239 crank pulley
Howdy,
I'm looking for a front crank pulley for my 239 V-8
It's in my 55 F-600. The water pump is driven by the inner most pulley and the fan is mounted to the water pump casting but it's on it's own bearing/sheave up above the water pump pulley.
My existing pulley has a chunk broken out of the outer (wide) sheave and the fan sheave is a narrow sheave. So I guess I either need a crank pulley for a truck that has 2 sheaves on it...both narrow.....Or a truck pulley like the one I have here PLUS a fan sheave that's a wide one.
I know there was several combinations that worked.....I just need to get one of them that will work on my truck.
I bought a crank pulley from Joblot but they sent me a crank pulley for a flathead!
They list the correct crank pulley in their catalog but they don't actually have it in stock.
Anybody out there with one of these?
If I can't find one I may have to try to machine one out of Aluminum or something!
Thanks!
Rick

Since the chunk is broken out of the wide sheeve, and the driven water pump pulley is narrow, will a narrow belt work, and maybe be "under" the breakout point? Just a thought. Like I mentioned a while back, I have been using a narrow groove alt pulley, narrow groove crank pulley and wide groove H2O pump pulley, with narrow belt, and have not noticed any slipping at the pump.
Also, I have a forum budy in a 1942-47 truck group that works at NAPA. If you give me the part number they have maybe I can get him to research it and come up with something.

Hi Mike (did you get something from me in the mail btw?)
The part number is an EBV 6312-A Joblot did list it in the catalog. They just didn't have one in stock.
The wide sheave does not line up with the fan pulley. Also the broken area goes all the way into the bottom of the sheave. I would actually like to use it. I could weld it probably, but it still won't line up with the fan pulley. I am convinced that I have the wrong fan pully for this application. It should be a wide pulley on the fan but it's a narrow one.
The sheave for the fan pulley needs to move about 0.5 - 1 inch forward.
I think I can weld or braze a new piece on the crank pulley and put it on a friends lathe and clean it up but it still will be offset with the fan pulley. I can also make a fan pulley on his lathe too and give it the correct offset.
That might be the best bet if I cnnot find one.
It would be easier to just find the correct pulley of course!
Cheers,
Rick

Hi Roger,
I have been watching ebay recently but I quit when Joblot told me that they had one...turns out it was the wrong one....So I have to start looking again!
I will also have to find a wide fan pulley. What a hassle!
I have that distributor all ready to go, I have the newer oil pump installed, the pan back on and this is becoming a road block!
It's always something huh?
Regards,
Rick

You may be better off getting a double groove crank pulley that has 2 narrow grooves. They were used in the cars and can be 1 or 2 piece cast iron. I have one on my 292 with a 3rd sheave bolted on for A/C and PS. You could also change to the later style water pump that has the pulley on the pump instead of the high mount type. A custom aluminum 2 groove pulley is available now. Sounds like you already have that pulley. Check out pics in my gallery. You would also need a different fan shroud for this setup from a '56 F100 with V8 or go to an electric fan as I plan to do. All the parts on the front of my 292 were found on ebay. The 239 that came in my '55 F100 had the high mount fan with the wide belt. I had a hard time replacing that water pump in 1997.

This is exactly what I'd like to find.
I was told that if I wanted to change to the other water pump on my 239 that I'd have to change the timing set & timing cover. I really don't want to go there just yet. I just want to get it running. My crank pulley is the cast iron with 2 pulleys the inner one is the narrow and the outer one is wide. THey're about 1.5 inches from center to center.
You're right...if I were to change to the water pump-mounted fan I'd have to change the shroud etc...
I still just want to get it running...I think the easiest will be to find the correct pulleys and bolt it all together......of course if I cannot find them then I guess I'll have to do a "plan B"!
You had a 239? HAD? no more parts left huh?
I considered using an electric but they're pretty expensive and if you work a truck pretty hard I'm told they cannot move enough air. They're fine for cruising around empty....
If I can find a double groove pulley I'll grab it for sure. If you see one please let me know!

Sorry, I sold the 239 to a guy in Oklahoma that was restoring a '55 f100. I had two 292 engines to make one good one and got rid of all the excess parts. 292 parts are easier to come by than the 239 since it was only produced for about a year and a half in the trucks.
Give Bob's F100 Parts a call at 909-681-1956. They have a lot of used parts.

Thanks anyway Roger,
I don't think I have to have a 239 pulley, I think I can use one from any of the y blocks since the front crankshaft diameter is the same. I only need one that has the grooves in the right place.
If I have to I'll weld up this little broken area and clean it up on the neighbors lathe.
I'll keep looking though....thanks again for the info!

Yes,
This is what mine looks like. The only difference is that the fan pulley I have is a narrow (fan) belt pulley with the wide crank pulley(outer groove)!
Pretty wierd huh? I can probably fix the broken piece in my crank pulley. I can easily weld a piece of cast iron in that area and clean it up on a lathe....but then I'll need a WIDE fan pulley and probably the correct bracket too!
Any ideas?
I did find a pic of the wide belt with the high mount fan. The wide belt just runs the fan and the narrow belt runs the generator. This was how my 239 looked.

I've never seen a car pulley.....is it as long? That one of mine sticks out there pertty far. It appears to be about 7" from the shaft end to the end of the front pulley.
It should probably be about 1" shorter though since the outer wide groove doesn't line up with the narrow fan groove above.

Since you have the wrong fan pulley for the wide groove crank pulley, the 2 groove car crank pulley should line up with your fan pulley pretty close. Later truck Y blocks used a one belt setup with the fan on the waterpump shaft so you may find a single groove truck crank pulley, but it still will not line up with that high mount fan pulley. I found another good pic of the wide belt setup. It has been modified from the 6 volt gen to a 12v Alternator. Can you show a pic of the front of your engine with the fan pulley?
The most common setup on the trucks with Yblocks was the single belt with the fan pulley on the waterpump like the pic below. It was used from 1956 to 1964 and should be the easiest to convert to if you can't find the original style for '55. I am not sure but I don't think you have to change the timing cover to switch out the waterpump. You might try finding a junk motor on the cheap for the parts.
