Removal
When removing, please pay attention to the following operations:
1. Remove the gearbox.
2. Remove the clutch housing and disc.
a) Apply marks to the clutch housing and flywheel.
b) Loosen each set bolt one turn to ensure the spring releases evenly from preload.
c) Remove all mounting bolts and remove the clutch housing and clutch disc from the engine flywheel.
3. Remove the clutch release fork and release bearing.
a) Remove the bracket and take out the release bearing.
b) Remove the clutch release fork.
Installation
Note: Installation is carried out in the reverse order of removal.
1. Using a centering mandrel, install the clutch driven disc.
Note: Do not confuse the direction of disk installation.
2. Install the clutch cover.
a) Align the previously applied timing marks on the casing and flywheel.
b) Tighten the mounting bolts in the order shown in the figure.
- Tightening torque - 19 Nm
Note:
- Tighten the bolts in several stages.
- By moving the centering mandrel slightly, make sure that the disc is in the center position.
Clutch.
1 - clutch housing,
2 - clutch disc,
3 - bolt,
4 - clutch fork lever,
5 - spring,
6 - bushing,
7 - fork,
8 - release bearing assembly.
3. Check the relative position of the diaphragm spring petals.
- Maximum deviation from plane - 0.7 mm
If the deviation exceeds the permissible value, use a special tool to adjust the relative position of the ends of the spring petals.
Examination
1. Using a caliper, measure the depth of the rivets from the lining surfaces.
- Minimum depth - 0.3 mm
(The original can be viewed on the website: www.ToyotaMan.ru)
If the depth is less than the permissible value or the disc wear is uneven, replace the clutch disc.
2. Rotate the bearing by hand, applying force to it in the axial direction. Replace the bearing if it sticks or turns with difficulty.
Note: The release bearing is lubricated for life and does not require cleaning or lubrication.
3. Using a dial indicator, check the flywheel runout.
- Maximum permissible runout is 0.1 mm
If the measured runout exceeds the maximum permissible value, replace the flywheel.
