I recently came across a Cincinnati No.3 that needs some major repair. Machine is not feeding due to a jammed hydraulic drive shaft. I'm having trouble looking for the correct manual and so far all the manuals that I have found has a different overarm compared to mine (see attached pictures). If someone can point me to the correct manual I would be grateful. Also I found two disconnected pipe fittings on the underside of the knee in feedbox compartment, as shown in the attached pictures. Anyone has any idea what these are for?

Wow that's a good find on that over arm. Unfortunately the owner replaced the geartrain removed with an inverter.
The 4J manual on Ebay is a hard hardcopy version though, is there a purchasable soft copy somewhere though?
On another note, does anyone know what's the HP on the rear bottom motor that drives the main pulley? I've read on this forum it could be anywhere from 20-50HP. That's a monster of a machine if that's true. Also can anyone confirm if the main hydraulic shaft is supposed to turn on motor start up?
 
anywhere from 20-50HP

For what its worth - the most powerful #3 K&T in 1957 was 30 HP - but the "ram" (fancy overarm) had but 15 for the main

Not exactly applicable since you have the HEAVIEST #3 made that year by CMM

Just that king size knee says that
 
The nameplate is located in such a tight space that I'd need an endoscope to read it. The owner is considering to replace it with a new machine but nothing seems to come close to that 70 years old machine in terms of power. Not for a big sum at least. I'm kind of tempted to buy his #3 but that torque destroyer VFD conversion puts me off.
