Torqueflow Parts?
The fan clutch on my '83 300D has failed in the always on position. I'm looking for a replacement unit. Prices vary from $50 for the URO junk which I won't buy up to $250+ for a Behr unit. I've found a local supplier with one from an outfit called Torqueflow for $122. Is this brand any good?

The local supplier I mentioned was Autozoo. I generally avoid them, but sometimes they actually have worthwhile stuff.
I was doing some searching and found a suggestion that a stuck fan clutch can be rebuilt by taking it apart, cleaning it, and re-filling with gear oil. That was on a Datsun Z car site. Has anyone tried this with a Mercedes fan clutch? If I could just rebuild the old one I'd prefer to do that.

I got one at the local junk yard for a couple of bucks. It's been working great. That's always a crap shoot but probably at least as good as a new no-brand one for a fraction of the cost.

Japanese fan clutches are the few that I've seen that come apart making a refill possible, However gear lube would be too thick when cold ( fan locked ) then too thin when hot ( fan freewheeling). Liquid silicone is what the factory clutches use.
Off brands are an unknown. Sometimes you get actual auto manufacturer parts with the logo / part number ground off. I've bought 4 motor mounts from a off brand maker that were actual MB parts. However expect some consolidation, the sets were bought a few years apart for different cars, had the same number on the box but different part # on the actual mounts. Parts like this hit the market when an auto supplier / auto maker is clearing out inventory.

There is a temperature sensitive spring plate across the front. Remove that, underneath is a seal and a little pin. Remove both, you have access to the hole through which you can add silicone fluid. I went to a hobby store and bought a small bottle of silicone oil, I think it was 5000 cst or 3000 cst. Heated the fan clutch with a heat gun, allowed cooling action to pull oil in from syringe. Trial and error to figure out how much oil to add.
