Piston stroke ... 184.7 mm (7.27 inch)Note: The amount of air pressure at the inlet port is multiplied by 6.6 in order to achieve the amount of hydraulic pressure at the outlet port. (1) Torque for the overstroke switch ... 7.5 2.5 N m (66 22 lb in) (2) Torque for the purge screw ... 14 3 N m (10 2 lb ft)Note: Turn out end cap (3) in order to align the purge screw with port (5) for the hydraulic reservoir. The tolerance for this alignment is 10 degrees. Do not turn out end cap (3) more than one revolution. (3) Install end cap (3) on cylinder tube (4) . Tighten end cap (3) until the end cap bottoms out on cylinder tube (4) .Maximum installation torque for the end cap ... 14 N m (10 lb ft)Minimum breakaway torque for the end cap ... 88 N m (65 lb ft) (4) Install the cylinder tube. The cylinder tube must bottom out.Maximum installation torque for the cylinder tube ... 14 N m (10 lb ft) (6) Torque for nuts ... 14 3 N m (10 2 lb ft) (7) Torque for bolts ... 7.9 0.6 N m (70 5 lb in) (8) Torque for nut ... 145.5 37.5 N m (107 28 lb ft)
