I seem to be replacing the fan belt to my Alternator every year because it breaks. I have been told that my Four Winns service department is giving me the wrong one. How do find out if I have the correct belt or if I am installing it wrong. The belt seems to not just break but fray away leaving black pieces all inside the engine compartment. Any ideas on what is wrong?
 
have the alt tested it maybe freezing a second or 2.

The second reason might be the pulleys having rust on them.

Third reason might be they are not aligned the pulleys.

After my third belt i found mine was freezing second or 2 what i spent on belts i could have had the new alt.

DB electrical they are on ebay also

Hello...I am not a mechanic or well informed on these things...but have had the same problem on a used 5 litre Cobra I bought and have had the boat to 5 marinas over the past 5 or six years...None would focus on the belt when I said the belt kept fraying, snapping and filling the engine compartment with black rubber and leaving me stranded all over the lake. All the above "remidies" were tried...several alternators, Many many belts, new water pump to make sure they were spinning at the same rpm, new pullies, many attempts to "realign"...all wasted effort and money. My nephew who knows large engines simply identified the prescribed belt as being woefully inadequate in size. We worked through about 8 belts to find one the right size and strength and it has worked great all summer. It is an A39. I had to adjust the tension once very little once it settled onto the pully after about two hours. Buy a bigger and thicker belt~!

Make me laugh this changed that changed but they don't tell you after you offer a opinion on the op.

Then someone else jumps in and hi-jacks the thread. So who am i replying to ?

Guys have a problem why try to confuse us or should i say me. Post your own thread each problem is different.

Different boat, different water say salt vs fresh it all makes a difference believe me.

I, us want to help but i can only speak for me. I stopped replying to alot of threads even though i think i know the solution.

Ok got that said. To the second guy did they replace the crank pulley, could have rust on that one, or the pulley is gone. Or not lined up. Wrong pulley or alternator ?

See if you had the oem plulley, oem alt. and oem belt then it would all work good if lined up good.

So one or more things are wrong.
