Head / barrel oilway o-ring
Posted: Fri Feb 11, 2022 6:17 pm
Just coming up to 100km since motor rebuild and a lube oil leak has appeared at the top of the barrel.
The o-ring came in a kit from a reputable supplier (although the left side cover gasket was a poor fit so I made my own).
I can order another but the ratio of postage to item is ridiculous (30:1) and I don't want another failure. I recognise that it could be an assembly fault on my part and will assess at strip-down.
There is a good hydraulic parts shop nearby. But what to order: the Mototrans narrowcase part dimensions are 7.66 x 1.78 mm and online parts supply either don't list sizes or list as 8mm.
7.66 x 1.78 or 8 x ? and nitrile or viton?
Recommendations?
