Thread: '96 Disco Tdi300 ALTERNATOR - which one?

I am pretty sure you can service the one you have, Much cheaper that getting another alternator

Pulleys are swappable, no big deal. It's even possible to swap the old 300TDi mounting plate onto a low mileage V8 alternator, should you happen to trip across one.

should be able to source both. i thought the smaller pulley was the later version. mine was the smaller one and bought if fairly recently (few years) magneti marelli alternator. think thats the OEM one. can always swap pulleys as mentioned. from web search i just did, can source both types.

how do you know it's playing up? not charging battery? or just your tacho jumping?

Nah, on 1st start up u can hear the noise of it. I've removed the main belt and started the engine and it was quiet so it pointed to either the Water Pump; P/S Pump or ALT. When I manually turned them all turned freely except for the ALT Pulley, so from that I'm assuming the bearings are on their way out. Volts & Tacho all good.... for the moment

Is the Alt pully getting hot when running for a bit ?

Pulley size wont make any difference to the Alternator. But it will make a difference to your belt length just enough to be a PITA to tension on a bad day.

Basically any alternator that will fit will do the job, Get one off a Hyundai if you have to,

Apart from basic wear and sometimes the module ( or good old fashioned diodes if they ever go ) they will go forever

I did wonder if there were other brand vehicles that the Alternators might be able to be used.... Do u have any more info as to which models/year?

Just find one that will fit. Wont matter what it came off

Your local wrecker will have heaps of different makes and models. Just find one you can make fit
