Installation
7 Installation is the reverse of removal. Apply
a smear of grease to each end of the pinion
shaft, then install the pinion assembly,
ensuring the inner pinion engages with the
starter motor shaft (see illustration).

are fitted with a cable operated pump; all
other models are fitted with a centrifugal
pump. A quick visual check will confirm which
pump is fitted to your machine.

Removal
1 Remove the exhaust system (see Chapter 4).
2 On models fitted with a cable operated
pump, detach the cable from the pump pulley
(see illustration), then unscrew the bolts
securing the cable bracket and remove the
bracket with the cable attached (see
illustration 5.10). Note: Early
50
cc models
were fitted with a Keihin oil pump which is
retained by a single bolt.
3 On all models, release the clip securing the
oil inlet hose from the oil tank to the union on
the pump and detach the hose (see
illustration). Clamp the hose and secure it in
an upright position to minimise oil loss.
Release the clip securing the oil outlet hose to
the union on the pump and detach the hose.
Wrap clean plastic bags around the hose
ends to prevent dirt entering the system.
Note: The inlet and outlet hoses are protected
from the exhaust pipe by a heat-proof sheath.
Remove the sheath i f necessary but don't
forget to refit i t on reassembly.
4 On models fitted with a centrifugal pump
(without cable operation), unscrew the pump
mounting bolts and remove the bolts.
5 Withdraw the pump from the crankcase and
remove the wave washer (see illustration).
Note how the tab on the back of the pump
locates in the slot in the pump drive shaft.
4 Check the starter pinion assembly for any
signs of damage or wear, particularly for
chipped or broken teeth on either of the
pinions
(see
illustration).
Check the
corresponding teeth on the starter motor
pinion and the starter driven gear.
5 Rotate the outer pinion and check that it
moves smoothly up and down the shaft, and
that it returns easily to its rest position.
6 The starter pinion assembly is supplied as a
complete unit; if any of the component parts
is worn or damaged, the unit will have to be
replaced with a new one.
