The belt that came with my alternator and waterpump pulleys is too long. I have a custom racing main pulley. The belt that came with the pulley kit is about 1.5 to 2 inches too long. I need a 5 rib belt that is about 29 inches long.

Any help would be greatly appreciated.

The belt that came with the kit is 31.5 inches long.

 

Good luck. I ended up using a 4-rib which worked just fine.

 

I have a 4 rib that I will use if I cant find a 5 rib.

 

I ended up using a 4-rib belt aswell. You'll have to take the belt down to your nearest Autozone, Kragen, Napa etc... and measure it up with the smallest 5-rib they carry. If they don't have it, a 4-rib will work just fine.

 

Just go around to auto parts stores and ask. Most belts are numbered uniformly:

295K5

3 digits together = belt length (add decimal)

single digit = # of ribs

So in the above example, the belt is 29.5" and is 5 rib.

Anything from a 29 to a 30 inch and 4 or 5 rib will work, so it shouldnt be hard to find one. Dont have them look up a part for a specific car, explain to them that this is a custom project and you need those specs.

 

I got a 6 rib Goodyear Gatorback belt and just cut off one rib carefully with a pair of scissors... it has been on my FD for about 3 years now with no problems.

 

sr motorsports has these. Thats where i got mine. Mine is a 28.5 inch 5 rib belt and fits my greddy pullies with a indigo, i think, main drive pulley. give them a call.
I think their web site is just srmotorsports.com

Your best bet is to go to a local Autozone or NAPA and say you need a 5-ribbed Serpentine belt 29 or 29.5-inches long.

For a Goodyear Gatorback, the pn# would most likely be 4050290 or 4050295, or for metric:

5PK710 (29-inches long) or 5PK722 (29.5-inches)

However, I don't think it is made.

A 4-ribbed one does exist at Autozone:

Goodyear Gatorback pn# 4040290

Very good info Kevin.

 

Kevin you know to much...

 

NAPA 25--050290

29" 5 rib if you want it, I have one free...just pay me for shipping


for RotaryRessurection that convention is NOT UNIVERSAL as evidenced by the above part number

 

How someone can be such a nice guy in one breath and such an *** in another is beyond me...

Note in my post I said "most belts" not all are numbered universally. I have never had a problem tracking down appropriate V or serpentine belts by decipering the part numbers. But of course not every aftermarket company follows this same pattern, yet you can usually study the numbers for a minute and figure out that they've just been transposed. The 290 and the 5 are still present in the PN posted above, yet as pointed out the number is not exactly what I posted that it might look like.



Since this seems to be somewhat uncommon information (as evidenced by the few posts on the subject) I figured I'd help out by posting what I know. But now that I've officially been e-bitch slapped, I guess I'll stand back and let you take it from here.

this is exactlywhat I thought about you...

"Most belts are numbered uniformly:" is misleading.



and your comment is not consistent

p 7 lists a 29.0 X 5 rib for $10 and change circa 2000.

RotaryRessurection, I apologize for the less than positive comments.

 

Goodyear's Gatorbacks follow two conventions, one for English/inches measurements, and the other for metric lengths.

4= Serpentine Belt
04/05/06= number of ribs
xxx=length in inches
y=length in tenth of inches

4050290 = Serpentine Belt; 5-ribs; 29-inches long EXACTLY

for metric it would read:

X= number of ribs
PK= Poly-Serpentine Belt
xxxx= length in millimeters
5PK0710 = 5 ribs; Poly-serpentine; 710mm long

Seems like a lot of people lately are sackriding goodyear belts. I like a dayco personally. With a serpentine belt slippage is usually a minimal issue regardless, so it's not much of an issue on an FD. Belt selection is often more important on an FC with V belts that tend to slip and stretch easily.

 

A few years have passed since the last post. Has anyone found a good place to buy these 5 ribbed by 29.5 inch belts?

 

I usually walk into advance and tell them I need a certain size belt that cant be looked up by application. We walk to their belt area and find the closest thing they have, usually in dayco which are the best belts.

 

Napa belts are made by Gates. You can go to the Gates corp web site and find the length and part #. Then go to Napa and get the belt. I know this because the air pumps for auto and manual trans cars have different pulley sizes. The automatic is the larger one of the two.
