5.4.2 SPA Actuator Assembly Instructions
Assemble the actuator as follows while referring to
. Read the instructions thoroughly before
assembling the actuator.
1. Apply a small amount of
Mobilgrease XHP 462
to both sides of the outer tube gasket (17). This will aid in installation
and prevent damage to the gasket during the assembly process.
2. Install the outer tube gasket (17) into the housing (1).
3. Install the translating tube subassembly (consisting of items 29, 20, 19, 18, 23, 21, 22) into the housing (1).
NOTE: The translating parts kits listed in this manual come pre-packed with grease.
4. Apply a generous amount of
Mobilgrease XHP 462
to the thrust washers (24) and thrust bearings (25) and assemble
them over the gear spacer (22).
5. Aligning the keyway in the output gear (26) with the key (23) in the screw (18), assemble the output gear (26) on the
screw (with the counterbore in the gear facing up, away from the thrust bearing set).
6. Clamp the screw (18) between a soft-jawed vise and then thread the spacer nut (27) on the screw (18) and tighten it
against the output gear (26).
NOTE: The spacer nut flange should be in the counterbore of the output gear.
7. Check the alignment of the tapped holes in the spacer nut (27) with the holes in the output gear (26). Use two 9/64" Ø
pins approximately 1-1/2" long. One pin should drop into the hole in the output gear (26). If the pin does not drop into
the hole, tighten or loosen the spacer nut until the hole is aligned and one pin drops into a hole.
NOTE: The spacer nut should not be rotated more than 22-1/2° before the pin drops into a hole in the gear.
8. Remove the pin from the aligned hole. Install the half-dog set screw (28) and tighten the half-dog point into the hole
in the output gear (26). Remove the remaining pin and proceed with the assembly.
NOTE: One hole must be in alignment to achieve proper assembly.
9. If necessary, rotate the lifting nut (20) to position it approximately 4-1/2" to 5" from the flat washer (21). This will
allow room to properly install the outer tube (31) without jamming the lifting nut (20) into the flat washer (21) during
the following outer tube (31) installation process.
10. Lightly grease the outer diameter of the translating tube (29) and place the outer tube assembly (31) over the
translating tube (29).
NOTE: Align the keyed features located on the ID wall of the translating tube (29) with the corresponding keyed features
located on the OD of the lifting nut (20).
NOTICE
Be sure all components are clean and dry before assembling.

Do not grip on the bearing journal of the spacer nut when tightening the
spacer nut.
