18. Using the far, top tie-rod, attach cylindrical
spacer (114) to the right side of the assembly.
19. Attach one hexagonal spacer (113) to the other end
of the tie rod. Do not tighten.
20. Attach one hexagonal spacer to each end of the bot-
tom, near tie-rod. Do not tighten.
21. Secure the assembly to a flat surface using two
c-clamps, or other strong clamping devices, to pre-
vent the assembly from twisting. The assembly will
remain secured to the flat surface for the remainder
of the assembly procedure.
22. With the assembly secured, torque the spacers
against each other to 15 ft-lb (20 N•m).
Installing Lube Adapter
23. Push o-ring (121) into the inside groove of the cylin-
der lube adapter (120).
24. With the lip of the adapter facing left, slide the
adapter onto the left end of the hydraulic piston
shaft.
Installing Hex Clevises and Baffle Jam Nut
25. With the hex-side of the baffle jam nut facing away
from the hex-head of the clevis, spin the baffle jam
nut (122) onto the hex clevis (117). Leave one to
two threads between the head of the clevis and the
nut.
26. Apply high strength thread sealant (124) to the
threads of both hex clevises (117).
27. Apply primer (123) to the threads with the thread
sealant.
28. Attach modified bushing (118) to the activator
plate (119).
29. Insert the clevis (117) without the baffle jam
nut (122) into the corner hole of the activator
plate (119).
30. Slide the modified bushing over the cylindrical
spacer (114) and screw the clevis (117) into the
right end of the hydraulic piston shaft (104).
31. Spin the clevis (117) and baffle jam nut (122) onto
the left end of the hydraulic piston shaft finger-tight,
ensuring a gap of one to two threads between the
baffle jam nut and the head of the left clevis.
32. Rotate the right clevis until the cross-holes form a
vertical line.
In the following step, the port holes need to be fac-
ing down, with the cylindrical spacer (114) facing
right.
