Now take out the four small Phillips-head screws
securing the generator cover, and remove the cover.
To remove the inner cover, first take out the one
Phillips-head screw at the back, then unscrew the three
generator cover stator nuts. Tap the cover gently
around its edges to release, and withdraw the cover
complete with stator. Take care not to loose the three
small spacers that are located on the fixing studs
between the stator and inner cover. The inner cover
carries the clutch actuating lever and adjuster. If this
mechanism requires attention, unclip the return spring,
unscrew the adjuster locknut and press the lever out of
its bush. The push rod ball is loosely located in the
lever boss. Withdraw the push rod and rubber sleeve.
The gearbox sprocket is held to thee sleeve pinion
by one large left-hand threaded nut, and a tab-washer.
Flatten the washer, and locking the sprocket with a
length of chain, unscrew the nut.
Pass a length of bar through the small-end bearing,
and, taking care not to damage the crankcase top joint
face, turn the engine until it is locked solid.

ENGINE
The generator rotor is secured to the keyed engine
shaft by one large nut and spring washer. Undo this,
pull off the rotor and extract the Woodruff key from
the shaft.
Using the same method remove the self-locking nut
securing the engine sprocket. Remove the chain by
releasing the spring link and threading it out.

CLUTCH PLATE DISMANTLING

Take off the clutch cover plate, retained by three
small screws with spring washers. Now, using service
tool No. 61-319 (as shown in B9) compress the clutch
springs to allow the large plate retaining circlip to be
removed.
Remove the tool, and lift off, and lift off the
retaining plate complete with springs and cups. The
pressure plate, and friction plates can now be taken out
for inspection. Take care not to loose the mushroom-
headed push rod which fits in the end of the mainshaft.
If the clutch plates or springs are the only items
requiring attention the clutch not be dismantled any
further.
