All,

I am finally getting around to converting my '74 F1.5 accessories to a 2F setup to add power steering.

I got the accessories from a '79 parts truck a while back and the truck is long gone.

On RockAuto it looks like there is a split on that year - 1/79 and older is different than the later part of the year.

Does anyone know what the differences on the water pump would be? Anything I should be concerned about? How can I tell which fan/clutch I have?

Thanks!
CAZ

Water pump configurations are all over the board. There are at least 3 for my 78 and I've returned 1 and ordered another due to that problem. If you buy locally you'll be able to swap until you get the right one.

This is a good thread on water pumps :

https://forum.ih8mud.com/40-55-series-tech/534283-water-pump-answers-sticky-faq.html

Btw : Do yourself a gigantic favor and buy OEM. I replaced mine this fall with a Rockauto unit and an internal bearing went south in less than a month. I got my money back and got an OEM unit from here for $88.77, including shipping.

Post up some pictures of your current set up. What harmonic balancer do you have? What water pump pulley do you have? What PS pump bracket are you going with?

I guess I should ask a more basic question first....

I have a '74 with a direct drive fan. Can I use the '79 alternator and brackets without changing the water pump?

I have not chosen a power steering pump bracket yet - just trying to gather the parts and get my engine ready.

Where are you going to mount the alt bracket? Does your head have the taped holes?

ETA: These pics helped me a lot...

I have the "fan clutch" pulley shown in the picture that I pulled from the '79. My engine currently has the one labeled '73.

My block is tapped for the alternator bracket.

Maybe you have a 2F block.

Do you have a two-jaw puller? Pull the flange that goes to the pulley off the new waterpump, slide your old flange on...
You can put either fan on any waterpump.

Sorry all, I don't think I read enough before I started asking questions.

It looks like I can just slap on the alternator bracket from the '79 with a new alternator and leave my water pump alone since I already have the double pulleys.

You need to post some pictures of what you have if you want answers.
