Idler pulley
 

Randy:

I may need to replace an idler pulley. I have a blower, and it is the one immediately underneath the blower pulley. I have a 2003 4.6 motor. The surface is worn and has a cupped appearance.

Can you help?

maybe, is this pulley a factory Ford one or one that came in the blower kit?

I have replaced mine just about every year.

I just replaced mine, squeled and had some play in the bearing

Randy, it should be a stock one. I don't believe any pullies came with the blower except the blower pulley. This si the one right beneath where the blower one is located.

THe number 9 pulley?

Yup...that looks like the one. Thanks!

So, foncerelli what hapens to yours?

$13.70 + shipping and in stock

Cool Randy. I think I am going to replace the tensioner too. I have reason to believe it may have some issues. Can you give me a price on that?

Randy, can ther entire tensioner be replaced? Or, just the pully on it.

My idler pully started to squeak at about 60k miles since the bearings were going bad.

Ford only sells it as a whole asbly, $41.05 to you + shipping and in stock

Those P1SC's seems to wear them out. The entire drive system gets a beating. I have replaced power steering pumps, 2 altenators, 1 idler pulley, and 2 tensioners

Randy, how do I know if the tensioner is bad? How much of an effort is involved in replacing one?

easy to replace, chances are if the pulley is bad the tensioner is not far behind. how many miles? what is the condition of the belt?

The belt seems thin to me and is a bit beat-up on the outside edges. I don't have a new one to compare. BTW, with an otherwise stock 2003 motor and a Novi-2000, do you know what belt I am supposed to use? I can't read the numbers off the current belt.

I have a 2000 car with 67k on it. Last May, I swapped in a used 2003 motor that now has 12,000 miles on it (4,000 since theh swap). What I don't know is which pullies and tensioner was used. I guess I would assume that they came from the new motor, but I don't really know.

well the stock belt is a JK6-941 which is 6 rib and 94 1/8" and belts are normally good for 40 to 50k so it might be time for a new belt and tensioner

ok...stupid question: Do you use a stock belt with a Novi-2000?

no

i got this from MPH.

you could call up paxton and ask them.

Shit, I don't know what the dam size of the pulley is. I too have an I/C and run 10 lbs of boost.
