Feel a bit silly but I can’t seem to locate part numbers for the pulleys on either side of the SC on my v33er. Only pulley the local carquest can find is the tensioner for the power steering. Is this a dealer only part after all?

dont waste money buying a new pulley,the only new thing you need is the 5 dollar bearing thats pressed in the back of the pulley which can be bought anywhere, very easy 10min job to replace bearing.

I would replace just the bearing but the pulleys have a bit of wear on them. Might still be the best option though.

I am pretty well educated on rockauto but the options they list doesn’t need have what I think I need. Unless there is incorrect pulleys on my truck.

Rockauto has a few options. a bunch of v belts, obviously those are not right. The one that looks the part is for Power steering. Just like the car quest people saw but I need the ones on both sides of the SC. Hence my question. Maybe it is the same pulley after all but I was hoping to get confirmation.

When you see the cost you will probably recondition the ones you have. Don't damage the bearings pressing them out until you get the number off of them.

The oem has flanges on one of them, but otherwise they appear to be the same size. The aftermarket has dropped the flanges for some reason. I suspect nissan put those flanges on there to prevent the belt from dropping off that pulley. But it seems to be close enough to the crank pulley to keep it in line.

Whatever you do, don't go too cheap on the replacement. Poor quality chinese bearings will fail in short order.

I went with the genuine Nissan part when it came to replacing mine just for that reason. For the other pulleys, I went with Gates.
