Firstly because I'm fitting a belt drive and secondly this was a modification done by the factory in around 1951 on the 500. I'm fitting a seal and I need a seal holder. The seal holders I have are the genuine style. But, I have a back to back Timken Taper bearings fitted to the left side of the crank. Originally it has a ball bearing outer most ( which controls crank end float) and the other three crankshaft bearings are roller type. I show the area in the photos, along with my drilling guide and seal holder. I'm not going to use this seal holder as I want it to place some pressure against the taper bearing cup and come outwards from the bearing as well. As I have more clearance with the belt drive than I would if I where to use the original chain primary drive. And since I have 2 engine with this set up I'll be getting 2 made.
And for those that notice the orange square outline. This is a marking that is stamped into the cases. To check that they are a matched set. Very hard to see. But this unique marking is in the 2 crank halfs,primary cover ,G2 cover. I don't know what the stamping means. Maybe the bloke that assembles the engine has his own stamp?
Well this is as far as I've got. I''ll get some more pics up as I get more done. Off to lap the pushrods in.
Cheers

Hello Patrik,buellingvincent said:Hi, Working on three Vincent engines in parallel? Impressive! Good work indeed.
I will also install a pair of taper roller bearings in my Black Shadow and will omit the outer circlip as I also have a Bob Newby belt to be fitted. Thought I could use the standard seal holder from VOC Spares. Did you make your own?
Did you put the taper roller bearings in O or X arrangement? Could you advice how you came up with the width of the two distance pieces between the two bearings to get the right side play?

Well I have the Bob Newby belt drive out and measuring for new distance spacers and a new seal holder. I've been in contact with my machinist and he is up to speed. So its all go ahead.
then I need to make a new primary cover. I have seen some out of fiberglass ,but they look a bit ordinary. It needs to be alloy and polished. Anyone have one?
Well that means back to the timing side to finish of the push rods.
Have a great week
