69 Big Block Pulleys- Help Please
I've done just about everything I can think of to eliminate belt squeal, including numerous scuffing & re-painting sessions but the pulleys themselves appear to be too worn & glazed to salvage. If anybody has any other suggestions to save them I'm all ears...well, all eyes I guess.
Short of that I'm looking for suggestions on a good source for quality stock replacements or, if prices are in the same ballpark, suggestions on quality aftermarket pulleys. If they didn't cost too much more I would like to free up a few ponies w/ a set of reduction pulleys. Any 1st hand experience/feedback on specific brands would be great. Thanks folks.

Hey Les,
Can you resize your sig Pic?
It's a bit big and means you have to move the thread left/right to read it all.
Check out you Cheby dealer. the pulleys should still be available from them and at a better price than the aftermarket/resto places.
I priced a BB water pump and PS pump pulley for my 68 from one of the suppliers at $200+, got them for $106 from the Cheby dealer. I think I got trade pricing but it is still cheaper.
You dont have any broken bolts on the mounting do you?
Allows the alternator to flex under stain thus loosening the belt.

I like you chased this down foe ever on my 69 BB. Did all the the things you mentioned and it would toss it's belt EVERY TIME at 5-5500 RPM's. Pulleys to the eye appeared perfectly aligned and were balanced. Going through the assembly manual for the umpteenth time found I was missing a tiny little spacer on the power steering bracket. Found a replacement and no problems since. You like I was are probably missing something small.

Andre,
Thanks, I'll take a close look at my assembly manual & see if that's the problem. I'm not throwing belts but that still may be the solution.
Silvr77,
Once I'm done trouble shooting I'll let oyu know if I'm interested- thanks.
RHD 68 L89,
All bolts are good. I used to have a solid parts discount connection at a Chevy dealership but he moved out of the area. I'll see what I can do though if I really need a new set. As for my sig pic, this is my 1st post since the new format here at the forum & I was shocked to see how my pic grew after the change. I'm not too computer literate but I'll try to figure out how to shrink it back down. I noticed that I'm not the only one who's had that happen.

If you have photoshop or ACDsee they have a resize function. Most photo manipulation software does.
Drop it down to half of the current size and see what that does.

It took my 15 yr. old son to do it but it's done! Now back to those damned pulleys....
It's always the young ones who are into high tech stuff, but can they tie shoelaces
