how to determine if I have chromoly pushrods?

[ARTIFACT]

(newbie alert)

I know it's been asked before, and I searched. The answers worked for previous posters, but I think I need more explanation here ... How do I check this?


Franklin installed the engine in my 57 a few years ago, but doesn't know (without driving it there - but read on).

I got the car recently. I am doing the valves for the first time on my own, and followed the .006 instructions... I have *not* started the engine, because I read about these chromoly pushrods, and I am unsure. I know, I should have checked *before*


How do I check this?

Are there photos I can use to compare and identify what I have?


Thanks guys

Use a magnet... it will not stick to aluminum pushrods.

And usuall y but not 100% sure the chromoly ones are normally a black color!

Nope.

Use a magnet.

Only the tube is made from aluminum, the ends are steel on both.

Why the hell do they call it a gland nut. its obviously a big fat bolt!!!

[ARTIFACT]

Ok

magnet sticks to pushrod body

... So now I need to understand what 0.000" is supposed to feel like ... Hunting for the feeling gauge... Thinnest I have is 0.002...

Do I get it adjusted to "tight .002"?

I am sure all of this is obvious to all but me learning a lot each day I spend with my beloved bug

thx

if the pushrod will rotate but you cannot feel any lash it is adjusted to "loose zero" clearance, which is what you want.

I use the method that a lot of guys on here use for getting "zero lash" and that is to adjust the rocker adjuster (screw) in until it doesn't have lash, then slowly back it out while using your fingers to spin the pushrod. When you can spin the pushrod easy with your fingers but there is no lash present, that is considered to be zero.

...with chromoly push rods...is the "loose zero" adjustment on both intake and exhaust valve? Local shop owner had mentioned he was running .002" on intake and .004" on exhaust...but not sure what material push rods he was talking about.

Thanks.

[youngnstudly]

Yes, I run zero lash on all the valves.
