Jubilee valve adjustor

Jim Lynn · Aug 16, 2010

I"m restoring a Jubilee. The valve adjustment is different than other engines I’ve seen. Normally the type of adjustment is a slot for a screwdriver and a locking nut around those threads. What I have is hex head adjustment, but they don’t have a locking nut on the treads. I plan to find nuts that fit the adjustment and add them to lock the adjusters. The thing that bothers me is the adjusters seem very tight.
Can anyone shed any light on this for me?
Thanks,
Jim

those adjusters are very tight for a reason.do not take them off and put nuts on them.they dont need it. just turn right or left to get the right clearance

You don't need any nuts. I had a Rambler that had the same type adjustment. Hal

they're interference threads...locknuts may make them unusable.

Thanks to you all. I will do as you all seem to suggest and that is use them as is.
