Thread: alternator

My D3 alternator died in Katherine last year. Luckily I carried a spare set of diodes and was able to replace them in the caravan park and be on my way the next day.

Alternator Rectifier FOR Denso Magneti Marelli Ford Volvo Mazda 237607 | eBay

PS. Make sure your able to remove the fan, big reverse thread nut, as that is the hardest part of the job.

That's the one, get the whole rectifier as per above link. As ytt said, the nut is sometimes undone with a rattle gun as it's so tight...Not sure that's the correct model though?

Hi ytt105,
Is the link to the right one for a D3 ?

Yeah I have Denso 104210 3710 which is a 150amp distributor but its not on that list.

Its from my ebay purchase list and it fitted my 2005 D3.

Do a search in Disco3.co.uk there's a lot of info there about replacing the diode pack.

Ok well what a drama!
Not over yet but I had the 'spare' alternator replaced with a new one, all good until the serpentine belt came off close to home a week latter.
Went back and the Auto Electrician was most apologetic.
Left the car with him and picked it back up.
Now 2 weeks latter I heard a funny noise and roughness in the engine bay, I got out and noticed something hanging down under the front of the car.


Hmmm open the bonnet and have a closer look:


Not good! Take out the engine cover, fan shroud and have a closer look at what may be the problem:


Upon close inspection and comparison to my spare I find the new one looks like it only has 5 ribs on the pulley where the spare has 7!


This is NOT ACCEPTABLE!!! Never going to last, let alone on the 5000 k trip I'm going on in 13 days!

But to make things worse I'm worried about the timing case cover as it seems to be damaged as well in 2 spots.


How should I deal with this? I'm going away for work until Wed (flying thank goodness)

Oh, I did get the new diode pack for my 'spare' and now it's fitted I have a good spare

Rich, I think the next step depends on your appetite for continuing to deal with someone who I would personally have no faith in anymore, especially with a long remote trip coming up soon.

Is it feasible to get a new correct alternator in time for the trip including fitting by someone else? If not, fitting the reco one is probably only course of action.

I know the person who has made the mistakes should be rectifying at their expense but for me, confidence in the outcome is more important.

Having said that you'd still have to find another guy to put it in and how to find a good guy?

It's a rock and a hard place scenario. Hope you get it sorted in time.

Cheers,
Scott

Cant you just swap the pulley from the old alternator to the new one.?
