Clearance between the clutch drum and drive plates
Insert a drive plate (E) in the clutch drum (F) and measure the clearance (S) with a feeler gauge.
Clearance āSā must not exceed 0.6 mm.
If it does, renew the plates and, if necessary, the clutch drum.
Overhaul of the clutch plates
The clutch plates must not show any signs of blackening, grooves or deformation.
Measure the thickness of the drive (friction) plates; it should not be less than 2.6 mm.
Important
The total thickness of the discs pack must not be less than 46.1 mm.
Place the plate on a flat surface and check the amount of deformation with a feeler gauge.
Max. flatness error: 0.2 mm.
Overhaul of the pusher plate
Check bearing (6) conditions: replace the bearing if the play is excessive.
Check the contact surfaces of the last driven plate; if extremely scored, polish it in the same manner as described previously
for the cylinder head surface (Overhauling the head components).
Check conditions of the spring guide bucket tappets (G) of the pusher plate (4).
