Hi mturri,
sorry to bother you, but this is driving me crazy!!! :censored:
I removed my alternator from a defender td5 ('2000), and I realised that the bearings have to be replaced.
I measured with the caliber the internal bearings (the one on the vacuum pump is in very good condition), and I measured:
Koyo 945 (grey; toward the vacuum pump) OD=40mm, ID=17mm, thk=12mm
Koyo 279 (brown; adjacent to the brushes) OD=35mm, I<d=15mm, thk=12mm
I checked on the koyo website but it appears that there is no part corresponding to the numbers on the bearings I removed from the alternator.
Moreover, on the koyo website I cannot find any bearings that fit mine!
I browsed the entire planet! I even tried the planets close to this f....g globe! :mad: but no luck.
I hope that you had more luck than I have and maybe you could give me any help where to find these bloody bearings!
Thanks a lot!
David

Plan B is call into a auto-electrician with the bearing, they have some in stock.
Hi Kylie,
thank, I have alreday called Koyo, and they told me to call Bearingwholesales, they have their bearings. I went today to the Sunshine store and got the right bearings.
Now the problem is the lid seal, it is bloody hard to find. Tomorrow I will stop by at the Toyota dealer in Elizabeth street near the Vic Market to ask for the part.
The other option is to buy it online from US, but it will take 20 days, and the price is 15$, but 54$ for the shipping!!!!:eek:
Let's see.
Done!
Now it is working fine....like new!

Very comprihensive and well done tutorial I'm sure many discovery owners will use this.
Hi,
Resurrecting this thread - I'm looking to improve the output voltage of my alternator (it sits at about 13.8 - 14v when warmed up). The alternator is original and I've given it a good clean an installed new brushes but the regulator is original.
Would this one do the job? 14.7V apparently.
IN249 Voltage Regulator for Nippondenso ( Denso ) type Alternators - 12 Volt, 14.7 Volt Set Point
PS: Reason is my drive to work is only 20 mins and the 2 batteries don't often get a big charge so would like a higher voltage from the alternator.
I found a source for the slip rings from a place called Baxters - the part number is NSR1.
$15 each - very easy to replace - just be careful removing the old epoxy from the solder joints.
Slip Ring Nippondenso 8.8 X 14.5mm
Hope this helps.

Would be good for charging the kamper batteries (which really need a 14.7v absorption charge).
My new alternator (Denso 14v) can start off at 14.6-14.8v baut after a while drops back to around 14.1v-14.2v and sometime later can drop to 13.8v-14.0v ....
... what's the likleyhood that this 14.7v setpoint would start off cold at over 15v !! ?? .... and progressively drop back to 14.7v ... could be a problem ... maybe a 14.4v setpoint would be better.
Did you pursue it any further ??
Hi Kev,
Not yet - got tied up selling an buying a house so will have to wait for a while as the new house is un-rennovated and the other half wants a new kitchen! - but I'll definitely pursue it before out next big lap in 18 Months, and probably do the job when I install a new engine harness Ive got stashed away too.
If you end up ordering one Kev, let me know and happy to go halves in shipping costs if you like.
Cheers
Simon
