Head Nut washer use Q....

[hardtimes]

Does anyone know of any negative effect/reason why hard washers should not be used under flathead cast iron head nuts ? Anyone use this method ?

[Pete]

No negative effects.
I use them because an alien friend told me to many years ago.

i dont know of any reason to not use them, they are needed on aluminum heads to stop the head nuts from galling to the head

Hey Pete,
Heck, that's good enough for me, as I've a bunch of ailing friends also !
I'm betting that you were told by the same alien friends that told big Al G the plans for inventing the computer,eh ? lol

I was just wondering if hard washers make torqueing more better mechanically ? That is, hard smooth surface to move on. I'm going to try some on my cast iron head project.

Yeah, I agree with using hard washes on aluminum and will be doing so also. Thanks

Yes.

On stuff like head nuts, main nuts and rod nuts, I use a dial indicator to read torque.

I lube the threads also.

Thanks, I'll graphite lube on the stud nuts then. Hm, what's a 'dial indicator' anyway.
For torque, I have four old timey torque wrenches and one brand new Snap On 300 lbs capacity, that I 'borrowed temporarily' from kousin Ron !

You put an indicator on the end of the stud and measure the stretch as you tighten it.

Hm, well when do you know ...when to stop 'stretching them' I'm guessing that I'm stretching them before I'm snapping them,eh? Or mabe they just snap ? Probably have to have some table/whatever regarding stretch and grade of metal/diameter ?
