Flat spot:

You'd still have the roller 'axle' (acting like a hinge, for lack of a more eloquent description) which would still be better (less friction) than a regular rocker arm.

It doesn't 'roll' all the way round like the wheel it looks like, I don't think.

Ok Grav, I don't take issue with anything you said.

I still have questions about that mockup in the picture. I'm having a hard time understanding how that configuration of the adjusting screw and the locking nut can affect the valve lash/clearance. How can they adjust anything while at the fulcrum of the rocker? Is the WHOLE rocker being lifted or lowered? And wouldn't that simultaneously change the clearance on the pushrod side?

It looks ... I don't understand how it works. Here's a picture that has similar looking roller tip rockers but with the adjustment NOT at the fulcrum/pivot point, but closer to/over the pushrod end. THIS one I comprehend.

I read some more, I guess I did intuit it correctly, I just haven't worked on one myself. The whole rocker does lift, pushrod side and valve side. Huh.

Today I learned about Mike Mulligan, and his steam shovel, Mary Anne.

Adjusting shaft mounted rockers, roller or not.

BigV · 11-16-2018, 03:13 PM

That looks familiar...

Except for the light and the clearance and the unabraded knuckles.

Imagine cranking this over by hand, even with the compression release and geared crank, better hope the motor wants to start.
