My #7 Beaudry does not have a specific place to oil the clutch surfaces that I know of. The main bearing is chambered for oil. I have a drip oiler on that bearing which flows at about 3 oz. per 8 hour day. A little bit of oil seeps out of the front of the bearing. The rest flows out the back where the 2 parts of the flywheel and big drive wheel nest together. I squirt some oil on the roller arm assembly located behind the clutch twice a day and put a shot of grease in the zirk on the outboard end of the big drive pulley.
I'm still not positive if the clutch runs wet or dry as I have not actually taken that part of the hammer apart.
As well built as these machines are, I can't imagine that the designers left out such an essential detail. I suspect that the clutch gets what lubrication it needs through the main bearing.
The cone clutch on my 100# Little Giant is metal on metal and I keep it wet with a mix of 30# oil thinned 60 % with diesel.
Whatever the answer is, the way mine is set up is working very well, My 200# hammer has excellent control. I have been forging long hollow tapers in pipe , freehand on a set of flat dies , something that is only possible on a hammer with very good manners.
I have never run any other hammers than my own, so I don't know how other machines behave.
