1963 fan clutch part number

[Kevin H.]

I am trying to find the correct fan clutch part# for my 63 FI. The parts book I have shows 3814560, but I cannot find where that is or has been a valid part#. The clutch on it now is stamped CK, and I cannot find any other numbers. I believe this is the incorrect clutch . Any help would be appreciated. Thanks

63/4 describes the configuration of the fan clutch. Also states what stamp is typical. Can't remeber but I think it should be CK or CJ

GM #3814560 is one of the fan clutches originally installed on 1963 Corvettes and is the most likely one originally installed on your car. Also, it was a valid SERVICE part number---at least, it was until May, 1973. At that time it was discontinued and replaced by GM #3916141 which remains available to this very day. It's not configured just like the original, but it's similar. In any event, it's the closest you can get in a NEW fan clutch.
