1988 Accord

Alternator belt --- What is the other pulley for? The crankshaft pulley,
the alternator pulley, the ??? pulley.

I have a frozen alternator rotor shaft, the belt is no good. I was wanting
to cut the belt and take it to a shop. A full charged battery should make
it to the shop. Will the car run with no alternator belt? What is
mysterious pulley for?

TIA, Bill

 

Do you mean the pulley that's run off the same belt as the alternator?

That's the water pump.

Very, VERY bad idea to drive around with THAT not running.

 

Hi Tegger,

I had a good laugh at myself. Talk about being 60 years behind the times!

Thanks, Bill

 

you mean the extra set of grooves on the crank pulley? that's for the
air conditioning compressor drive.

see above.

 

in 86-89 Accords the belt that drives the alternator also drives the
water pump. (90s and later Accords the water pump is driven by the
timing belt)
i suppose you can drive a short distance without the alternator
working, though that will wreck your battery

But you would not want to drive the car without the water pump
working. Some repair shops offer towing for an additional charge. And
don't be surprised if the labor cost is too much. Replacing the
alternator on a 3rd gen Accord is a pain in the derriere!!

 

Oh, crap, not *that* again!

 

Oh yes, the dreaded timing belt again!!!

VW had the same design on their 90s models. But using the timing belt
to drive other things will only wear it out prematurely. Leave the
timing belt alone and it will last atleast 12 years / 150K miles.
Other than serving the purpose of forcing the owners to replace the
pumps on a 80K miles / 7 years interval, it's a stupid design!!

According to US DOT, the average life span of a motor vehicle is about
13 years or 145K miles final. So an average car would probably see
this kind of maintenance happens once in its life time. Statistically
speaking, that's not too bad. As i write this, my 89 Accord has 245K
miles on it and is running on the original engine and transmission,
second timing belt and third water pump.

But rich folks who drive lease vehicles don't give a f*ck about
whether it's a chain or a belt, and all this sh*t. It's the poor
working man who drives a 250K+ miles car that has to pay
attention.

So please do..

cheers

Timing belt life has zero to do with what it drives and everything to do
with its design. And the water pump imposes almost no load on the belt.

Two examples:
Toyota Tercel. Belt drives one camshaft and nothing else. Belt replacement
specified every 60,000 miles.
Acura Integra. Belt drives water pump and two cams. Belt replacement
specified every 105,000 miles.

The Acura's belt will actually last well beyond 105K, but by then you're
straying into dangerous territory. The engine is an interference design, so
belt breakage could be decidedly costly.

 

you have a set of teeth, no? well, they are but pieces of bone that
are held together by some sort of gum. A timing belt has a similar
construction.

oh really? it's just like saying the shape of your mouth has zero to
do with what you chew

you know what? try chewing rocks... haha
