Diagnose broken rocker

[priobe]

Ok here is an update.

Not sure why others have eye brow imprints on the bottom of the rocker but here is what I found.

When installing the rocker the adjustment screw is pulled all the way back off the push rod. When installing the rocker assembly this will push the pushrods into the bottom of the rocker.

Every rocker has 3 to 2 turns of thread. When flipping the rockers over there is no way the pushrod cup can come into contact with the bottom of the rocker.

Now, according to Dove, the rockers should have 30 -40 thou clearance. After measuring it doe not seem it had this clearance on the side clearance. This may have been a factor to the breaking of the rocker arm.

I have some wear marks on the shafts for the rockers, Dove mentioned that this can possibly be polished up with Crocus cloth. If not I would need to purchase new shafts.

I will need to inspect the rockers to see if there is wear also.


Now, if I change the complete set. What rockers can I use with out altering my heads?

And are the Doves' that bad to not reinvest money to correct the findings.

My pushrods measure up at 8.926. After speaking with George at Gessord he said they are pretty short at that measurment.

Spoke to Smith brothers and they walked me though the measurement process and 8.926 is the correct length.
