Attention:
- When removing a manual transmission from a vehicle, always replace the concentric slave cylinder (CSC). To remove the manual transmission, the CSC insert is returned to its original position. Dust on the sliding components of the clutch drive plate can damage the CSC seal and cause brake fluid leakage.
- Avoid getting grease on the surface of the clutch driven disc, pressure plate and flywheel.
Removal
1. Remove the manual transmission from the vehicle. See chapter Manual transmission.
2. Loosen the clutch housing mounting bolts evenly. Remove the clutch housing and clutch driven disc.
Checking and adjusting after removal (cR engine)
Clutch slave disc
Measure the runout around the circumference relative to the center splines of the clutch driven disc. If it differs from the specified value, replace the clutch driven disc.
Limit runout/diameter of the measured section:
CR14 Motor: 1.0mm or less/When Dia. 180mm
HR Motor: 1.0mm or less/at dia. 190mm
Using a caliper, measure the distance from the rivet head to the surface of the friction lining of the disc. If it exceeds the permissible wear, replace the driven clutch disc.
Distance from rivet head to friction lining: 0.3 mm
Clutch housing
Check the unevenness of the diaphragm spring peaks with the lever inserted. If it is different from the norm, adjust the lever height using the diaphragm adjustment key (special tool).
Unevenness of the diaphragm spring peaks: 0.7 mm
Check the clutch housing thrust ring for wear or damage. Replace the clutch housing assembly if necessary.
Note:
- A worn thrust ring will make a ticking sound when the rivet is tapped with a hammer.
- A broken thrust ring will make a clinking sound when the housing is shaken.
- If you find any burn marks or discoloration on the contact surface between the clutch housing pressure plate and the driven clutch plate, remove them with emery cloth. If the surface is damaged or deformed, replace the entire component.
For more information, see the website: NISSANBOOK
Flywheel runout
Using an indicator, measure the flywheel runout on the clutch side. If the runout is different from the norm, replace the flywheel. If traces of burning or discoloration are found on the contact surface, remove them with emery cloth.
Note: Measure on the outer surface of the flywheel (where the indicator head does not contact the guide lug or mounting hole of the clutch housing).
Installation
1. Clean the drive shaft splines to remove grease and dust.
2. Apply the recommended lubricant to the clutch driven disc and drive shaft splines.
Note: The amount of grease is 0.4g. The application thickness is 1mm or less.
3. Insert the driven clutch disc onto the drive shaft. Remove any grease that comes out.
Caution: Excessive grease may cause slippage or shaking, and if it comes into contact with the CSC seal, it may cause brake fluid leakage. Wipe off excess grease.
Insufficient lubrication may cause knocking, incomplete disengagement or damage to the clutch.
4. Install the driven disc and clutch housing. Tighten the mounting bolts by hand and install the clutch centering mandrel (special tool).
Special tool number:
A: EM07020000 (cR engine)
A: KV30101000 (hR engine)
5. Tighten the clutch housing mounting bolts evenly in two passes in the sequence shown in the illustration.
Tightening torque (cR engine):
1st pass: 9.9-19 Nm (1.0-2.0 kg·m)
Final pass: 22-29 N·m (2.2-3.0 kg·m)
Tightening torque (hR engine):
1st pass: 19 Nm (2.0 kg·m)
Final pass: 22-29 N·m (2.2-3.0 kg·m)
6. Install the manual transmission on the car. See chapter Manual transmission.
