Can A/C clutch be re-built?
I am diligently working on correcting some issues on my 67 300SEL that was delivered to me last month after many years of storage. The car has a 72 280SE engine bored out to 3 liter, and was converted to 4-speed manual at the time of the engine swap.
My current project is getting at a clattering noise that is related to engine/belt speed and coming from the very front of the car. The main fan wobbled and could be wiggled with the engine stopped. I replaced the fan clutch and now it does not wiggle/wobble which is great. That was not the source of the clatter, however.
It appears the noise is related to the A/C compressor. When the A/C is turned on the clatter subsides (but is not gone). Interestingly, the tension of the V-belt slackens substantially when the A/C is engaged, even though no pulley or wheel appears to shift at all. The electromagnetic clutch appears to be doing its job as the hub spins when the a/c is engaged and stops when shut down.
Can I pull that clutch housing from the compressor and clean/re-build it, or is it a sealed unit that needs to be purcha$ed?
As always, thanks for your advice and input.
