Workhorse serpentine belt for 8.1 engine

[hawg6]

After searching the IRV2 site for the a correct aftermarket serpentine belt part number or the physical size, it appears that some people have installed 103 inch long belts and others 108 inch. Assume the belts would not change from one RV manufacturer to another, but could from one WCC production year to another. Anyone know the correct belt is for a 2004?

This link for the Serpentine Belt should answer your question.

I now have more numbers to work with. After looking at it, and reading the posts, I think I know less now than I did before. It seems there is no clear "one size fits all" to this question. In the AM I'm headed down to my coach to retrieve the P/N from the belt itself (if I can Still read it).

I ran into the same thing on my previous Ford v10. Seems the belt for my 05' was unique to MH's, .... go figure.

The answers on the link are conflicting.

I had my belt replaced on 10/26/06 at 22494 miles (now at 28376). They put on a Gates Micro V K061080 belt. I kept the Gates cardboard wrapping & purchased a spare one (same). I also assume it's a 108 inch, & seems to work ok (note that my WH is a 2003).

To keep my sanity, tomorrow I'm calling WH to confirm the P/N & length.

I have a 2004 Southwind with the Workhorse chassis, I took the original belt to the auto parts and compared it to what they had, the 108" belt was the same as mine.

On my 2001 the belt is one hundred and three inches.

hawg6:

Guess the best way is to look at the numbers on your existing belt.

A Chev truck dealer said that the two different sizes could be accounted for by two alternators, in lieu of the usual factory installed, one.

Thought I had the 108" per our owner's manual. Turns out I have a 103" belt. I keep one of each in our spare parts box. (Just in case you need one)

[Thudman]

Can the Tensioner be adjusted to use either the 103 or 108 inch belts?

Maybe this Gates cross reference site will help:

Read the number off your current belt that's on the MH. Mine is W0000581 and it's the original belt. Enter that number and click. You'll get two belt numbers (note the 108 within the belt number). Click on the Gates number ending with a "HD" - you'll get the length in inches and millimeters. If you want a crude conversion trick for millimeters write 12 on a piece of paper. Draw a slanted line through the 12 like this 1/2. 12 millimeters is approx. a half inch. I know it's crude but it helped me. After 15 years, I'm up to 25 millimeters is a crude 1" - purdy good eh??

[Thudman]

I lost you on the 25mm = 1". Purdy bad eh?

Re Gates: What's the difference between the K061080 and K061080HD? If the HD is "Heavy Duty", why?

I don't know what the HD stands for but it had a more detailed explanation than the one without the HD.

As far as the 25mm - hey! it took me 15 years of major league concentration coupled with many hours of repetitious "flash cards" torture and an occasional flogging by the metric police. I know its 25.4mm but that translates to 1" and a fuzzy.

Off topic # 2. Thudman, seems to me you're into aviation. Check out this beauty. http://howard500.com/

Is there a "map" that shows how the belt is routed over and under all the pulley's, etc. ??
