Lester Mags pre load

[140008]

1983 R100S W/Lester mags.How do you get the 2" chrome hub off it has 4 holes, looks like it maybe a spin off.I want to replace internal parts as the preload seems too tight and it is advised to install BMW guts.Wheel is about right w/ 10 lbs torque on axle nut. Any advice and direction would be appreciated.

Picture? Hole spacing? The old /2 bikes had a hub nut that has four holes...I bought a hub nut removal tool from Cycleworks...worked excellent. They list a tool for the /6/7 bikes, but no mention of Lester wheels.

Hub OD 55mm,Hub ID 36mm,Hole spacing center to center,opposing holes 44mm, 4 holes,5mm ea.So,these would have to come off to get 40mm bearing races in.

As it turns out, that hole spacing is exactly what my /2 hub nut removal tool is. I'd check with Cycleworks...what's the cost of a plane ticket to Alaska...

The Lesters that you have were PROBABLY set up for the /6 and similar configuration. The deal was that you would buy the Lesters, Transfer your bearings & other hardware (including the caps you speak of).

I believe that the 83 model has the newer style grease seal etc. Check the /6 parts diagram & see if that isn't what you have. the small cover with 5 bolts on the rear wheel bearing is also indicitive of a /6 type wheel.

Harbor freight used to have an adjustable pin spanner & probably still does.

Art,
You can make your own tool. 1/2 square key stock 2 1/2 inch long or so. Drill two 5mm (7/32 inch) holes spaced to match the holes at 180 degrees. Insert two 5mm x 20 mm lg bolts and nuts. Use a 1/2 inch open end to turn the tool.

Worked for me

Why not just work down the spacer with abrasive on plate glass to thin it a bit and increase the preload at spec torque??
