Alternators

What is the correct 'size' for a 1984,  1800cc DX engined cabriolet (if that makes any difference?). Mine in making a distinct whining sound from it since the belt was tightened up. The garage said that the bearing are worn.. is that right?

Cheers, Dan

Hi,alternator is probably a 55 amp my GX and diesel have 45 amp bosch units,my citigolf has a 65 amp fitted,
The bearings do go,if you buy a new one try and get a bosch remanufactured unit or something of similar quality.

Thanks Bert, Its only been in just under 4 years so I hope the next one does better. (Is 4 years poor? I don't really know).

Hi dano,my 83 GX has the origional bosch alternator and starter motor,my 83 diesel also has the origional alternator and starter,i only buy bosch or lucas units when i replace them,delco remy units are good quality too,when i say remanufactured i mean almost every part replaced exept the casing which makes no odds,reconditioned in birmingham means a clean up and a coat of spray paint  8O
which means my customers get the benefit of loosing there cars twice!
Thats why i am always booked up.
cheers Bert

German French and Swedish I found did the best deal for an exchange unit.
   It cost me a total of around ?60.00.    Lucas electrical garages can replace the internals, like diodes etc if they are gone, which is sometimes cheaper. There is one in Yeovil Somerset that I used. But if the bearings are going aswell like mine were change the whole unit.  4 years is poor, my last one had done 21 years and 140k . I must get a medal from the club or something.

ps    Having the belt to tight is a sure way of wrecking those bearings !

Blimey 4 years is awful!

 Especially as it is a genuine unit! My advice is be careful on how tight you go with the belt, as it can put mega-pressure on the bearings!
