Rocker Geometry on a pinto

[5tox]

on a pinto cylinder head you have the top on your valve above the spring on which sits a lash cap (i believe thats its name)

and on the other end of the lash cap is a height adjuster (dont know the correct name for this)

 

after fitting a new cam am i correct in saying that you would turn the cam so that particular valve is flat against its valve seat then raise the 'height adjuster' until the 'lash cap' touches the cam lobe then lock off the height adjuster with the lower nut

 

in theory keeping the lash cap nice and tight against the cam lobe at all times with no gap

go on kent cams web site to get the valve clearance settings failing that i will ring lee to get the settings for that cam then ring me i will tell you how to do it

No. Have cam lobe pointing up and adjust follower untill you get the correct clearance for your cam.

Pintos can be a bit tricky to set. Easy way to do is set up the clearance and lock off tight. Then using the size above and below the size you need check that the big one won't fit and smaller one falls in easy.

cheers buddy, ill have to get hold of the required valve clearances once i findout exactly what cam it is

my little brothers cam was a kent cams RL2 and the clearance settings were 0.35mm inlet / 0.40 exhaust

 

had a go tonight with a few spanners and a feeler gauge and bugger me its a fiddly job (not very easy to do on his kitchen floor in poor lighting) but we got there...

only problem i found was that after locking off the height adjuster it seemed to close the gap fractionally so the feeler gauge was a slightly tighter fit.

i think im being a little bit too particular though, im sure itll be fine

also each rocker seemed to be on the piss either left or right slightly so i had to wiggle it until it sat dead level to get a correct reading on the gap (if that makes sense) ... is this normal?

 

as said above, the correct sized gauge went in ok and the 0.05 size above was too big for the gap so cant be far wrong

Sounds ok to me. That's why I check them after with the bigger and smaller sizes. Rule of thumb it's better to be slightly bigger than tighter. My college lecturer drummed into us this "happy and loud,quiet and sad" better to hear that slight tap of the follower than hear nothing and risk loosing power or burning valves
