Just curious to know if anybody has ever had this happen and if you could think of some sort of fix to get back to civilization.

Alternator bracket broke
- Thread starter DRYANKNPULL

Don't use electrical accessories and drive straight home.
How far do you have to go, and how good is your battery? I've had one bad alternator and one belt break, I didn't even notice until electrical accessories started acting weird. Voltmeter on the carbed truck read 10 volts before I started to notice an issue.
EFI truck started to overheat as the electric fan relays stopped working properly.

I realized it pretty quickly when I didn’t have power steering. I’m not sure I could get the belt to work without the alternator.

Pick up a chrome aftermarket replacement from the autoparts store? ( cause that’s all there is?)
Probably what I’ll have to do. Waiting for the parts store to open. The alternator went out about a month ago late on a Sunday evening. I was a couple of miles from the Chevy dealership and left it there. They put a new one on for me the next day. They either didn’t put the rear bolt in or it fell out. The two front bolt housings sheared off. Guess I should have inspected the work better.
I had an alternator bracket break on a several hundred mile drive between duty stations in western Wyoming. Thought I was saved because there was a GM dealer in town but they didn't have anything. They sent me to a local welder who was able to fix it for me.
I only caught it because I'd exited the interstate for gas and the throttle stuck. Popped the hood to fix it and noticed the alternator was flopping around barely held in place.

Everybody can get the bracket by the end of next week. I just made the wrecker driver’s weekend.
What truck? What belt system?
I have never had one break. One gen1 sbc v belt. Nor do I remember a bracket failing on a serpentine belt. Plenty of alternators seize and stop engines on the serpentine.

It’s a 1990 suburban. Stock 350 with the serpentine.
I suspected when you said the pa stopped.
Does that alt still spin?
Lazy mechanic that leaves bolts and braces off. I would definitely complain to the shop that did that repair.
Wrecking yard for bracket ?
Summit racing will say 3 - 4 days delivery but most times I get stuff in 2

had a gm serp setup like this going on 15+ years with a cs144 upgrade alt and a fisher plow hydro pump off the same area . no rear brace and not 1 problem .
if you have it welded get someone who can TIG it NOT spool gun mig it as that wont hold . if you need to pull the bracket the p/s pulley has to be pulled . then the p/s pump removed for the bolt going in to the side of the block .
and same bracket off a 4.3 v6 in the s10 blazers .

My suspicion is the new alt seized, w/o that rear brace the bracket broke.
My alternator seized and broke itself and the bracket. What brace are you referring to Wes? I know there isn’t any rear brace on mine. I didn’t know there was supposed to be one?
Now I started looking and found one on eBay. It sure looks familiar. Now I need to go check mine.

this is the bracket they are referring to and i am going to put it back on......
It looks like the rear mounting ear has been broken for a while. The break is dirty, unlike the front one. Not saying that one would necessarily notice it.
But what's with the cupped washer on the lower bolt? Could it have put pressure on the bracket ear instead of just the sleeve when the bolt got tightened?

I have a spare accessory set off of a 95 1/2 ton burb with auto trans that I have sitting in the back of the warehouse at work... came off a complete engine that i bought for the long block. i had to strip it down and the exhaust, pulleys, brackets, and whatnot are just sitting back there in a big box. My Blazer now uses brackets out of a buick roadmaster to fit a bigger alternator from a cop car... the stock brackets and accessories wont work in the blazer without a lot of backwards engineering now.
FYI: I have the adapter/extension cradle thing for the bigger alternator, and the rear ear has broken. I have the rear strut rod connected- not sure how it broke- doesn't appear to be going anywhere or breaking the front tabs, but I need to source another adapter cradle or have mine welded. (or find a tiny stock alternator and different belt for emergency use and just remove the cradle?)
If you get in a tight spot let me know- have been going back and forth about putting all the accessories up for sale locally, or putting all of it in the dumpster at work -just to not have to deal with craigslist people over a few bucks.

I've had a few of those welded up. It is not uncommon.
