I have the compressor separated into four major parts. The nose piece with the shaft seal has three countersunk phillips heads screws which I can't get removed. I used a heat gun on them, bit with ratchet, and a hammer and impact. I applied enought heat to the nose piece that any locktite should have let go. All I've managed to do is distort the screw bit recess. Other than drilling out the screws and re-tapping the threads is there anything else I could try?

Worst case would be to get a rebuilt compressor, any suggestions on them?

Thanks,
Glenn

Hey Glenn,

There's a 993 guy (IIRC) that has a website where he shows pic on how to rebuild a compressor. Worse case scenario you can buy a reconditioned one for around $200. Do a search on the Denso #.

I'm pretty sure the compressor is a standard model. The only thing that changes from model to model is where the mounting ears are.

 

John,
I found rebuilding instructions on the Pelican website. The damn screws wil not come out. May have to go the rebuilt route even though I have the seal set.

I went to Hershey yesterday to see the vintage car hill climb and show. I just want the 928 done so I can drive it!

Cheers,
Glenn

 

Reverse drill bits and chase threads.. Clean very well.

Zues,
Thanks, do you happen to know what size they are?

I never noted size, always got them out. Most likely 6mm or 8mm. You might get lucky when reverse drilling and be able to measure one. Usually when you drill a tapered head fastener the head pops off first. Sometimes you can unscrew whats left fairly easy.
