Ever since we got the BMC back in 1985 its alternator configuration has always been problematical and to be honest its made going on holiday a bit of a pain as it eats belts and doesn't charge properly after a few days as the belts have either stretched or have worn away.
The engine was obviously fitted originally with an dynamo. There are two pulley on the end of the crank - a big one which drives the water pump (and the alternator) and a smaller one which does nothing at all.
For the second time in 10 years the Alternator has thrown itself and taken the waterpump bracket out (which idiot decided to bolt an alternator to a bracket on a waterpump made from grotty alloy I do not know).
Some of the problem with the belts being eaten is that I'm sure the waterpump pulley is actually slightly eccentric/warped so it chafes the belt.
So are there any after market kits that we can get that will allow us to use a 60amp alternator, that preferably doesn't involve bolting anything to the water pump If it involves dropping the pulleys off the crank and putting new ones then so be it.
