Question about a broken a/c to alt. bolt

foyburgher · 08-03-2006, 07:28 AM

The bolt that connects the alternator to the air conditioning compressor broke on my '83 944. The head part of the bolt came out, but the back portion with the nut is still in there.

Here's the question: is the hole on the bottom of the alternator threaded or smooth inside?

In other words, the broken bolt has a smooth shaft with threads at the end. Does the bolt thread into the alternator hole or just thread into the nut?

Thanks for any help!!

Can you maybe take a picture.

I have an '86, I just pulled out the AC compressor and alternator, and found no single bolt that join both of them. They are both independently secured to the same bracket.

Yeah, they must have eliminated that A/C to alternator connecting bolt in the late models... I wonder why they got rid of it - maybe because it shears off!

I think I'll be able to screw the remaining portion of the bolt out the rear side with a pair of channel locks.

You were absolutely right, Legion. It was the Hayne's manual that led me astray by calling it the alternator to a/c bolt. They both bolt to the bracket, like you said. Now the fun begins, getting the broken bolt out of the mounting hole on the A/C compressor...

Is it the long bolt that secures the AC compressor to the bracket? That bolt is mostly smooth, but is threaded at the end and threads into the compressor itself. It seems to me that if you pull the compressor out of the car (you might even be able to leave the hoses attached) you would have an easier time getting at it.
