GM Alternator Nightmare!

I bought an alternator conversion bracket from one of our vendors. I was desperate to get my Sammy back on the road with a new GM alternator. I made the conversion outside in the winter, I was in a hurry. Turns out the bracket was designed or built wrong, and it set the alternator back 1/4" too far. It also did not have clearance for the dipstick, or the bottom alternator bolt. Did I find and fix the problems when I put it on? NO! I broke the dip stick. Would the fan belt tighten down? No, because the alternator would not swing on the bracket. Did I use the prescribed alternator? Yes. Did the alternator break when I put the pry bar too it? YES! So did the upper alternator bracket tab on the water pump. I forced a second alternator in there and sprayed the belt with a gooey dressing, jury rigged a top bracket, and drove it for 5000 miles before the water pump decinigated because of the sideways stress on the fan belt, (1/4' out of line and a short span of belt between the water pump pulley and the alternator pulley). I pulled the radiator to work on it this time. That's when I discover the bad design on the bracket. I had to grind the bracket for clearance around the alternator, and dipstick. I had to shim the alternator pulley out to its max. The loss was one alternator, one water pump, one dipstick tube, a two mile walk, one tow <nobr>truck</nobr> ride, and about 12 hours of wrench time! The vendor shall remain anonymous, 'cause I'm going to try to blackmail them at a later date.

Re: GM Alternator Nightmare!

I had the same problem with the gm bracket. I had to cut and weld to fit correctly. I had to use a ford alt slip bracket so I had the proper adjustments. The stock bracket would not even come close to working. [img]images/graemlins/RockOn.gif[/img]

Re: GM Alternator Nightmare!

I got the GM bracket from TT it took a little to get it lined up.. I had to elongate the holes in the bracket were it bolts to the side of block and space the one bolt on the front with a two washers..it lined up good then..

Re: GM Alternator Nightmare!

That sucks the bracket wouldn't line up properly. I don't know enough about zuke engines to know if there's differences in the mounting points or not that would cause a bad fit, someone like Sarge would know probably.

Realistically you probably can't expect the vendor to cover more than the replacement of the faulty bracket.

Re: GM Alternator Nightmare!

I got mine from TT and it fit perfectly. I ground out the stock sami bracket a little bit to fit over the top and allow it to adjust and have had no problems. Lines up perfectly.

Re: GM Alternator Nightmare!

I was putting the TT bracket on a swift GT bottom end, that should not make a difference..But maybe something could just slightly be off from the sami block and it would cause the bracket to be off by a smig.

Re: GM Alternator Nightmare!

I am not bashing anyone but the bracket came from TT. I also did not call them about a chance to fix it. I just fixed it myself. [img]images/graemlins/RockOn.gif[/img]
