2f alternator on 1f adapter? (1 Viewer)

[pc4400]

Hey everybody,

Well Ive been using a 2f alternator on my 1f engine. The alternator works great but my adapter (a bike part I hammered into shape) finally broke. So which should I do?

A. Get an old 1f alternator and swap the guts from my 1 year old 2f alternator. Not sure if the guts will swap into an older 1f alt.

or

B. Get/find/make a better adapter for my current alternator to work on my 1f

Here's a pic of my rigged adapter before it broke

So has anyone else made/used an adapter to use a 2f alt on their 1f engine?

Looks as if a modified adjuster would be the easiest way out........

The correct alternator pulley would be nice, then the stock wide belt could be used.........

Yep, the alternator case fronts are different between the 1F and 2F, so a modified adjuster would do the trick.

You could also find a junk 1F alternator and swap just the case fronts. That is the only difference in the cases. Follow this link and look at the very last pic on the page. It shows the differences in the cases.
