Refitting The Clutch; Servicing The Clutch - MG MGA Twin Cam Workshop Manual

Turn the adjusting nuts until the finger just touches each release lever, pressing downwards on the
finger assembly to ensure that it is bearing squarely on the adaptor. Remove the finger and the pillar
and replace the actuator; operate the actuator several times. Re-check with the finger assembly and
make any necessary further adjustments.
Lock the adjusting nuts.
NOTE. —The clutch used on this vehicle differs from the normal 8" type and a special adaptor (Part
No. 18699B) must be used in conjunction with the gauge plate in place of the adaptor (code No. 6)
shown on the code card. The three spacers to be used with this adaptor are the same as those
indicated for use on the standard 8" clutch (code No. 2).

E.9 REFITTING THE CLUTCH
Position the driven plate assembly on the flywheel, taking care to place the larger-chamfered spline
end of the driven plate hub away from the flywheel.
Centralize the driven plate by means of the special alignment bar (Part No. 18G39) which fits the
splined bore of the driven plate hub and the pilot bearing in the flywheel. As an alternative a spare first
motion shaft can be used.
Locate the cover assembly on the flywheel dowels and secure with the bolts, tightening them a turn at
a time by diagonal selection. Do not remove the clutch alignment bar until all the bolts are securely
tightened.
Remove the clutch alignment bar and refit the gearbox. The weight of the gearbox must be supported
during refitting in order to avoid strain on the shaft and distortion or displacement of the release plate
or driven plate assembly.
E.10 SERVICING THE CLUTCH
As the clutch facings wear, the pressure plate moves closer to the flywheel face and the outer or
shorter ends of the release levers follow. This causes the inner or longer ends of the levers to travel
farther towards the gearbox. As the release bearing moves rearwards it must result in pushing the
piston in the clutch slave cylinder inwards. The piston then forces the excess fluid back into the master
cylinder via the compensating orifice.
Provided that the minimum 1/32 in. (.8 mm.) free movement is maintained between the clutch pedal
