Flywheel pulley spacers?

[Satori]

Do they make a spacer for the flywheel pulley on a SBC? I have the new pulleys installed, and the flywheel pulley is about 1/16th inch closer to the motor than the water pump and alternator pulleys. You can't see the difference in this pic, but it's a pic none the less. :lol:

that would be a crank pulley your speaking of, and yes they do make spacers for that.. jegs or summit racing probably..

 

[Brucer]

nice looking engine also :lol:

How embarrassing! Of course I meant crank pulley.

Thanks, I'll look for one. What would you say would be the minimum thread length for the harmonic balancer bolt? After bolting on the pulley there's about 3/4 inch grabbing. It'll be a little less with a spacer.

Very little less not to worry, that's plenty.. what do they say? 1&1/2 times the diameter of the bolt? 1/2" bolt? Should be fine...

That's a good rule of thumb to know about. I'll get a closer measurement when I get the spacer.

That just hit me.! If that is the rule, why then are NUTS not that thick?? hehe

Lol, good point!

Well I guess it is because there is suppose to be thread hanging out past the nut... not the case in a blind hole.. as for sure someone will jump me for saying that.. hehe

What pulley setup is that you have, if you dont mind me asking. That looks sharp, Im in the pulley market right now.

I got them from Summit Racing.

Crank pulley: p/n MCH-6381
Water pump pulley: p/n MCH-6322
Alternator bracket: p/n MCH-20120
Alternator: p/n PWM-67295-114

Is the crank pulley flat on the damper, I know it my sound simple but some pulleys have a cup that seats in the damper to center it and it is about a 1/8" so it is worth a look.

Mine has the cup that seats into the damper, so any spacer I find will have to be similar.

All this talk about nuts and pulleys made me wonder what site I was a for a moment... good thing no one brought up belts!

Al, you like dem kinky sites?? hehehe
