The assembly manual shows that I need a KF water pump pulley. Out of my loads of pulleys I can only find a KO and I have two differant sizes of KO pulleys. Does anyone have the measurements of a KF water pump 3 groove pulley?

This is for a 70 W-30 with A/C

I have a KO that is 5 1/4 inch diameter and a KO that is 5 5/8 inch diameter, both are 3 inch offset.

 

Here you are Eric.
Looks like it is 6" across.
The part # is 399404 KF.

 

Looks like the offset maybe
only 2 1/2 though. The waterpump
snout may have something to do with that?

 

Thank you very much! I am headed to my parents house to see what I have there. I have more engines there so I hope i have one there. Now my next question, Is this correct for a 5.60 inch water pump? I assume it is because i have the X water pump for my W-30 and the assembly manual calls for these pulleys.

 

Eric. KO is not correct for 70 w-30 to my knowledge. The X pump is a 5.6"

KO is a 72' pulley.

F-85 Josh should have what you need. Give him a call.

 

I found the correct pulleys at my parents house. Thanks for all the help guys.
