Does anyone have the serpentine belt number for a 2006 cummins with a jake brake and also have AC on it? Need to know the number need for a back up. I know it will be longer than the stock one. Can't find the number at any auto parts house. Hate to have it break and not be able to find one when far away from home...Thanks in advance

 

Sent a PM.

 

I could use the # also.

 

Question:

If you order a new jake brake kit for a dodge diesel truck, does the kit come with a new longer than std belt?

If so, you could call the company that sells jake brake kit and order a belt from them.

If the longer belts are that hard to find, sounds like for sure, you need to keep an extra belt in the old tool box.

 

Found the serpentine belt number it is, 3947077 a Cummins number. I crossed it with Goodyear Gator Back which is cheaper and probably just as good. I have used Gator Backs before with my other truck no problem. The Goodyear number is 4081295 which fits Ford 3500 turbo diesel cargo vans. I found the Gator Back on Ebay for $23.79 free shipping. I could not find a local parts house that had any numbers for a Cummins belt with a jake. After some research and a few calls those are the numbers I came up with. Hope they work as I ordered a belt from Ebay. The cost of a Cummins belt was alot more any where from 80-100 bucks depending who you ordered from..

 

Great price! Genos stocks them @ $64.95+ shipping. # 3947077. You scored!

 

The belt new is 129.5 inches. Following are a list of numbers.
Cummins# 3947077
Mopar# 53041270AA
Banks# 65120
Gatorback# 4081295
NAPA# 25081298
Dayco# 5081300
If you can't come up with a number, like a previous poster said "ask for a belt that fits Ford E-350-450 Econoline Van with 6.0 diesel with single alternator".

 

The belt is an 8 rib, 130" length.

 

Thanks so much. Very helpful
