Gaskets for my 51 ES2 timing chest

Posted by grant_macneill at March 21. 2017

Has there ever been a gasket for the ES2 timing chest cover ?

any idea where they can be had ?  Should I make one up or rely on the modern gasket-in-a-tube and hope for the best ?

Similarly, is there a gasket for the oil supply/return junction block to crank case joint ?

G'day Grant,

I do not believe these cases ever had gaskets. My 1964 model 50 works well with Three-Bond (1215) Yamaha (shock horror!) agents will have this. Fabulous stuff and may be removed with white spirit. However make sure you renew / check the oil pump fiber washer and inspect the oil jet /spring & pressure relief valve (if fitted). The oil pump washer  should leave a small gap between the cases and seal well once the case screws are progressively tightened. Works for me, Wellseal is good too if you can get it.


Good luck, Steve

I agree with Steve, I use Stag Wellseal on the Norton applying a thin layer on each face with a small brush and leaving it for 5mins, Its non hardening and comes off with petrol soaked rag. Three bond is good too!

I made a paper gasket for the oil feed/return block
