V Belt Spacing on 3 Groove Pulleys

Post by hEaT » Thu Jun 07, 2018 10:17 am

Currently running a 3 groove crank and alternator relocated to the AC position and no PS. This setup only lets me run a single belt on the middle groove as it'll hit my bracket and more importantly, the timing pointer.

Had the smart idea to get a 3 groove water pump pulley, space the alternator further outboard, and run belts on the two outer grooves (i.e., the second main belt groove and the former AC belt groove). Sadly...the spacing between the first two belts is not the same as the spacing between the second and third so that means the belts won't line up with the grooves on the alternator pulley.

Total long shot...but are there alternator pulleys out there (Ford 3G) that I can find that would have the odd belt spacing of using the 2nd and 3rd groove on the crank and water pump? I'm currently using the stock 2G alt pulley spaced a bit off the case.

Thanks

Or maybe no one knows the answer.

Perhaps you can find a Pinto alt. bracket which will allow you to put it back on the driver's side. Just about everything else from the factory has power steering. I have used a three-groove belt system with a crank-driven A/C compressor and a three-groove water pump pulley (PO had installed), but other than the one longer belt, to cover all three, it was all factory. Accessory drives are one place I like to stick with factory parts. I like the serpentine belt setups, but they all use PS, too.

It's a lot of specifics creating a scenario unlikely to have been seen before - I'm kinda not surprised nobody has the answer.

Wasn't so much my post specifically, but overall nothing new really :(

The Pinto idea sounds like a cool one to explore John. I need to figure out which year since I've seen passenger side brackets too (puts it where my alt is now). The comment you made about the crank driven AC is exactly what I was trying to do (grabbed a factory 3 groove water pump pulley to match my 3 groove crank), but the OEM alternator pulley didn't play nicely with how the grooves are spaced with regard to the 3 groove pulleys.

My setup is what Mike sells, before Mike sold it. I think where I have my turnbuckle mounted is what causes part of the issue. No power steering is what gives me the timing pointer issue.

OIC.

That's because all the problems have been solved?

Does this help at all? looks like it sources parts from "Pinto Engined Granada or Transit parts:"

Thanks Chris, it does.

I wonder with that setup, with power steering gone, does the belt clear the bracket...That's where I see clearance issues on my current setup and I'm not keen on spacing the crank and water pump pulleys out to clear.

I found this which also looks promising. I could run the outer belt it looks...

If you're looking to convert, Im using that 2 belt WP serpentine pulley and I'm about to swap it out for a single and I have that ranger bracket and alternator, collecting dust.
