Earlier we trial fitted the crank pinions to check out primary drive alignment & ensure the cam, intermediate gears & oil pump/points gear rotated freely & could be timed up.
Now we can fix it all up permanently.
Fit the first crank gear its key, lockwasher & nut with a drop of Loctite on the thread & lock it up.
Time the oil pump/points gear to the crank gear and secure it with a split pin. Slide on the “double gear” (gear /sprocket combo if you are on chain drive).
Fit the second crank gear & mesh with the clutch. I use a Belleville washer behind the nut and a drop of Loctite to retain it.
The cam & intermediate gear can be put in place now & timed up. The OE gears are marked up but its always good to check the timing with a degree disc & make sure all is well.
I have a cutaway dummy outer cover which was given to me years ago by PJ in the USA. A very handy bit of kit which allows timing to be checked without fitting the full cover. Thanks PJ!
In case anyone thinks a good cover was sacrificed to make this it was scrapped by the original owner who had it chrome plated!
No doubt his engine didn’t appreciate the acids used eating away the cast-in steel oil feed tube to the crank, cam, its drive & rocker gear.
