REMOVING CYLINDER AND PISTONS
|
|
|
|
Remove the cylinder head as detailed in Section
C1. The cylinder is then removed as follows:
|
|
|
|
1
|
Remove the nine cylinder base nuts - to do so,
it will be necessary to raise the cylinder slightly
to allow the nuts to be removed completely trom the
studs. All the nuts have washers excepting the
front centre one. Take particular care that all the
nuts and washers are removed before the cylinder is
lifted.
|
|
|
|
At this stage the engine may be decarbonized as
in Section C4 or the cylinder, pistons and piston
rings given attention.
|
|
|
|

|
Commence lifting the cylinder off the base studs
and prepare to support the connecting rods as the
cylinder is lifted clear of the pistons. In Fig.
C10 a suitable implement has been inserted between
the studs to prevent the connecting rods and
pistons falling against the crankcase mouth. Any
damage to the connecting rods couid result in
failure of the rods at a later stage of use.
|
|
|
|
3
|
Place a piece of clean non-fluffy cloth over the
crankcase mouth to prevent foreign matter entering
the crankcase mouth.
|
|
|
|
4
|
Remove one circlip from each wrist pin (gudgeon
pin).
|
|
|
|
5
|
Before removing the piston, support the body
(Fig. C11 ) shows the piston body being supported
by a second operative) and push out the first wrist
(gudgeon) pin, then the second, using a suitable
sized implement such as an aluminium drift.
