underdrive alternator pulley - 1/2jz

[ed]

heya

just wondering what folks have used for an underdrive alt pulley on the jz engines?

anything swap off another vehicle?
anything like a waterpump/fan pulley come close?

sources for aftermarket pulleys? not interested in annodised bling

cheers

There are lots of options for JZ engines, unfortunately most of them are anodised bling but that doesn't mean it won't work. I've seen a lot of them on eBay.

A bit of Googling turned up this:

It's a whole kit but only $110, not too bad?

yeah, but i think that shite is just an underdrive crank pulley, and std dia on eveything else. i want to specifically underdrive the alt with its own larger pulley

[Norbie]

Yeah OK, I'm sure I've seen stuff like that before, just can't remember where.

It wouldn't be hard to get one made if you know a good machinist? Or you could use it as an excuse to buy your own lathe.

It is, i have the set bar the water pump and crank pulley here. All standard with a smaller crank.

The pulley is approx 60mm (my verniers cant 100% measure the contact points at the valleys, but it varies between 60mm and 65mm valley to peak), 6tooth belt.

Hey there mate...

was going thru the book today and looks like the v6 1mz camry motor is the same just alittle bigger... just need to remove it and check the shaft size it sits on..

the 1jz dia is 61mm and the 1mz dia is 71mm, not sure if u want bigger....


let me know as i will pull one off a scrap alt and just thro some money for postage

Ed my 1JZ had an alternator from a 1UZ on it (importers must have swapped it over cause the motor had a front end smash), after getting the proper 1JZ alternator for it I realised the pulley from the 1UZ is actually larger diameter (but same offset/rib configuration). Have you got any UZ alternators laying around to check?

Hey there.. sorry the 1uz is 61mm not the 1jz

the 1uz ive got here is 60mm on the outher ring, and looks about 59mm on the inner lips for the belt

the one that ive got is 57mm to peak of grooves, 53 or 54mm to the depth of the groove

depth from the face of the pulley to the face of the mounting flange is 22mm
