springer question

#1

Post by old52pan » Tue Jul 21, 2009 9:11 pm

Doe's anyone know if there is suppose to be a convex self centering bushing on the lower stem of an offsett big twin springer? I drove the lower bearing on after heating to 450 degrees in the oven and this bushing seems to hold the bearing up a bit to high. Any thoughts would be appreciated. Thanks-panman1960

Dear panman1960,

Is that a timken? They gotta be cut for a springer.

That centering thing is for loose ball bearings. It would probably need to be machined off to run Timken style bearings. Is this a factory springer ? There's really nothing wrong with loose ball bearings.

it's an v-twin repro, anyone running timkins on their springer know the answer before I permanantly remove the centering spacer?

Dear Panman1960,
All bets are off on a repop.

If it was a real one, then the bottom timkens gotta be bored a smidge with a reeaaly good carbide, because the stem has a step that doesn't match metrics.
Youll split it if you try to press it on I guarantee.

So it takes two different bearings. Maybe they make them now.

And save the little domed shim for someone else passing by the other way.

The V-Twin springers have the centering bushing/shim thing installed at the base of the neck. If you tried to press on a timken style bearing it would prevent the bearing from seating down all the way on the neck stem. I would think "it' would need to be removed for your application.

What do you mean all bets are off on a repop fork? Since these were first produced 18 or 19 years ago, almost 20,000 have been sold!! I offer a lifetime warranty on them if you buy from me.

I "do not" recommend Timken bearings at all for this application, yet people still feel they need to use them. If you have to, you need to remove the bevel washer at the base of the fork stem. It does come off without cutting it. You will also need a special fork stem nut....if yours didn't already come with it....designed for the Timken. The beveled edge on the nut needs to be milled flat to sit on the Timken correctly.

Problems you may/will encounter: The Timken stack is too high and the handlebars won't fit correctly. By that I mean the center nut will not start...or will barely grab. I've only seen one set of Timkens made for a springer that works......but I don't recall where it was from.

Hi Kurt, I ordered a springer timken fork conversion kit from v-twin recently. I sure hope I don't have a top tree issue.It does come with new cups and what looks like a very short cone nut. I will post the progress as soon as It arrives. panman1960

I'm fairly sure that's the one that doesn't fit. The cups are too tall........
