Hi Guys

I've got a F100 with a 292 in it, the problem is the pulleys of the engine and water pump don't line up.
My water pump pulley is about a quarter inch too far forward.

When I got my '54 F100 it was already changed from the 239 to a 292 Y-block.
I think the engine comes out of a 59 or 60 F100 (casting number B9AE, crossover exhaust pipe).

I bought a new pump from cardone but this one was the wrong size, too small a shaft and impeller.

What would I need to get things correct? What pump, what pulley?

Pump thats on it now has a hub height of 4 3/4" and 3/4" shaft.
Pulley is over 7" in diameter and has a depth of 2 7/16".

The pump I think I need is a cardone 55-234 but I'm not sure?
This would have a 3/4" shaft, 4.7" hub height but I don't know the impeller size.

In that case I would need a pulley which is around 2 3/4" deep.

Anyone have more info on this?

 

How far will the alignment be off with the 55-234? I had to take a puller and move the hub on my water pump forward to get mine to line up correctly.

 

From the info I found online, it would be 4.7" hub height. This would put the pulley in the same position as it's now, 1/4" too far forward

 

You'd have to check the pulleys clearance but I'm pretty sure you could press the hub back that much too.

 

Whatever you end up doing be sure to write your solution down so when/if your water pump fails you won't have to try and remember what the solution is. If you're building it to sell the New Owner will greatly appreciate the info as well.

 

Truck will be for sale once I'm buried so I need a permanent fix.
Mounting flange seems to be tight on the shaft, don't want to use to much heat and destroy the seals.

I guess I'd better get some dimensions from cardone and go with the new pump first.

 

Correct No heat but mount is pressed on the shaft. Mine was easier because I was pulling it. You will need to press it. But trust me it moves.

 

Pump arrived last week, correct size for this engine.
Mounting flange was in the same place so I put it in the press and put a socket over it and pushed it as far as possible.
Still is about 1/16 too far forward but I'm at the end and I think the belt will take it. Might wear easier but it won't do too many miles.

Thanks for the help guys!

 

Glad you got the new pump and will be able to get it going.
