Liner protrusion

Fit the clutch mechanism, fig. I.

Tighten the bolts (fitted with new locking washers) to a torque of 1.5 m.daN (15 Nm, 11 lbf ft).

Fit the liners, fig. II, without their seals, positioning the flats as shown in the illustration.

IMPORTANT - Ensure that the pistons and liners are retained in their original matched assemblies.

Zero the dial indicator on the cylinder block, fig. III and measure the height of each of the liners at points (A), (B), (C) and (D) as shown in fig. IV.

NOTE the highest liner protrusion.

The maximum difference between (A), (B), (C) and (D) should be less than 0.07 mm.

If the difference is greater than 0.07 mm.

Look for the cause and if necessary change the position occupied by the liner.

Mark the liners 1 to 4, fig. V.

Liner protrusion

Select a seal so that the liner protrusion, at the highest point, is between 0.07 and 0.14 mm, as near 0.14 mm as possible :

Liner seals

paper and white synthetic fibre → 07/85, steel plated with aluminium.

IMPORTANT - Use only one seal per liner.
