Looking for specs on OEM or AFTERMARKET pulleys

[upgradedsupra]

I am looking to get the angle of the grooves for stock pulleys or the unorthodox design. You will notice that they are flat slots (if you will) but have a v as it goes up to the top. Does anyone have any info on this as I have searched all over the net.

Thanks in advance

Duane,

what part of the pulley are you asking. Where the belt sits or the risers that keep the belt in place between each of the 3 pulleys?

Duane

better yet check you email

All the accessory belts use K section, poly-V's.

If that is what you're after, I scanned a page of the sizing on it (couldn't find anything online either).

I am looking for risers..I guess if you call them that. They have a slight angle to them at the top. (V)
Since I posted here I might as well say what I am doing. I am making my own custom design pulleys. Alt, water pump and PS. (although that is gone now)
I am planning on having a counter bore where as the stock and aftermarket has none. (Looks cleaner) Also I want to make them a lil different style. Will see how it works. I have the material to start but just need to get exact dims first. The rest on the lathe is pretty straight foward

Yes I have pulleys now but they are not what I want. I think they could use a better touch.

Duane

PS: Got the email :biglaugh: I assume it is the same as the rest of the pulleys? ZSince it is just the one section I need.

Duane: Easy way around this if you're not planning on production would be grab a piece of HSS and grind it to suit the existing pully then plunge cut them.

All you need are the groove centres 0 first cut then move the topslide xx and plunge the next groove and so on.

Plunge cutting or making a form tool would be a good idea but making it CNC would be more accurate and then I could make them down the road if I wanted. (not sure yet)

I assume you know a lil about CNC also I am working on a few parts for my Supra this winter. Been busy!

Ahhh got ya Duane!

Didn't know if you had access to CNC equipment!

In that case I'd run the digitising probe over the stock pully and generate the code based on that so it's 100% accurate.

Hmm, works okay here and I'm on a different computer from where I posted that file. This PC has no software for me to resize or manipulate the thing. Sorry.

Let's try again. Previous file was zipped with Winrar, this one with Winzip. The picture is too large to post directly.

as you saw from th CAD drawing the diameter is taken from the highest point on the pulley grove itself (the 5.295 for A/C, and the 5.498 for Water/Alt, and Power Steering). The same thing applies to the pulleys themselves.

Thanks for the info. I will see what I can do with it and get things rolling!

Also I want to thank you also Shawn. Everything helps I can see the pic now.

I will have one of my parts back tomorrow from clear anodizing! Maybe I will post a pic of it. Just a lil something for my magnetic pick-up.
