DO NOT MISALIGN THE SLEEVE TOO MUCH ANY ONE WAY, AS IT
WILL MARK THE CYLINDER BORE.
NOTE: The timing marks (the small punch marks on the
face of each gear), must be aligned for proper shaft
orientation. (See Actuator Timing.)
5. Install the shaft (2) into housing (1) by aligning the
proper punched timing marks. (See Actuator Tim-
ing.)
6. Temporarily tape the threaded portion of the shaft
will help installation past the shaft seals (masking
tape).
7. The end cap (5) is torqued to 40 - 50 ft. lbs. (54 - 68
Nm), such that the actuator begins rotation at
approximately 100 psi (6.895 Bar) pressure.
8. The end cap must be secured against the shaft by
installing axial set screws (4).
