Close Mr.Pete but doesn't take into account the fact that if there are two ways to fit a component somebody will fit it arse about
As I don't have a manual for a two bearing engine, only for a bush and bearing engine, I simply refitted everything as it came apart.
Now the clamping washer has a bevel on one side and that had been fitted towards the bearing and the flat side towards the pinion so that's how I re-fitted it which was allowing the crank to walk in the bearing as the bevel allowed the nut to clamp the pinion but not the bearing to the crank so then all that limited the end thrust was the distance between the crank shoulders and the bearing inner races which is 31 thou or 0.8mm
So I've ordered 0.7mm worth of shims for the drive side of the crank which will set things to spec.
The crank slides easily in the inner races so a lick of loctite there will do no harm on reassembly as well.
With the timing side clamped the rods are nicely central in the bores
as well so no drama there.
Thanks to everyone who chipped in with advice on this one.
