## Engine/Primary Transmission

# C

12 | For convenience, remove the engine sprocket puller from the sprocket and lift away the remainder of the clutch, the engine sprocket and primary chain as a set as shown in Fig. C16, feeding the stator between the runs of the primary chain.
13 | It will be noted that clutch and engine sprocket alignment has been ensured by the use of a collar and spacers over the gearbox mainshaft and these items should be collected and stored carefully for use during re-assembly. Note that if the crankshaft, engine sprocket, mainshaft or clutch have been renewed, re-alignment may be necessary.
14 | In order to remove the inner primary chaincase the three set screws with tab washers should be removed. Before attempting removal, tap the tabs clear of the set screw heads, remove the set screws then the tab washers and lift clear the inner primary chaincase. The chaincase may be removed with or without the stator, whichever is desired. The stator is secured to the chaincase at this stage only by the main cable passing through the grommet in the back of the chaincase.

15 | Collect the spacer washer or washers used on the centre stud. Note that if a sufficient quantity of oil has drained into the crankcase prior to stripping, oil will tend to run from the chaincase securing holes in the crankcase, thus it is recommended that the bolts be replaced finger tight in the lower holes.
