I have a collection of worn .031" thick E76, they all wornHello Highbury, Some thing is going wrong here, E76 goes between G6 and the bearing in G2, It is held tight when you do up the clutch nut C20, Spin often happens and E76 wears, and sometimes breaks up, I have found 31 thou one is most used, At the other end you could grind a few Vs on the inner end of G4 ,To let the oil get to the G16 and G17, But Trev will tell you it will leak oil !, Or you could put Trev's Special grease inside G4, It is good !! to have some Lube in there !! Good Luck. If I have got this wrong !! Shout out !, Because Highbury needs help, Cheers Bill.
, some more than others. consequently I would not entertain using such a thin shim in that position, for any thing wearing to the point of failure, and dropping into the gear box is to be avoided, what you possibly need is a hardened shim, but where you could get one from I do not Know. Possibly Trevor could help.
Having said that , my twin is running O.K. with a standard .031" thick E76 as are many, many more Twins.
