C2 Fan Clutch

Re: C2 Fan Clutch

sorry,


Forget this post, I did catch Dave's comments above.

Can anyone comment on the one I pictured in post #12. Does it look correct for 66?

Did the part numbers change from late C1s to C2s?

Thanks,

Don

Re: C2 Fan Clutch

I found another one on Ebay that is listed as a 61 fan clutch. No apparent stamping on the face. Were the fan clutches the same for late C1s and C2s?
I know there is a difference in small block and big block, i.e. measurement from the mounting flange to the base of the bolts (boss) where the blade mounts.

How does this one look.

Don,

The 5-blade fan appears to be GM # 3789562, an 18" dia. fan with 4 rivets/blade and was used on 66-67 Corvettes w/AC & 64-67 Chevrolets w/AC.

The 5-blade 18" dia fan used on 58-63 Chevrolets has 5 domed rivets/blade, GM # 3749576.

The clutch appears to be the Eaton type used on 63-67 Chevrolets & Corvettes.
