1930 Exhaust valve lifter

Forums

Hi,
Could anyone please help with detail of the exhaust valve lifter parts for a 1930 500cc overhead valve Norton?
My model 20 is missing the complete assembly which I think consists of three parts.

5741 exhaust valve lifter lever
5742 exhaust valve lifter bolt/nut
5743 exhaust valve lifter spring

if anyone can help with either parts for sale or even just parts I could photograph, measure or copy I’d be really grateful.

Many thanks Ian

Ian. I had the same problem with my 31 Model 20. The previous owner removed it I think during the 40's

I had a machine shop make up a new one using the diagram below.

I then bought a exhaust lifter that was too long and had them cut & Weld to the correct length.

As for a spring I just happened to have  one NOT the coil type  just an ordinary spring

Hope this helps

Hi Ian,

What a fantastic old drawing. It gives all the details I need to get the parts made. Thanks ever so much for taking the trouble to share the information, really grateful.

Cheers Ian
