Assembly Part 1

This part will deal with the assembly of the main lower castings the main bearings and associated parts together with the cranks gear, spacers and the sundry other small parts.

The fitting of the crank and main bearings. Photo show the final touches to the tapping of the main bearing for their oil caps. These must be tapper right through and the oil cup made to fully engage into the bearing to prevent any rotation in the Aluminium castings parts.

Before fitting the main bearings make sure that any burrs have been removed.

When fitting the bearings to the crank make sure there is oil on the inside and not on the outside.

Ensure that the bearing cap is a nice fit, that bearings are the right way round and that the crank can rotate.

Place a washer under on each stud and put on the M6 nuts and tighten down evenly.

The crank shaft should be found to be free to rotate. if this is not the case investigate fully and remedy.

Locknut down by tightening the top spanner on the top nut against the lower spanner on the lower nut.

Place the large spacers on the gear side of the engine followed by the gear which is locked into place by a small piece of key way.
