I believe it's gonna be a difference in cup and ball size. I bet if you look real close the ball is not fitting in the cup correctly, not enough contact area causing overheating because only a small area of contact. imo


And the only lube I would use at first start up is black moly lub.

Best to buy those 2 things(adjuster and cups) from someone like Smith Brothers so you know what you have, size and hardening. There are different ball and cup sizes.



I dont think that is the problem. They balls seem to fit in the cups very nice. I did notice with the hughes rockers the adjusters (whatever they are) the ball is down in the cup more than with the HS adjusters. The HS adjusters leave a considerable more amount of ball of the cup... Both adjusters seem to fit the cup nicely.

If the HS rockers still show problems, I'll get a new set of pushrods and adjusters from the same company.

Trying to use what I have as the pushrods are Mantons and are/were new.
