Default Old STF VL neck cups

Anyone else running these? Can i just sit them right on the bearing race built into the neck stem or do i need to make a spacer for them to rest on? First build, lots of second guessing, thanks!

The old ball bearing race has to come off so that the new bearing seats properly.
The Timken bearing that fits the 1.125" VL stem and a standard Big Twin neck cup is part No. L44459 for anybody who is interested.

Yes they are pressed on which was standard Harley practice also on the Timken bearings. To remove use either heat or mechanical destruction like cutting with a dremel or grinder. Make sure not to nick the stem.

If you hit them with a little weld won't they just fall out?

I have an argument with someone about the VL stem.
I keep telling the guy OEM is 1"1/8 fixed stem and he keeps on telling me some VL front end had 1" removable stem from the factory, because he has one like this so he thinks it's oem...

Has anybody a document (part or service manual, harley history book...) stating the fact? Something that will look like official information because I'd like to close the argument with the guy and prove him he's wrong, but he's very stubborn...

(sorry Fredo for the hijack)

Vins,
The guy selling that I-beam front end is totally wrong about the the 1" stem.

NO Harley I-beam front end had a 1" stem or a removable stem.

For verification, Palmer's book is about as reliable a source as you'll find. Tell him to check out page 94 in the second edition volume one under the heading "I-Beam Springer Forks".

Geo.

Yes Geo I know he's 200% wrong, but you know how it is when it turns to an argument...
Off course he wants to believe his front end is original, this way it has more value

I thought Palmer was only covering from 1936, do you have a way to scan that page 94 and post it here (or send me by email) ?
Or if you have no scanner, maybe a good pic will do the trick...

Thanks

Vins, the polish made for a dutch company VL frontends sold by W&W have a fixed 1" stem. They have been around for 20 years. Maybe one looks old enough to "be original" ?
The stem on those is also not the 1" springer type stem but resembles one of a timken bearing glide.

I see what you mean, but the one this guy have has a removable 1" stem...
Making it even not original from W&W...

Maybe early model when they wanted to offer 1" and 1.125" stems? That would make sense. The Dutch guy was into restoration and found out later that there is a so much bigger market in the custom/chopper field.

Vins,
From the pictures I saw, that is definitely a VL I-beam springer, but the original stem was removed and replaced with that fabricated bolt on stem. He is right about the frontend, but wrong about the stem. The upper portion (above the yolk that joins the two legs) is much different on the European I-beams - more like a conventional tubular Harley springer than the Harley I-beams.

Geo.

Nothing wrong with your computer, I didn't post any pictures.
Geo saw them on PM....

Anyway, if someone can post up or send me the Palmer's book page 94 in the second edition volume one that would help me big time.

Thanks
