Thanks for the O Ring Cap'n.
Now I got a major problem. I hooked everything up, and cranked the engine without sparkplugs, to get oil pressure. I heard a pop, and lots of acrid smoke. I opened the garage door, took a deep breath, and ran back in to disconnect the battery. When the smoke cleared, I looked under the car. The hot wire to the brand new alternator was totally melted, taking the wire harness from the alternator to the starter and fuse box with it. WTF? Could the new alternator be bad? I guess I'm lucky I got the battery disconnedted before the car burned down, I could hear the fuel pump working perfectly. But I am very frusterated right now. I gotta walk away from this car right now. I really wanted to drive it to Ventura next week, and I thought I was just a spark plug install from starting it. But, prolly the alternator at least has to come out. I have to work the rest of this week. I am pretty upset right now, but I'm wondering what I did wrong. I put everything back the way I took it apart. It's a brand new Bosch alternator I got from Tom and Wayne last time I was in LA. Cap'n if you see this give me a call, please.

There was a thread about rebuilt alternators with the wrong hot lug on the back of the alternator. The positive lug is too long and makes contact with the back cover of the alternator.

bernard, when you pull the alt, remove the rear cover and look for an arc point. there was a thread long ago regarding a stud on the rear of the alt making contact and the need for denting the rear of the cover out at the stud contact. i think one member cooked a few alts before figuring it out.

I read the that Technical Bulletin and it says remove the two and make it one

Eliminate aluminum seal 021 101 341A between cylinder and cylinder head.


Eliminate paper gasket 021 101 341A between foot of cylinder and crankcase.


Install 1.6mm aluminum shim 071 101 341, with adhesive D 000 400 at foot of cylinder to compensate for removed paper gasket and aluminum seal. Illustration 1.

It sounds like your just removing the paper gasket and installing a thicker Gasket

Oh this is fo 2.0 type IV 75-83

I could have the long alternator hot bolt problem. That alternator wire was in good shape when I ran it back thru the tin. It didn't chaff thru while cranking. I have to remove the alternator and I need a new alt. wire harness. I'm gonna take the rest of the day and relax. I been floggin like crazy to get this car ready for next weekend. Maybe I can still make it, but I'm spending the rest of Labor Day with my wife.

Oh my gosh! That's exactly what happened. The washer under the black wire, grounded to the cover. It looks like somebody took to it with an arc welder. Go to my picturetrail site and check it out. If someone can post the picture, I would appreciate it.

The alternator on the top is the brand new Bosch unit. The bottom one is the old unit. You can see that there is a new black box with a wire coming out of it. That wire is connected to another post with a washer and screw. The washer contacted the cover. You can see on the cover picture, it dang near burned thru. The alternator harness is toast. A warning should come in every Bosch Alternator box about this.
Everyone in Hell prolly has to remove a 914 alternator, with the engine in the car, once a day. What a PITA. I bet it's a whole lot of fun putting it back in.

I don't think it is a new alternator. It must be a rebuilt. I think Jeff Bowlsby sells a new alt. harness fairly cheap.

Tom couldn't find me a new alternator wire harness. Anybody got a good used one? Cap'n, or Mike Z? If I don't find one by tomorow, I'm out of luck on driving down Saturday.

I've got one on my spare 2.0 motor. Swing by the shop & we'll take it off. Just replace it later. Mark
