It w ll now be necessary to turn to the left hand s de of the mach ne, and here w ll be seen the curved support
arm on the rear dr ve un t. Th s support arm must be removed before the un t can be taken out of the frame,
s nce t passes round the left-hand vert cal column of the frame.
Unscrew the three nuts at the rear of the curved arm wh ch secure t to the rear dr ve and remove the hollow
bolt at the front end of the curved support arm, (th s s the bolt wh ch also carr es a grease n pple). Take off
the large d ameter steel washer wh ch s pegged.
Now d sconnect the lower end of the rear suspens on damper un t, and sw ng the damper un t up and out of the way.
Ra se the rear dr ve and gently pr se off the curved support arm. L ft ng the rear dr ve un t w ll allow
suff c ent clearance for the support arm to pass over the p ll on passenger's footboard.
The three bolts wh ch secure the rear end of the support arm should now be taken away s nce they are
l able to foul the frame as the un t s be ng removed.
Remove the rear mudguard by tak ng out the four 1/4 n. d ameter nuts and bolts, two at the front on
the cross member between the two vert cal tubes of the frame and two at the rear wh ch also carry the

D sconnect the generator cables by break ng the connectors wh ch w ll be found underneath the
floorboards. Th s operat on w ll be eas er to carry out f each connector s broken nd v dually.
The un t s now ready to be taken out of the frame, and t s qu te easy to do so prov d ng the correct
procedure s adopted, wh ch s to dr ve out the two bolts hold ng the eng ne to the vert cal frame tubes, t lt
the un t forward so that the lugs on the eng ne clear the lugs on the frame and then t lt t s deways
towards the left-hand s de, at the same t me l ft ng t out. Th s w ll enable the rear dr ve to pass between
the two vert cal tubes.(Caut on to do ng yourself an njury through th s as t s awkward and heavy)
