[1968 GTO Resto-Mod]

working height of flowkooler waterpump #1622 is 3-5/8" according to their website.
they also mention 1/16" gasket thickness.
i've got a couple crank pulley plates already and also ordered 2 more from frank's.
i think they are about 1/32" thick each.
anyway, i'm prepared to do a bit of spacing at the crank... i'll know more about the water pump when it shows up.
thanks for your help!

What's the part number stamped on the Ford pulley?

[1968 GTO Resto-Mod]

ford crank pulley part number 1816348C1
see attached photograph.
thanks for your interest!

If that waterpump flange is 1/2" closer to the motor than mine, you shouldnt have to space the crank pulley too much. Im thinking .100" maximum.

[1968 GTO Resto-Mod]

got the power steering pump back from lee manufacturing a couple days ago.
i was curious about how it would line up with the crank pulley so i mounted it up and put the straight edge on it.
would the power steering pulley described in post #72 (80's era chevy truck) still be a good bet?
i'll try to get back to the salvage yard as soon as i have a chance.
thanks for your input guys!

unfortunately, No The early pumps like yours with the bolted key is not interchangeable the late press fit serpentine pulley. Being a press fit there is some adjustment fore and aft helping the alignment of the belt.

[1968 GTO Resto-Mod]

right, right! that's right jimmo's setup used the press-fit... thanks!
hmmm... where to start looking???
anyone know which rigs in the salvage yard might have serpentine p/s pulley with keyway?
thanks for your help!

Some toyotas use a key way. I have no idea what bore size they are though. If your heart is set on using that pump I am sure we can collectively figure out how to use it.
The price for this one from jegs really isnt too bad but judging just from the photo it appears you would have to move the power steering pump forward quite a bit for it to line up. http://www.ebay.com/itm/March-Perfor...2d8dde&vxp=mtr
Another option would be a pulley like this http://www.dormanproducts.com/gsearc...word&q=300-009 mated to a custom made hub with a 5/8 keyed bore. This would probably be more expensive than the march pulley but the hub can be made to space the pulley EXACTLY where you need it to line up.
With all that said, I wouldnt worry about the PS just yet. Your next mission should be to find the water pump pulley to line up as closely as possible to your crank pulley. Serpentine water pump pulleys that drive in a clockwise rotation are VERY LIMITED. Most manufacturers drive them counterclockwise and they ride on the smooth backside of the belt. They have no grooves and are useless for this application. If I remember correctly I only found 3 candidates in the scrapyard..The crown vic, the taurus(plastic composite) and the bronco(offset was way different).
Once you do some light shimming to line up your crank and waterpump, your other accessories will need to line up with them. The crank and waterpump pretty much dictate where the belt will ride because they arent nearly as adjustable as all the other accessories can be with spacers and brackets.
sorry the post was so long, hope this helps.

jimmo,
the power steering pump pulley you've linked to in post #318 is described by the seller as being a 5-groove pulley.

i placed an order for the water pump pulley fasterfiero linked to in post #319 and as far as i can tell from the pictures attached to post #321 this pulley has 6 grooves.

the cs144 pulley that i ordered for the alternator also has 6 grooves.

my assumption is that a 5 groove power steering pulley would be incompatible with the others which have 6 grooves, but i wanted to run it by you just to be thorough.
what do you think?
thanks for your help!

I picked up a bunch of pulleys off ebay,

ford 302 crank
standard ford/gm alt

Doorman 300-008 power steering, it will need a keway cut but should fit the early
pump.

also this water pump pulley

[jimmo]

Fasterfiero, do you have that waterpump pulley in your hands yet? if so would you mind posting some measurements? I wonder what application that waterpump pulley is for originally. I searched "Harry's u pull-it" hi n lo for a gm with a ribbed pulley and came up with nothing. Anyone in this area knows "Harry's" is a HUGE yard. If that one works it would save a lot of trouble.

[fasterfiero]

roughly

6" diameter

2" overall depth

1 3/4" mounting flange to edge of pulley

mounting flange is .25 thick dual bolt pattern and the bore ( .625 )seems tight on the first
water pump I tried it on, the shaft on the pump is pretty crusty....

[jimmo]

Cool, thanks for the info. What car are you modifying?

400 engine, I saw this thread a long time ago and have been collecting parts for the build.
I have not had a chance to mock up the pulleys. I think that it will be do-able without too much work. The trick seems to be the crank pulley and the water pump pulley need to be close the rest can be moved easily.

[1968 GTO Resto-Mod]

flowkooler waterpump #1622 showed up yesterday.
i bolted it up with gaskets in place and the mounting surface of flange sits 3/8" ahead of crank pulley front edge.
alright- so i'll try to focus on lining out the water pump pulley next... thanks jimmo.
it's so cool that so many people are thinking about this mod.
you guys are awesome.

Now measure from the front of the water pump flange back to the crank shaft pulley.

[1968 GTO Resto-Mod]

this is a different angle of the same photo posted previously.
after measuring i had to put the caliper down to take the photo with my right hand.
i put this offset from front edge of crank pulley to front of water pump flange at 3/8"
am i missing something here?
all thoughts are appreciated,
danny

[jimmo]

I might be jumpin the gun here but I think its looking really good. The crown vic WP pulley should fall right in place or at least close enough to be shimmed into place. That f350 crank pulley solved the issue of your waterpump being 1/2" short. That was one lucky find.
Looks real good so far.

[Ollie]

Measure from the front of the WP pulley mount flange to the back of the crank pulley.
That will tell you how deep the WP pulley needs to be, measured inside.
