Trying to fit my layshaft and I'm worried I have the wrong type for my series iii

I cant push it through the bearing far enough for the puller to engage. It gets as far as the bearing face where the o seal sits

What do you reckon?

I would take the o ring out and try and fit the bearing just to check something really weird isn't happening - otherwise is it the right o ring and is there more than 1 in there - should be okay with some rubber grease if all is okay.

Use the cone and hub nut to pull the layshaft through the bearing.

Good suggestion about the o ring but it does not even get that far, none of the bearing face will go through the bearing

I'm pretty sure that the bearing is right as its from SR, so that leaves it as a bad layshaft. I'm hoping that someone will say something like 'the series two shaft had a wider bearing face' so at least I can resell it rather than throw it in the bin

Its a new shaft of Indian extraction I bought off ebay about 8 years ago, pre learning my lesson regarding buying stuff off there.

I have a horrible feelin I will be posting in the wanted section soon..

I dont have a hub and cone but I guess that would have the same issue as the puller?

Do you have anyone close by who could lend you a lay shaft to try or measure ?

I'm puzzed as to why you have the seal retaining plates fitted before the layshaft is in !!
Are you sure you have the correct hub bearing? It is a unique one.

I had an MRB layshaft that was the same as this, really tight in the bearing.

Series 2 layshafts are just thicker around where the cursor runs, heavier but I like them for supporting the cursor better.

Lots of patience, shims and pulling through with the nut. Maybe freeze the layshaft to give a nats more clearance is the only mad brainwave I can come up with.

Your OK with the retaining plates, if you put pressure on the bearing without these it could move or come out if its a little loose.

Remember to walkaway before you take a hammer to it!

That's the order that its described in which to do it in Sticky's book. The bearing could be wrong however its from Scooter Restorations so I'm pretty confident its correct.
