Engine 130 amp upgrade, helicoil

Alley Oop · Dec 19, 2018

When upgrading to a 130 amp, is there any advantage to installing a heilcoil in the alternator bracket instead of a
3/8 " bolt and nut?

I've always used a heli coil. Hole is even the correct size for the tap. Worked good every time. The advantage? Don't have to mess with a nut and personally, I think it looks cleaner.

It's an option, not an advantage.

I used a Heli-coil because I liked the way it looks

Use a bolt and then use a self-locking nut. That way you can be sure that it will stay in place.

I bolted it, but next time i'll helicoil. Just looks cleaner.

I simply drilled it one size and tapped 7/16. Mo advantage that I can tell but preference.
