Please note:
I f you wish to carry out the above mentioned repair work, do
not remove the engine; just proceed as per page 9, "Dismantling
and Reassembling of Engine", paragraphs 1, 4, 5 and 6. (However,
please bear in mind that this applies only to the above
repair work!):
1. Undo the nuts on the cylinder head cover with box spanner
( SW 10), remove air-vent hose and cylinder head cover. Remove
cooling baffles, dismantle induction and exhaust manifolds.
2. Unsrew and remove spark plug. Place piston at t.d.c. with valves
closed and loosen clamp nuts 7.1 and nuts for rocker arm shafts.
Cover push rod channel with clean rag. Undo two nuts (SW 10)
on rocker arm and slightly loosen the ball-shaped screw for
valve setting, so that the rocker arm shafts 7/2 can be pushed
out of their Journals with a pin without forcing.
Take off rockers 7/3 (and the spacing washers) and remove push
rods.
3. Using box spanner (SW 14), undo cylinder head fixing nuts 7/4
and take off cylinder head and cylinder. (Watch out for the softi
ron washers, since these have to be used again when reassembling).
4. For better dismantling of the piston, use the forked retainer plate
(401/W 20) 8/1. Cover crank case with a piece of clean rag.
With a pair of pointed pliers, remove both wire snap rings from
the piston. Push out the piston gudgeon pin with gudgeon pin
extractor (401/W 26) 8/2 and remove piston.
Please note:
To avoid bending the connecting rod, on no account knock the
gudgeon pin out.
5. To strip the engine completely, undo nuts 7/5 and take off the
bracket.
