I have an 3/4 race cam N/A 82 280zx. The car shreds the idler pulleys on both the a/c and p/s idler pulleys. I have both the brackets and the bolts to attach the pulleys too but ever since Jerry for ALL Z Car's in fort worth, Tx retired there are no z parts in the salvage yards.

I am getting off topic, does anyone know the specs of the v-belt idler pulleys? The inside bolt hole size, the pulley diameter? Reason being i want to just order several inexpensive ones from online since i see them all over the internet but you have to know the specs of what your trying to order. Anyone please help? Thanks to anyone that has info on the specs, thanks again!!!!!

you can go to a local bearing shop and get replacement bearings for bout 5 bux. its hard to find the pulley, thats why i went that route. they are super easy to change. sorry cant remember the part number

I think the bearing sizes are 20 X 47 X 14 and 15 X 35 X 11. Those are all in mm.

Thanks you guy's response. Upon my fiance's 93 celica timing belt snapping clean in half. I replaced it with Gates timing parts. And after looking online at their idler pulley catalog I began to think I have an option for no longer having a pulley just a bracket.

I am currently guesstimating Gates part # 38306 will work. It has the closet measurements for inside bore, v-belt groove area.

I will post measurements and pics if I can figure out how to upload.

Earlier in my post I should have said I have nothing for a replacement bearing to fit into. Wish me luck and if this works out we will have an option for if you just have the power steering adjusting bracket but no pulley and the same for the air conditioner.
