302 belts and pulleys?

The factory single groove water pump pulley on a Maverick chould be 6 61/64 inch diameter and be stamped with a C9OE-E part number. The SMALLEST V8 pulley made was 5 7/8 inch and that was for a car with A/C and no P/S ....

Of course ... the smaller the pulley the better cooling ... so it's really the depth that matters most ...

 

I guess I should have pointed out that the single groove pulleys that I have are NOT off a Maverick. Well, at least the ones not on the Maverick...

I have some, but they have small crank pulleys.
IIRC, they came out of large cars with small engines. (302 or 351w)

Therefore, if you seek original stuff, I would listen to Dan.

I would trade a crank pulley for a water pump pulley but it has to be the part # that Dan said. Let me know.

 

So far, I see a C9OE-8A528-F, about 1 3/4" deep, and C9OE-5809-F that's about 2 3/4" deep (one groove W/P pulleys) Any numbers for the right crank pulley also?
Thanks for all the patience and help so far.

 

I`ll check tommorow but the crank I think was a D00E- 6312-A # I will look at my car and get the #`s off my pulleys for ya. The 1 3/4 deep one sounds like the wtr pump is it close to 7 inch`s across. The crank is close to 6 5/8 inch`s across. The water pump is C90E- 8A528-F. I have a extra crank pulley but need a water pump pulley. Hope this helped

 

I looked at my single pulley sets that are laying in the shop today...
I was surprised to notice that the water pump pulley is larger diameter than the crank pulley.
I went to grab a tape and measure them for sure, but some employees got me side tracked and now I am at the office on the computer... 2 miles from the shop.
Sorry. I will get numbers and measurements today sometime.

I looked at the ones on the Mav, and they look to be about 6"+/- and both appear to be the same diameter.
The ones for the multiple belt crank pulley are definately smaller diameter and recessed much more. I don't have a multi pulley for the crank to see relation to wp pulley size.

For another twist, my uncle (who I reference a lot because he has about a dozen old Fords and enough parts laying in the yard to build a dozen more) made his own setup from mix match parts.
He has a double belt WP pulley off a car with P/S no A/C. Apparently the crank was single pulley and the second belt for another accessory was run off the water pump soley. Anyway, he took that upper pulley, combined with a 3 belt A/C-P/S lower, and runs 2 belts on his WP, Alt, and crank. He says he wants to keep it cooling and charging even if one breaks... He considers it more durable. I don't know that I agree, but he did it.
The 3 row crank pulley had 2 rows the same diameter than lined up with the WP pulley. So he took the 3rd, larger diameter row on the front of the pulley and cut it off with a cutting wheel. Then ground the surface nice and smooth to the 2 rows he was going to keep. The result is a very clean, stock looking 2 row for the crank. He used a 2 row for the alt as well, apparently they are not uncommon.
Anyway, just thought I would clue you in to the possibility of modding stuff to make what ya got work.

All those that I have, Maverick or not, are:
6 7/8" dia for the WP
6 5/8" dia for the crank
They looked smaller in my memories

I wrote the numbers down, then left them on the desk...

 

On my maverick i ran a supintine belt with know idler i did this for looks over function. If you go to scrap yards there are a million and one water pump pulley for ford 302's so I found. What I had to do is biuld a spacer for the water pump pulley so everything would line up. It seems to be working very will.

 

My 84 F150 has the double pulleys for the alternator, one went to the A.I.R. pump [smog], waterpump and crank, the other just waterpump and crank. P/S was waterpump and crank, A/C was just crank, idler A/C. Yep 4 belts. Only run P/S and one Altenator belt now, smog gone and a/c no longer works. A lot of semi truck engines run 2-3 belts on the alternator and fan, that way if you lose one, hopefully the rest will keep you cooling and charging [unless your luck is like mine, one breaks and takes out the rest of them ].

 

Put part#s in my other post

 

Sorry for no update, been camping from Fri-Sun afternoon, then R/C plane pylon racing from then till dark. Finally Wed was able to go to the track and look in my storage building, and there was one crank pulley I had not seen earlier! I guess all the others may not have been SB, but this one fits/works, and I'm using a double W/P pulley. Thanks for all the help, I knew what I was looking for after the measurements got posted, I now know the diameter was too big on most of these. Thanks for the info again!
