Header Bolts

[DNK]

Anybody used these before

 

[tdskip]

Nope - but clearly you are Don

Bored are we? Or is there a specific thing that you are worried about?

 

[Brosky]

Interesting concept. Why the clip and do you take it off before the final torque down of the bolt?

And who makes these?

 

[startech47]

The clip holds on the "D" shaped plate that fits on the lower hexagon. The "D" prevents rotation of the fastener when it hits the header.

 

[Brosky]

OK, that I can see and understand. Do you torque the bolts with contact only being on those three tiny points of bolt head bottoms against the clips?

And who makes these?

 

[DNK]

After reading up on these,and yes it is winter Tom, I don't know if on a car that is not driven a lot they would be that special.
Everybody recommends several runnings and torquing before locking them in.
Will have to think about these a minute or so.
Paul, Google locking header bolts . You'll find several.

Spend yer sheckles on new lifters/pushrods!

Kids.


*sheesh*

 

[DNK]

Gee thanks for the advice Grand pa

 

[Scott_Hower]

They're pricey, but these are cool. You torque the bolt, then lock the set screw which expands the nose.

 

[Brosky]

OK, but do you remove the clip before torquing them down?

 

[DNK]

Yes The clip is only put on at the final and last torqueage

Put on or taken off??

 

[DNK]

Actually I was doing a little more research after you've ask SO MANY questions

Look here

Until final torque ,just the bolt. Then add the wing then the clip and your done.

OK How'd I do?

 

[DrEntropy]

Well.

I posit if ya buy a bunch of grade eight bolts, place 'em at the holes and POUND 'em in with a two-pound hammer, the threads will deform enuff to LOCK the fasteners in and ya got no worries!!! Kinda like the [censored]-house screws in high schools. One-way fasteners.

...until ya gotta remove 'em NEXT year.


What's so bad about a little LocTite onna threads of normal fasteners?

Or is this mill gonna see racing speeds and revs? That's a kettle of a diff'rent colour.

 

[Mickey Richaud]

So, is there such a thing as "Snake-oil Engineering"?

 

[DNK]

Just,Boys and their toys, Doc

 

[DrEntropy]

So ya gonna go fer new lifters an' rods then? :smirk:

 

[DNK]

the lifters and cam only have 1000 miles on em.
Prolly do the rods I want to measure em for correctness
