One says Dayco 00086, the other 00039. Google searches can't find them. Is there a prefix or suffix that I need to add? I'm sure Whipple will tell me, but not tonight.

 

Can you describe the pulley? Grooves, size etc.

 

What pulley you looking for mike?

 

Thanks, guys. I was trying to Rock Auto them last night. I called Whipple and they gave me the new Dayco numbers. My local store will have them tomorrow, probably sooner than ordering them online.
The two grooved idlers are Dayco 89004 and the smooth one is 89003.
It was funny, I pulled into a store Sunday and I heard something dragging. It came off when I turned into a parking space. I got to look what it was and laid out behind me was the blower belt, an idler pulley, and the ball bearing cage. It looked like a parts diagram.
The other two pulleys sound like their bearings are dry, so I am replacing them all after just replacing the tensioner last year.

 

Glad you got it figured out.


As long as you didn't loose the Doi.... Oh never mind. Lol

 

On a side note, Pat, it does behave better in the idle department without that pesky blower turning. Particularly not fully warmed and coming to a stop. Since no air is going through the blower at idle, it must be the drag it creates. I bet increasing accessory torque in the tune will help.
I need more spare time to tune more.
