took my alt off a few times awhile back and one of the metal cups came off
of the bushing and got lost so i subed a metal washer up aginst the bushing and the bolt head. Over time the bushing weared out causing belt to loosen. Some how
going around 75-80 mph either the bushing gave out or something..anyhow
the belt flew off or busted. Causing the gasket to blowout on head..
just waiting on the head gasket to come in monday somtime around noon.
Then ya see we will take the honda back down to where the car is and ill put it back together and drive home. Haven a great time Im gonna take some pics of the mzda rx7 with the 327 being hooked up by junior there.
theres also a few early beamers there 3 different modlees ones a automatic
there all in great shape and run like fast although one is also down with what seems to be a fuel relay prob. Man the cyl. heads on these beamers
are like huge ones carbed its the automatic im pretty sure. Ill take a pic
for your enjoyment the owner claims it loves to run in the 100 + range.

Hey Joe, I got sick of that poor alternator bracket set up and and fabricated my own out of aluminum. Those bushing over time wear out and cause the whole alternator to flex when you rev your motor. A good design initially, but is prone to failure over time.

Anyone know if the alternator bracket bushings are still available?

Dealer or parts place?

Thanks for the info JB. Sounds like the mounting bracket parts were also used on the Audi Quatro oil cooler mountings. I'll check the Audi dealer.

And thanks fro the informative link!

I got new bushings from the local Porsche dealer, I think they got them in from Germany for me (like most of the parts I buy of them).

The Canadian fix for the lower alternator mount bushing is to drill out a hockey puck. I purchased a new bushing from the dealership but wasn't happy with the movement this soft rubber bushing allowed. Remembered an old posting from a fellow Canadian suggesting the hockey puck fix and thought I would give it a try. The harder rubber seems to provide the necessary shock absorption and prevents the alternator/belt from bouncing around as much.

I am going to be rebuilding my spare engine soon, and I am thinking about fabbing up a new bracket top and bottom, the bottom one will definatly be tightened by a pull bolt system, I am sick of having to pry it out.

I also did the hockey puck fix for the lower bushing, works great, keeps the alternator much more stable.

Well, I didnt need to go the porsche or Audi dealer. Once I got into it, I figured I could fab something up. My main problem was the upper bracket.

I used lawn hose washers and rubber tubing I had. Just so happend to be the right sizes; worked like the grommets but much stiffer. Alternator still has give, but stays in alignment. Worked great and looks fine.

When in doubt....fudge it.

Does anyone have a picture of the hockey puck fix ?

The rubber bushings used in several places under the hood as someone else has already pointed out.

However, Porsche superceeded the use of the rubber bushing as alternator bushings over 15 years ago.

The part that Porsche has been suppling since before 1987 is a translucent yellow nylon or plastic. This seems to be a permanent fis, since I have not replaced a since alternator bushing after switching to the new parts.

If you buy parts from a Non-Porsche Dealer supplier, make sure that they don;t give you the old rubber part. I know that many of the aftermarket places are still selling the rubber parts.

I put mine in today yup got to use my craftsman tools too
one word ..nice they fit right there under the big bracket I had to loosen it up and move it back to get the alt to fit inbetween the new bushings. I had the top bolts in just the bottem adjusting bolt out and the belt off. Had to remove the alt to begin with because I punctured an oil filter if you can believe that.

How about some pictures of this "Hockey Puck" fix.

Any other suggestion of what to use? Was there a specific reason Porsche used rubber bushings for the Alternator Mounts? I am thinking about taking what I have of the bushings, and having some non-rubber variations manufactured.

The problem is that my original rubber ones merely deteriorated from some oil sitting on them. I ended up ordering a new Bracket Mount set with the bushings attached, but one of the Brackets is not correct, but I believe the bushings that are in it will work for the bracket that is already installed.

I may have to pull my engine anyways, in order to clean up all this goddamn oil that split, and is sitting on everything.
