4.5.12 Pistons
Figure 54
– Remove Pistons
Use 2 small blade screwdrivers to lever out the top gudgeon circlip from each piston as shown in Figure
54. (round type clip shown
– use std circlip pliers for circlips with eyes) Now, working on one piston at a
time, support the top of the piston against the side load as shown above right and carefully extract the
gudgeon pin out of the piston.
Remove the piston from the connecting rod. Take care not to put any side load on the connecting rods
while removing the gudgeon pins. A suitable soft drift may also be used to carefully drive the pins out.
4.5.13 Front Seal & Oil Pump Housings
Figure 55
– Front Seal & Oil Pump Removal
Before the crankcase can be split the screws holding the front crankshaft seal and the oil pump housing
must be removed. The cap screws holding each must be removed. The oil pump and housing can be
removed completely (a soft hammer may be necessary to break the seal of the housing from the
crankcase). The seal housing cannot be removed completely at this stage but it should be freed from
the crankcase (again, a soft hammer may be necessary).
