Hi Paul,

There seems to be two types of mounting for alternators,
boss mount and case mount from what I read.
I can not figure out the difference neither what is
more applicable for the 13B.

Also 60 Amps seems to be on the low side for Canada is it?
heater fan, pitot heat etc....

Any idea?

Thanks

JP


I don't know the definition of a "boss" mount or "case" mount.
Do you have pictures. Most just use the stock Mazda alternator
mount and some move it over to the side of the engine.

Is that a boss mount?

Paul...here's what I found defining the two...and, BTW..there is a third
now...B&C make an alternator that mounts in the vacuum pump hole in the
accessory case of Lycoming engines...of course, that won't work with the
13b, but I just thought I'd mention it.

The arrow in the picture is pointing to the alternator boss mount...a
case mount doesn't have this boss, and requires mounting to three of the
case half bolts.

OK Thanks Harley.
