Thanks for that, Ron. I have, in fact fitted a sealed bearing, and it doesn't leak on the bench. Interestingly, there seem to be 2 types of rubber sealed bearings... Contact and Non Contact.
With LLB type bearing, the seal does not contact the inner race, but with the LLU bearing, it does.
Unfortunately, I've become interested in how the original design worked. (sort of).
I've checked the size of my washer, and it's exactly the same size as given in Neale Gentner's tips.
I don't know if you agree with my suggestion that the washer rubs on the bearing, but if so, I imagine it would be essential to omit the outer washer, otherwise the seal will be damaged by the filings? After all, it won't make any difference to mainshat endfloat.
(Later the same day...) I've just taken some measurements, and see that the washer OD is only 0.015" larger than the ID of the outer race (so, 0.0075" larger on diameter).
I've also looked at some old bearings and washers, and it seems that in use, the bearing only polishes the washer and doesn't grind it away.
Next question,can anyone confirm that the oil flinger washer 24-4235 at the kickstart end of the mainshaft, fits with the large diameter flinger part (and lip) against the mainshaft 1st gear?
Ron,
Thanks for the diagram.
There is no recess in my oil flinger washer. However, the outer diameter is curved over.
I think it fits with the curve towards the inside of the gearbox, next to mainshaft 1st gear. What do you reckon?
