J&P Cycles has Timken style bearings for the early Sportster. Or you can go to your local independent motorcycle shop and get them. Made by the V-Twin, etc motorcycle suppliers.

NOTE: Some of these kits specify the cups come with 'TIMKEN TYPE' bearings but are not actual 'Timken' bearings. Whatever bearing comes with the cup set, you can take the bearings number and go down to your local Bearing Supply house and cross referance the number and get real 'Timken' bearings.

Does anyone have any part number or cross refrence harley models for neck cups and bearings using a Wide glide front end with a 1" stem on a 76 sportster with 7/8" original setup. I checked JP cycles and they have cups for timkens that covert old ball bearing necks to timken bearings but I think this is still for 7/8" stems. There is a 41mm kit in the front of the book that refrences a V-twin part # of 24-0157 which is not a part # in the V-twin book. Thanks in Advance.

Years ago, the absolute best way to convert a Sportster front end to the Wide Glide, was to use a Servi-car tripple tree. The Servi-car was equiped with a Wide Glide front end. The same front end as her big brothers. The only difference is the stem diameter. All the WL models used a 7/8" stem. Even the WL springer is a direct bolt on for the 7/8" neck Sportster models. If you could just find the lower tree, the rest is simple. All of the other 49mm Wide Glide parts will work with the Servi-car lower tree. They are pretty simple to spot. They have a 7/8" stem. Happy hunting.-Joe

When I converted my Marzocchi forks, I had the same problem. I turned the stem down to 1", and bought the standard timken conversion cups. The I turned the I.d. of the cups to clear the stem. Then I bought B/T bearings and viola! It fits! I don't know of any other way. If someone came to me with cups and wanted them turned down on my lathe I'd probably do it for 10-20 bucks, or free if they were a regular customer. I imagine you could use a die grinder if it's all you can get, but the cups end up kinda thinish, I'd much prefer a precision cut.

Obviously you won't need to turn the stem down!

I put a 99 fx front end on my 77 and converted to 1" neck, timken bearings and it had an internal fork stop set up . . .was only about $40 for the complete set up on ebay in stainless. Had to machine the lower outers of the cups to suit my frame and cut 1/2" from the length of the main 1" pivot bolt

BTW, I thought all of the servicars ran adjustable rake trees? I'm not certain, I just thought so. My buddy had a '73, and his had adjustables.

I am in the process of converting my 77 ironhead stock front end to 41mm wide glide. is it as simple as pulling my forks from the stock trees and sliding them into the new 41mm wide glide trees. I have read the other replys here on the subject but no one spells out an exact/precise step by step procedure.
Does anybody know of a sure bet bolt on set up? is there such an animal??

I used a set of cups from billetwerx http://www.billetwerx.com/products.php
Remove old cups put these in with new bearings. BTW 1" trailer axle bearings work great and are easy and cheap to get.
