Lex, I went back through the thread looking for details on the clutch and found none. Can you tell us about it please?

Lex, I would also appreciate it if you posted photos here rather than links to photobucket.

Click on the image icon, and select "from computer" instead of url. select the files you want, you can do multiple files at the same time.. Click upload. The images will appear in thumbnail size in the body of the message
then when someone wants a closer look they click the thumbnail to open the image in a lightbox.
As a demo..
Hope that helps..
Very interested in following your progress with the SG, looks good.

I find the thumbnail pictures a pain to view, having to open each one and waiting for it to appear. If it is OK with the moderators I will continue to use Photobucket.

Be aware though, that if you ever remove photos from Photobucket or delete your account, threads like this become pretty useless. There are a number of old threads on Practical Machinist that have broken links to photos that were hosted on external sites, severely reducing the value of the information posted.

http://www.woodworkforums.com/f65/di...ajesty-180755/ thread started by Michael is a case in point as are Steamwhisperer's presentations.
It is however your choice in the end.

Good point about the broken or old links PDW, I will try inserting images for the first time here.
Bryan, the Electo-magnetic clutch is just a 12volt unit for an automotive a/c compressor. This clutch is about 120mm diameter.
I wanted to use this one from a Falcon because the diameter (100mm) was almost the same as the original but the direction of rotation was wrong and the V grooves were inappropriately placed for my application.

I have to ask the question "how do you get an a/c clutch that operates in the other direction?"
Does the motor it came off run in the opposite direction to the Falcon? A/c unit turned around 180deg? I have to say I have not yet experienced this, but I have not worked on any of the newer Asian brands etc. Ford and Toyota are my limit in recent (A/C equipped) years.

I added a second sanden AC compressor to my Prado for on board air, I had to remove the clutch off the existing compressor and machine and weld in a second pulley. From what I recall the clutch came off easily, no need for a puller.

"Spot the difference" in the 2 photos to see why I had to use the large black clutch to get the correct direction of rotation
PDW depending on the age and brand of compressor you have, it may have a tapered shaft. but the modern ones are just a parallel shaft with a square section key. The Sanden type (right photo) usually come off pretty easily, as argeng pointed out, because the armature air gap has to be adjusted by shims whereas the unit in the left photo requires a special puller because the armature is pressed onto the shaft, to achieve the gap, and retained by a locking nut.
This is a puller I made years ago, to remove the armature on a friend Rolls Royce A/C compressor, which I modified a few weeks ago by cutting a 22 x 1.5mm thread on the other end to allow the removal of the very tight black clutch.

Maybe I should have asked why does the black clutch run in the other direction?

Might be time to investigate the wreckers....
