I wonder how god the 4 seasons ones are. I have a 4 seasons rebuild in my 1996 Fleetwood, and its been good for a few years. I use that car a lot more than my 1968.

I've never had a problem with their products. I've been using their products in all my old cars. The '47 has three of their motors in there since I converted to 12V. They were the only company that had the identical replacement as far as size, shaft diameter, and rotation to match the original 6V motors. Have one under the dash and two in the underseat heaters. Their catalog is quite impressive and highly detailed...

I would just say, I would NEVER go to the labor and expense to
replace a perfectly good compressor, open up and recharge a
refrigeration system, if all it need was to put a bearing in the
clutch. 

New stuff, it has caused me so many quality problems, I avoid
it in favor of good used original whenever possible.  Bruce Roe

FWIW I just timed the removal and replacement of the clutch, pulley and bearing replacement at just under an hour, working slowly with the correct factory tools.  That is with the compressor unbolted from the intake but left connected to the refrigerant lines.  Although in the past I had just about never seen a pulley bearing go out, it seems to occur with a greater frequency on the current run of rebuilds.  Apparently they are reluctant to replace the $30.00 bearing and are re using old and possibly failing ones.
I am currently working up a stock of pulley/bearing/clutch assemblies for my future use so when failure occurs I will be ready.

Can't deny it sounds a bit crazy, but I think it really only took me an hour as well, and I don't have all the pulley tools (only about half of them)...

Yes, if the rest of the compressor and its internals are fine, then undo the belts remove it from the intake and use the pullers to take the old clutch and pulleys out and replace whats bad. Absolutely no sense in breaking the lines.

Of course you need to be able to find the correct dual groove parts.....

Mike,
For some reason a couple of years ago when I wanted to buy a clutch/pulley assembly I found them hard to find.  It prompted a project where I collected a few single and double belt pulleys and bought some bearings.  I have a stock for what ever  I might need in the foreseeable future.   I think it is because at one time when a pulley needed a bearing they just discarded them and used another, leading to the shortage.

Yeah that's really the problem.  My autozone (right down the street) carries the compressor but not the parts!  I was actually thinking of taking the new compressor apart to swap pulleys and bearings as you suggest and keeping the rest of it but decided to swap and get the core charge back instead....
