3.0 Under Drive Pulley

So I just bought an under drive pulley for my 3.0. My question is do i need a different belt for this or can I use my stock belt?

When you buy the set from I can't remember the website the set comes with a new gator belt. But I don't see why you couldn't use the stock belt. But since you have it off, check for cracks and replace if needed!!!!

 

I didn't buy the set, I only bought the crank pulley

 

No, the underdrive pulley is smaller and you need a smaller belt, im not sure what size, i know a guy on the other site that knows what belt you may need

 

the guy with the 2wd yellow truck 01rangerdanger maybe I know he installed the underdrive pulley

 

put the pulley on, take a piece of string and loop it around all the pulleys in the proper order. then measure how long the string is.

 

Is there anywhere online that I can buy the belt that was supposed to come with this pulley? I tried their website but it says they don't sell these pulleys anymore

 

is it the underdog under drive pulley?

 

Yeah its underdog

 

I think those use the same belt .
here is an old linkI had saved a while back

So I can use the stock belt?

 

I would think so

 

Ok sounds good. I'm gonna give it a shot tomorrow

 

I was wrong , it does require a different belt

 

For single belt 3.0L Ford "Vulcan" engines;
-With air con, Dayco part# 5060870 or a Goodyear & Rubber co. # 406087 (87 inch)

Gatorback belt # 4060872 for the 3.0 with a/c.

Some trucks like a slightly shorter belt and an 86 inch will work as well.

-Without A/C, Try a Dayco (or equivalent) belt # 5060850 (85 inch)

The belt should be easy to find because it's a common size.

best to measure or contact underdog

 

Thanks! What worries me is that when I put the new motor in I used the pulley assembly from a 94 which is bigger than a 99 assembly, so would that matter at all?

 

take your old belt off and measure it , the only two other belts I know of are listed above, ones a couple inches longer

 

Yeah that's what I'm gonna have to do

 

Do you happen to have the link of where you got it? I really want the under drive pulley.

 

I got it used from a member on another forum
