Service Sheet No. 1003 (contd.)
Make sure that the petrol tap is turned off and uncouple the banjo union at the carburetter end of the
petrol pipe. Be careful not to lose the two fibre washers or the small gauze filter which is fitted inside the banjo
union.
The petrol tap rod is supported by a bracket which is secured to the nearside rocker cover stud; remove the 4
¼ inch nut on its stud lift the bracket off the stud and swing it to one side. Replace the nut loosely on the
stud to retain the fibre and steel washers.
On the right-hand side of the machine will be seen the gearchange lever, fitted to the quadrant spindle; take
off the nut securing the lever to the spindle end and prise the lever off the squared end of the spindle.
Now depress the kickstarter lever and disconnect the chain from the lever by removing the spring
link.
The kickstarter sprocket and the chain can be removed after the unit has been taken out of the frame,
but the sprocket can be removed at this stage if necessary, it is fitted on to a taper shaft which is keyed.
Remove the nut securing the sprocket, and with an open-ended spanner behind the sprocket and against
the adjacent Phillips head screw, tap the end of the spanner sharply so as to jerk the sprocket from the
taper on the shaft.
Disconnect the speedometer drive from the rear hub by unscrewing the union nut (Fig. 3). The
speedometer drive cable is the upper of the two cables which run to the rear wheel, the lower one
being the brake cable. Also disconnect the rear brake cable by taking out the split pin and clevis
pin which secure the cable end to the brake lever on the rear hub.
Remove the two black and yellow wires which run from the distributor to the left-hand and right-
hand ignition coils by taking off the two nuts on top of the coils. Note that the longer of the two
cables (black and yellow) goes to the right-hand coil.
With a suitable tool such as a screwdriver or a hammer shaft, press in the clutch lever on the
engine, slip the nipple out of the lever, pull the outer casing out of the lug and place the spring on
one side. Push the cable down under the frame out of the way.
It will now be necessary to turn to the left hand side of the machine, and here will be seen the curved support
arm on the rear drive unit. This support arm must be removed before the unit can be taken out of the frame,
since it passes round the left-hand vertical column of the frame.
Unscrew the three nuts at the rear of the curved arm which secure it to the rear drive and remove the hollow
bolt at the front end of the curved support arm, (this is the bolt which also carries a grease nipple). Take off
the large diameter steel washer which is pegged.
Now disconnect the lower end of the rear suspension damper unit, and swing the damper unit up and out of the way.
Raise the rear drive and gently prise off the curved support arm. Lifting the rear drive unit will allow
sufficient clearance for the support arm to pass over the pillion passenger's footboard.
The three bolts which secure the rear end of the support arm should now be taken away since they are
liable to foul the frame as the unit is being removed.
Remove the rear mudguard by taking out the four 1/4 in. diameter nuts and bolts, two at the front on
the cross member between the two vertical tubes of the frame and two at the rear which also carry the
silencer and petrol tank support bracket.
Unscrew the two 3/8 in. nuts on the bolts attaching the engine unit to the two vertical frame tubes at
the rear of the frame. On the left-hand tube it will also be necessary to take out the two 1/4 in. bolts securing
the quarter portion of the clip. Drive the bolts partially through but still allow them to support the engine.
Now remove the front engine plates by taking off the nuts on the two crankcase studs and remove the two
5/16 in. bolts and nuts which secure the "L" shaped engine plates to the chassis cross member. When the
bolts securing the plates to the cross member have been removed slide the plates off to left and right from
the studs. The engine will now be supported only by the two 3/8 in. bolts through the rear brackets.
Disconnect the generator cables by breaking the connectors which will be found underneath the
floorboards. This operation will be easier to carry out if each connector is broken individually.
The unit is now ready to be taken out of the frame, and it is quite easy to do so providing the correct
procedure is adopted, which is to drive out the two bolts holding the engine to the vertical frame tubes, tilt
the unit forward so that the lugs on the engine clear the lugs on the frame and then tilt it sideways
towards the left-hand side, at the same time lifting it out. This will enable the rear drive to pass between
the two vertical tubes. (Caution to doing yourself an injury through this as it is awkward and heavy)
Complete dismantling of the engine, gearbox and final drive unit is described on Service Sheet No. 1004.
