Pulley ID help

[4spdragtop]

Ok, I have a surplus of pulleys and would like to know what they are for. I will keep adding more to this thread as I get them sandblasted and cleaned up. I have dimensions/pics and part #'s if they have them.

Thanks all!

1. part #3698805 dbl groove water pump pulley 5 7/8" dia and 2 1/8" high(1st 2 pics)
2. Part # 3769148 crank pulley, dbl groove. 7 1/4" diameter, 3 3/4" high(pics 3 &4)
3. No part#, crank pulley double groove, 6 3/4" diameter, 2 3/4" high(pics 5 &6)
4. No part#, water pump pulley, single groove 6 1/2" diameter, 2 5/8" high (pics 7&8)

Thanks for the help!

The last one (water pump) pulley looks like a late 60's vintage for either a SB or BB.


I'm not sure about the crank pulleys. I could guess, but then I would be pulley'ing your leg.... LOL!!!

#1 is an A/C BB or SB top pulley, not sure id have to go measure one
#2 . that one should come apart, i believe those are 2 seperate pulleys. the short one being a SB/BB non-P/S crank pulley , and the deep one for when A/C was added to #3. IIRC, that deep pulley will sit inside #3
#3 that is a non air BB and SB crank pulley which may or may not have offset holes for different balancers, but can be used on all, which i have done
#4 BB water pump pulley no-air

Thanks everyone for the help, 73abodee, #2 is 2 pulleys together, but it sure looks factory. So with ac, the ac belt runs round the crank pulley, the wp pulley, ac comp pulley and the alternator?? It runs round 4 pulleys?? That belt would be as big as the one I would get across my arse in public school!!

Now my questions are, which sb and which bb?? I dont need extras and I want to keep what I need for my 69 340 non ac non ps cuda. As well as keeping any sb ac ones related to dads 67 273 ac/ps cuda.

Another cry for more help I guess. LOL



Thanks again guys

I did some internet research and from what I can tell the dbl pulley 3698805 is from an 80's 318 with ac.
