power steering conversion question?

[dondb]

Thanks for all the reply's and help:}
I was able to get the belt to line up with some shimming...but now there is one more obstacle! My water pump pulley and crank pulley are so close together i can't get the PS belt on. Is the easiest route taking off the water pump pulley to get the belt on? I'm talking about 1/16 of and inch between the two.

I believe i found the problem? The WP pulley is the same size 7" across as my crank pulley. I believe the short water pump pulley should be 6.25" across? Is this correct??

My WP pulley was 7" and I replaced it with a 6.33" diameter, That allowed extra belt clearance. The flow might increase slightly but I have noted no difference. Additionally my main crank had a dual pulley but the rear grove did not align with anything, so i installed a bolt on third pulley that bolts to the face of the original crank

This is how close my wp pulley was to crank, pictures here

My 69 with Ac and Ps water pump pulley is under 6 inches and a triple pulley
it should work fine enough to give your belt space

OK...thanks, I'll order a new WP pulley smaller then the 7.1 inch one on there now. Now i'm wondering if the WP pulley was wrong...is the crank pulley correct? I measured across the crank pulley and it's 6.75 Inches...is that correct for a original 69 307 engine??
