Oil seals

Unread post by arsey30 » Fri Jan 13, 2012 11:38 pm

Has anyone tried fitting [with suitable machining] oil seals, either O rings, square edge or sprung lip seals to the gearbox gear lever and/or kick start shafts?

Mine weeps a little oil [B175] whilst the rest of the motor is oil tight.

A small leak never worrried me so I never had reason to do such a mod.

However it would be easy to do if you have access to a milling machine.

My old Triumph Tiger 90 had "O" ring seals on the kickstart and gear lever shafts as standard.

My AJS had O rings on the shafts, but square edged ones worked better.

I thought if the mod had been done I could note down those machining dimensions and seal types and sizes.

This site shows how to calculate groove size for O rings.
