Probably both of these belts may be the original as well as the heater/radiator hoses - may be time to change them all.
Ken, so there are TWO serpentine belts, right? Any idea what the numbers might be? Are they the SAME? I want to order online but when I went to Amazon, it didn't seem to help. Unless I'm inputting in wrong information. I put: "1996 Ford 460 7.5 engine serpentine belts" but I'm not getting too much information. Any suggestions? Maybe I should go to a Ford dealer. But will they be able to help since my MH is 21 years old?
btw, I'm sure both are/were original belts. And if the belt I broke also runs the water pump, how come I didn't overheat? And yes, I"m gonna replace both.
Thank you!
EL

Glad you have it working. Suggestion: if you change the remaining belt(s), you might want to keep them in the coach storage as emergency spare(s).
Charles, I doubt that popping was caused by the belt. It had a distinct sound. I think I can distinguish a sound made by a broken belt. This was not that kind of sound. btw, any idea what the numbers are on those two belts?
Thanks for your input

Go to NAPA Auto and input your VIN# to look up parts.

Once you get a #, maybe Amazon can cross it over for you.

Here is a picture of my 460 engine showing the routing of the v-belts Click image for larger version

Name:	100_3938.jpg
Views:	34
Size:	330.1 KB
ID:	190462 My v-belt number for alternator is Gates K060505, v-belt for power steering, water pump is Motorcraft JK6602. The upper radiator hose is Motorcraft KM-4941, lower radiator hose is Motorcraft KM-4969, and the lower by-pass hose is Gates 21909. As you can see both v-belts go around the water pump pulley/crankshaft pulley. In all likelihood all of your belts and hoses are original and I would change them all. I bought all of my belts and hoses from RockAuto in July 2014 but as twinboat mentioned, NAPA would probably be a good source as well. Good luck.

Hi THenne, it DOES have an emergency start switch. However, I am brand-new to this model and I had not read the manual thoroughly. Now that I've found it, I can see where it may have helped me. "you can get the engine running by using the emergency start switch. The 12volt battery that powers the 12-volt circuit in the living quarters is mounted behind the front bumper with your main automotive battery that is located by the engine. The emergency start switch on the dash works like a built-in jumper cable that temporarily connects this auxiliary battery to the main automotive battery. Push the button on to make the battery connection and, then, turn the ignition key. Release the button when the engine starts. You may also have an optional second auxiliary battery." (that I don't know.)

I went to my friend's body shop and his parts man ordered the two belts. One is K060505 which works the alternator and the air pump. I didn't get the JK6602, instead, I got the Gates K060675 for the fan, the a/c, and the PS. I did not get any hoses, but thanks for the reminder. I'll get them tomorrow. My mechanic will install all this coming weekend when we will be getting mid 70s temperatures. Perfect weather to work on the MH.

Not sure if you found this or not however here is the Gates webpage for your F53 chassis

Also, the procedure I pointed you to in post 17 (1st link) for checking the charging system would have found the bad/missing belt in step 5.

Here is Service Manual information for 1997 F53 chassis manual (listed under F super duty in that era). I use the 1996 - 1999 digital manual ($9.95) myself for ref info,

Most receipts will disappear in 90-days if exposed to light; photocopies are best, but many AP stores now maintain computer warranty records too.

Hope you have answers and resolution/ solutions by now, but visual inspections can often answer many questions, even if unknowledgable about engines.... most can see the shiny pulleys of a missing belt, or shredded remnants of broken belt, or physical damage where belt was thrown off... My wife was often very good at pointing and saying "WHY does that look funny or so/ so?" (or finding the bolt I dropped in the grass.)

TIP: The Emergency Start Switch can also use the Chassis/ Engine battery to BOOST the Coach battery so you can start your coach generator, should your coach battery run down too far

I thought that as soon as I read about the popping sound.
Don't feel too bad I had a similar problem, alternator not charging, battery good. Even went and bought a refurb alternator, went to remove the old one and thought, hold on what is that loose wire doing, hmm looks like it matches that ring connector with only a stub of wire left on it...........

My rig is a 99 daybreak with the Chevy motor. Same kind if thing happened to me right after I bought it. Ling story short turned out it was the battery. Pulled a house battery that had different posts in it. Disconnected the chassis battery. Used jumper cables and was able to drive it home safely. So many different things can cause the same effect.
