Piston stroke ... 256.3 mm (10.1 inch)Note: The amount of air at the inlet port is multiplied by 6.6 in order to achieve the amount of hydraulic pressure at the outlet port. (1) Install the cylinder tube. The cylinder tube must bottom out. Maximum installation torque for the cylinder tube ... 14 N m (125 lb in) (2) Install end cap (2). Tighten end cap (2) until the end cap bottoms out on cylinder tube (1) . Maximum installation torque for the end cap ... 14 N m (125 lb in) Maximum breakaway torque for the end cap ... 88 N m (65 lb ft) (3) Torque for the purge screw ... 14 3 N m (125 26 lb in)Note: Turn out end cap (2) in order to align the purge screw with port (4) for the hydraulic reservoir. The tolerance for this alignment is 10 degrees. Do not turn end cap (2) more than one revolution. (5) Torque for the nuts ... 14 3 N m (125 26 lb in) (6) Torque for the bolts ... 10.5 0.8 N m (93 7 lb in) (7) Torque for nut ... 145 38 N m (107 28 lb ft) (8) Torque for the overstroke switch ... 7.5 2.5 N m (66 22 lb in)
