Alternator not so good!

[Sally+3.9 Suzi]

Hey all,

I have had a squeeky alternator for the last year or so now hoping it would just fade away!

However now it's rooted and the pulley is slopping around the place making a bit of noise!

I'm guessing it's just the bearing inside? Has anyone had to change one of these or replace one of these?

It's the stock nippo jobbie.

Any advice would be great:)

Cheers Nick

It would have been cheaper to fix it while it was only making a noise - it may now be beyond economical repair! You could be lucky and it is just the bearing, easily replaced, but if it has stopped working, there is likely to be consequent damage, such as a burnt out field or windings.

Can't hurt to pull it apart and look at it, but if many parts are needed a replacement is likely to be the best answer, possibly a higher output one.

mine cost approx $250 to completely rebuild, for that coin is it really worth the effort of taking it apart yourself?

I got a new Chinese pattern one for about $220 landed. 75A.

When you remove it be careful not to split the oil return hose which is on the side of the alternator that you can't see. Like I did.

Mine made similar complaints when I got the car and it kinda burnt out one of the two belts that drive the compressor fan and alternator- in the end it turned out to be the tensioner bearing- on mine (with a/c) its a dual pulley single unit type.
It cost me a few bucks to replace the bearing but its an easy job. Don't overtighten the fastener bolt though....
Later on I had the alternator reconditioned as it's output was swaying all over the place- the gauge will tell you this. Check the external regulator if you have one. The alternator cost about $370 to fix. This included R/R. I didn't have the time to take it apart and do it myself. It was just the bearings but other items were serviced as well for the money.

Thanks for the response guy's!

I ended up melting a fan belt 200 metres short of a auto electrician who bent me over for $600 installing SHi*#y generic job + vacuum. After putting a clutch in her a week before I was over it and paid the price!

I hate mechanics....

Out of interest would the size or capacity of the vacuum on the rear of the alternator which runs the brake booster have any effect on the brakes?

Any way it's running a hole lot better.

Thanks and happy tinkering:D

Unlikely - the level of vacuum would be pretty much the same for any of them, and the only effect of differing volumes of air pumped would be to change the recovery time between brake applications - almost certainly the recovery time is so short with any one made that you could not tell the difference.
