Alright guys, my 88' 300ZX is getting the idler pulley bearing replaced this weekend and I need to know what size the bearing is that is inside the pulley. Can anyone tell me what size it is so I don't have to take the car apart first? Thanks! -Purple_EnvyZ31

 

try the dealer or a car parts store

 

I picked it up yesterday. Now awaiting to put it in.

 

My idler pulley isn't turning at all and the belt is. My 88' Z31 broke down yesterday because of that and in my recent posts, I have an idler pulley bearing that needs to be replaced. In these cars, do you have the replace the whole thing or just the bearing?
