Are they asizable new ?

Only if there is NOS laying around. HPH maybe?

Elliot's broke into pieces. He welded it and then welded a doubler on to it. He thinks it will last awhile.

The brackets are barely up to doing the job. they take the stress of a shaking heavy alternator. Thick load bearing washers could help. Was looking a a better bracket. the U shaped one is more simple to make thicker. The curved one is a more complex shaped stamping. Maybe a two piece weld together curved bracket of thicker steel ?

just used available maybe mark will step up and make some new ones

First look at where they break,
Then figure out why they break (bad alternator imbalance, over tightened belts, age/fatigue?)

The bracket is the "fuse" in this setup.
If you make a superior bracket will the vibration then transfer into the shroud? Possibly breaking the stud or cracking the shroud?

The type 4 bus engine uses a much longer version of our bracket and it doesn't fail, why not?

Has anyone looked into a more current technology (aka smaller, lighter) alternator?

You mean like an EJ 2.5?

@76-914 even the EJ series engines are antique (est.1989) designs now
