diameter of the rocker arm ?

[bernardofeio]

Hello

I need to adjust the endplay of the rocker arm with shims. What is the diameter of the shaft so I can but them?

I already adjusted every thing and the ticking noise is still there. (it’s a ticking noise that increase with the RPMs and doesn’t change if the engine is hot our cold).

Yesterday I notice that one of the tappet rods had marks all around it in one section. Is this common?

Thanks

The shims are 15.5 x 26.0 and 0.20, 0.25 & 0.3 mm thick, or 5/8 x 1" in 8, 10 & 12 thou if you are still imperial.

Metric around here…

Is there any thing else that should be adjusted in the engine head?
