Huge IBM 1800 find (and need some help)

OK, a quick search shows the 2311 was indeed hydraulic! (The following comes from my knowledge of the 2314, but it is likely to be similar.) These had a Cessna hydraulic pump belt-driven by the same belt that turned the spindle. Short hoses connected it to a big tank at the back. This acted as the fluid reservoir as well a a housing for the servo valve and the linear actuator. It is very likely the seals on the pump, valve and actuator have deteriorated, and the hoses are cracked and brittle. If you were to fire it up, the hoses might blow, and spray oil all over the inside of the drive. This has happened at the two installations I was at, while under IBM maintenance in the early 1970's. It caused a lot of damage. Jon
