We remove the clutch discs for inspection, repair or replacement

Removing the clutch discs

Remove the manual transmission

Remove the cover of the clutch release fork

Remove the clutch release fork assembly

Remove the clutch release bearing clutch clamp

Remove the clutch release fork support from the gearbox

Apply mounting marks on the clutch cover and flywheel

We unscrew each bolt at one time for one turn, until the spring force is weakened

Clutch cover removal: A - mounting marks

Unscrew the clutch cover bolts

Remove the slave and master disks

Clutch test

Use a vacuum cleaner or a clean cloth to remove dust from the clutch cover

Check the condition of the friction surface of the flywheel for cracks, burn marks and surface wear

Check the condition of the friction linings of the clutch driven disk and if they have traces of oil or mechanical damage, replace the driven disk

Measuring the friction linings of the driven disc

Check the thickness of the clutch disc lining using a vernier caliper.

The overlays must protrude above the heads of the rivets by at least 0.3 mm

If the thickness of the pads is less than acceptable or the rivet heads are close to the working surface, replace them or the clutch disc.

Check that the springs are not broken or cracked.

Check for wear on the splines in the hub of the clutch disc

Mounting the clutch disc to the gearbox shaft

Install the clutch disc on the gearbox shaft

The clutch disc should slide easily and smoothly on the splines of the input shaft of the gearbox

If you need to replace the driven disk, then you must also replace the clutch release bearing

Using a dial indicator, check the runout of the clutch disc

Minimum runout 0.8 mm

Measuring the depth and width of the diaphragm spring blades

Using a vernier caliper, we check the depth and width of the wear of the petals of the diaphragm spring

Maximum:

  • A (depth): 0.5 mm;
  • H (width): 6.0 mm

Slight damage to the friction surface can be removed with fine sandpaper

Measuring flywheel runout

Using a dial gauge to check flywheel runout

Maximum runout - 0.1 mm

Checking the clutch release bearing

Checking the clutch release bearing

We rotate the clutch release bearing by hand, applying force in the axial direction, we check the release bearing

The bearing is lubricated for life, no additional lubrication is required

Installing clutch discs

Mounting the clutch disc on the flywheel: A - side facing the flywheel; B - special tool (guide mandrel)

We insert the special tool into the clutch disc, then install the disc on the flywheel

Align the mounting marks on the clutch cover and flywheel.

The order of tightening the clutch cover bolts: A - mounting marks; B - special tool (for example mandrel)

We tighten six bolts, starting with the bolt located near the pin on top.

Acting in the order shown in the figure, at the same time evenly tighten the bolts. Tightening torque 19.1 Nm

Checking Diaphragm Spring Leaf Alignment

Using a dial indicator with a roller, check the alignment of the diaphragm spring petals

Maximum mismatch is 0.5 mm

Install the clutch release fork support into the gearbox. Tightening torque - 47.1 Nm

Install the clamp of the clutch release bearing on the bearing

Fork grease, pushrods and fork support points

Apply grease to the contact surfaces of the clutch and the clutch release fork, the fork and pushrod and the fulcrum of the fork

Applying grease to the splines of the clutch and to the splines of the input shaft

Lubricant: P/N 08887-01806 Clutch Release Grease or equivalent

Installing the clutch release fork with the clutch release bearing into the gearbox

After installation, move the fork back and forth to check the smooth movement of the release bearing

Installing the cover of the clutch release fork
