After installing a heatshield between the exhaust manifold and the dynamo/alternator location, I mounted my new Dynalite (alternator in dynamo housing). To put on the original fat (wide) belt, the alternator has to be pivoted towards the engine block. Even when the alternator touch the engine, I cannot put on the belt on the original pulley.
Does it means that the outside diameter of the Dynalite, 106 mm, is bigger than the outside diameter of the original Lucas C40 dynamo? My after market dynamo has only one outside diameter (102,2 mm), but I know that the original Lucas C40 is slightly different, for instance it doesn't have the same diameter over the total length.
A smaller pulley then the original one would solve this issue (and let also the alternator spin faster), but I cannot find it for the wide belt. May be I can try to take off the pulley and mount it on its axes with the belt in the groove.
I would be pleased with the dimension of the outside diameter of the original Lucas C40 and of course any other suggestion will be appreciated.
