- To center the driven disk, a centering rod is usually required. For this, you can use the existing clutch shaft, which you may have in your workshop. Keep in mind that not all engines have the same clutch shafts.
- If there is no clutch shaft, you can straighten the driven disk using a rod whose outer diameter matches the inner diameter of the splines. On this rod, grind a neck that has a diameter equal to the inner diameter of the crankshaft guide bearing. In skilled hands, you can align the driven disk by eye. When installing the driven disk, place the long side of the clutch disk hub outward, that is, toward the gearbox.
- Before installing the clutch, lightly lubricate the splined portion of the clutch shaft. If the clutch is being reinstalled, position the clutch according to the marks made during removal and install it on the flywheel.
- Tighten the clutch bolts crosswise in several passes to a final tightening torque of 20 Nm, removing and inserting the centering rod (or shaft) as shown in Fig. 160 to check the ability to move along the splines.
