. Press the clutch compressor attachment down with 150-160 N (15-16 kgf, 33-35 lbf) (B) using a force gauge, and read the dial indicator (C).
17. The dial indicator reads the clearance (D) between the clutch end-plate and the top disc (E). Take measurements in at least three places, and use the average as the actual clearance.
18. If the clearance is out of the standard, select a new clutch end-plate from the following table.
1ST CLUTCH END-PLATES
2ND, 3RD, 4TH, and 5TH CLUTCH END-PLATES
19. Install a new clutch end-plate, and recheck the clearance. If the thickest clutch end-plate is installed, but the clearance is still over the standard, replace the clutch discs and clutch plates.
