4.5.10 Crankshaft Gear
Once the engine mount plate has been removed the crankshaft gear can be removed from the end of
the crankshaft. Using 2 large screwdrivers, lay one across the end of the crankcase to protect the
surface and use the other to lever the gear off as shown below left, working from side to side.
Figure 52
– Removing Crankshaft Timing Gear & Dowels
Extract the 3 dowels from the end of the crankshaft
– use a suitable collet type extractor (a
commercially available tool) that has a straight pull as shown above right. It may be necessary to heat
the end of the crankshaft slightly to extract the dowels.
4.5.11 Cylinders
Figure 53
– Remove Cylinders
Undo the base nuts from each cylinder pair until one nut can be removed from the cylinder stud and
then pull each cylinder off of the piston as shown in Figure 53. Note that these through bolts and studs
are normally replaced at overhaul
– see Section 5 for details.
Some of the cylinder studs will come away with the cylinders: clamp these studs carefully in the padded
jaws of a vice and remove the remaining base nuts from the studs.
