300TDi Alternator heat shield

Comrades, I've just had my second 100amp alternator fail, it would seem that the rectifier/diode pack is overheating, I've noticed on some exploded engine drawings that there was a heatshield fixed to the rear of the alternator to shield it from the turbo, does this come only with a Bosch unit (which I believe were the original units) or do they fit any Land Rover 100 amp Disco alternator and if so are they readily available.

Yeppers, I have one on order as of this morning along with a replacement diode pack and a new alternator, the old will do nicely as a spare, and yes, the Nippon Denso alternator seems to be designed to draw air through the windings from rear to the front pulley so cooling the diode pack first and the windings second, ( I confirmed this with the byproduct of a very fine H.Uppman Magnum 46 cuban cigar) so yes, the air would, if the heatshield were not fitted draw air off the turbo manifold whereas with the heatshild the air is drawn from the side/top.

Okay internet people, I purchased the Land Rover heat shield, and guess what ???? Yeppers it wont fit my Denso / Magnetti alternator :angry2: -- simply no way will the fixing holes line up to any of the bolts even with long extensions.

My guess is it will only suit a Bosch unit, (which I believe were original equipment) can anyone enlighten me on this please?
