Maintenance Manual and Instruction Book, 16H, Big 4, 18 and ES2

Smear the two edges of the case with gold- size or jointing compound. Fit wheels into the case and tighten all bolts and nuts. If the valve stem lubricator (S.V. engines only) has been removed from the timing side of the case, re-fit. Screw lubricator into case, and when tight the oil holes should point towards the valve stems and the bevelled side should face the cylinder barrel. Fit timing gears (para. 29), and panel (para. 26). 39. FITTING ENGINE TO FRAME. Fitting of the engine to the frame should present no difficulty. Lift engine into cradle and insert the two cradle bolts. Starting at rear engine plates fit all bolts loosely, working finally to the front engine plate bolt. Tighten all nuts. Fit clutch, oil bath, etc. Fit and time magdyno. 40. REMOVING AND FITTING OF TIMING GEAR BUSHES. When engine is dismantled it may be found that the timing gear bushes require replacement. This is not a job to be under­ taken by the average owner. The timing cover and half crankcase should be despatched to our service department.

38. ASSEMBLY OF CRANKCASE. Fit flywheels into case, and fit and tighten all bolts. Test for side float in the flywheels, there should be .005". If the float is excessive, remove wheels from case. Fit pen steel washers to the engine and timing shafts to take up the excess of float. Fit the same thickness of washers on each shaft, keeping the wheels central in the case. Check side float. If the side float is correct, check connecting rod for being central in case. There is side float in the big-end. Place fingers on the bottom of the connect­ ing rod and push rod towards the timing side of the case. Measure the distance from the end of the small-end bush to the side of the crankcase mouth on the timing side. Push rod to driving side of case and take the same measurement, from the driving side. The two measurements should be within 1/64" of each other. Rod can be lined up by transferring the pen steel washers on the driving and timing shafts to whichever side needs them, to obtain the correct alignment. When the correct alignment is obtained, remove wheels from case. Lubricate main bearings and big-end.
