Alternator belts getting eaten fast! - -> Range Rover Classic

Alternator belts getting eaten fast! - -> Range Rover Classic



I know this sounds odd, but I recently replaced my alternator belt, make
the proper tension and about a week later, it started to squeal again, and
then it keep squealing and then, it got so hot it broke for the second time.



My guess is that the alternator is creating such a heavy load that it's
slipping and then burning the belt off.



Can my regulator be bad?



Any suggestions or feedback would be appreciated.



Thanks

check the belt tension is in fact right. If it's one of those with a very
short belt going from another pulley to the alternator, it's easy to have it
slack without it being obvious.

It ought really to be a 13mm or 1/2" belt, not a skinny one, if you have the
right pulleys.

make sure the belt alignment is OK.

first thing is to check alternator to see if its shaft still spins
freely , you may find its gone tight and thats why belt has gone ,
requiring a new alternator possibly ..

check the metal fan at rear of pulley to make sure it isnt touching
something and making it rub , although youll probably hear this if it
is .

also check that the aluminium casting in the lower mounting bolt area
is not cracked .

check battery has not lost its acid and youre trying to charge a dried
out battery .

in this weather its best to charge battery up with a charger every so
often and leave it on charge for a day .

belts dont like rusty pulleys, so check pulley and buff up with wire
wheel if needed .

hope this helps

Hello Austin.

Oh.. I think you found it, my belt is 9mm wide " a skinny one"

the pully spin's freely also, and the alignment is ok.

I'll get a 13MM belt from the dealer and let you know how it goes.

thanks for your help.

note that it has to have wide enough pulleys. some of the 13mm pulleys have
a deep V and will take either kind of belt. some have less V and if you put
a thin belt on 'em, they wear out before long:

pulleys belts
\ / \ / \ / \ /
\ / \ / \ / \ /
\ / \ / \__/ \_/
\ / \_/
\/

the pulley on the left will run OK with a thin belt (right) lower down the
pulley. The pulley on right will work fine for a very short time but then
the narrow belt will bottom out and it'll slip.

70A or more alternators rather punish a thin belt anyway, even with the
right pulleys. sometimes they run with 2 thin belts.

Austin, thanks for your help.

the 13MM wide belt did the job.

It was your suggestion that solved my problem.

Thanks for your help.
