Need BBC pulley pictures - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Als454 · 04-16-2004, 11:54 PM

Can someone get me pictures of the pulley setup on a BBC with A/C and P/S. My truck did not have A/C originally, I added it. I need some clarification on how the belts and pulleys are configured. Thanks

flip66, I have a few questions. Pictures are kinda are to make out.

How many grooves do you have on the crank shaft pulley? I thought there should be three.

Belts, should there be...?
One for the alternator, Going around the alternator, crank shaft and water pump.
One for the a/c going around the compressor, water pump and crank shaft.
One for p/s going around the p/s pump and crank shaft.

3 grooves on the crank. the 1 closest to the block is for the alternator, #2 is for the air conditioner, #3 is for the Power steering. 2 grooves on the water pump are for the alternator and the air conditioner. I will see if I have an old picture of my '72 setup.

Not really sure. Is it original or did it come out of a recycle yard off a c40-60 where they used 2 belts.

Is kind of hard to see you are right about the way the belts go I do not have the ac belt on so the grove you see is were it is suppose to go,. I can get better pic if you need them

One for the alternator, Going around the alternator, crank shaft and water pump.

One for the a/c going around the compressor, water pump and crank shaft.

One for p/s going around the p/s pump and crank shaft.
