Interesting thread, thanks! But no dims for the FZ crank. Same for another thread titled '1FZ crank pulley dimensions.' And so it goes...@landtank may have some input
Here's a previous thread discussing pulley sizes:
Small alternator pulley
The battery always seemed low on my 1993 since I don't drive it very far. So I made a new smaller alternator pulley to keep the alternator rpm's up and thus the possibility of putting out more amps at lower engine rpm's. In making the pulley this small, I felt there was not enough metal left to...forum.ih8mud.com
Yeah. Aftermarket alt maker looking for a diameter to work up a power curve, but I don't have a tool that'll measure it...
Outer and the grooves where the belts run, which is the actual working diameter. Calipers or careful measurement with string or wire, if someone happens to have a de-belted pulley handy…Got a sketch of what they need to know?
Is it just the outer diameter?

Thanks! Confirms @mudgudgeon's work above. Interesting that it says three pulley and only specs the two we need. Still don't have the PD measurement pointed out by @mudgudgeon: diameter of belt on pulley. Can anyone measure that--or an actual belt from 'top' to 'bottom?' Anyone have a new belt set sitting around...? @NLXTACY, perhaps? We could get an approximation of the the pulley's inner diameter if we had an accurate measurement of an alternator belt, and the space between the belt top and the pulley's outer edge (assuming the belt bottoms out at the pulley's deepest point).Forgot about this, Rockauto sells a crank pulley that is identical to the original

IF the belt bottoms out in use, then measuring the belt depth in free space on an installed engine will give us the number to subtract…
Mmmmyeah. Apparently it's not as simple as I thought. I keep seeing illustrations like these. Lemme ask the guy if he even needs this spec; maybe this is a rabbit hole we don't need to go down...The belts sit flush with the outer edge of the groove, they definitely should not bottom out in the groove.
There's a polished wear mark that shows the belt contacts the first 5/16 of the groove. (Darker line in the pic above).
I'm unsure if the pitch diameter is measure at the outer edge of the belt as it sits in the groove? Or centreline of belt etc
I would think at the outer edge of the belt, as it's the circumference of the belt.
That would make the pitch diameter same as OD in this case.
maybe this is a rabbit hole we don't need to go down...

Has hg if it's this part #
This is a great thread btw. Lots of useful info
What does it do to displacement if you bore out .5?
Gotta wonder how that translates to torque and ponies. .934% gain!It would take engine displacement from ~ 4.476L to ~ 4.518L
