MAINTENANCE SECTION
6. Using a socket, thread the end cap (7), O-ring leading, into the bore of the housing and tighten.
7. Install uniswivel O-rings and uniswivel (USS for TXU-2 or USL for TXU-4 & TXU-8), tightening
uniswivel post screws (20) in a cross pattern. Apply non-permanent, thread-locking compound to
the threads.
8. Apply moly grease to the face of the sliders and the notch in the piston.
ASSEMBLY OF THE RATCHET LINK
1. If the side plate sleeves (12) were removed, press new sleeves, shoulder end trailing, into the right
and left side plates (1 & 2) from the inner face of the side plates. Make certain the sleeves are
square with the side plate faces and the shoulder of the sleeves enters the recesses in the side
plates and are pressed ush with the faces.
2. For Series TXU-2, TXU-4, and TXU-8 models: Position the upper spacer (8) against the inside
face of the right side plate. Apply a non-permanent thread-locking compound to the threads of the
two upper spacer screws (15) and secure the spacer with the screws through the side plate. For
Series TXU-16 and TXU-32 models: Press the spacer roll pin (19) into the right side plate with
one end of the pin ush with the external face of the side plate. Insert the tab of the upper spacer
(8) into the slot in the middle spacer (9), and after aligning the holes in both pieces, install them on
the spacer roll pin (19). When they are correctly positioned, apply a non-permanent thread-locking
compound to the threads of the two upper spacer screws (15) and secure the spacers with the
screws through the side plate.
3. Insert the two lower spacer pins (11) into the holes in the lower edge of the right side plate. Apply a
non-permanent thread-locking compound to the threads of the lower spacer screws (16) and secure
the pins with the screws through the side plate.
4. Place the lower spacer (10) over the pins against the side plate. Make certain it is correctly oriented
so that no part of the spacer extends beyond the edge of the side plate.
5. Insert the drive pin (4) into the small cross-hole and slot in the drive plate (3). Invert the plate
causing the ends of the pin to enter the slot and move the pin to the narrow end.
6. Position the drive pin spring (5) in the drive plate slot with the two non-connected ends between the
drive pin and the large hole in the slot. Position the closed end of the spring on the opposite side
of the pin. Then, apply pressure on the spring to align the hole through it with the hole in the drive
plate for the drive pin spring roll pin (18). Insert the spring roll pin into the drive plate, through the
spring and into the far wall of the drive plate.
7. Wipe a thin lm of Marine Moly Grease onto the inner face of the large opening in the drive plate.
8. Position the ratchet (6) in the central opening of the drive plate.
9. Insert the drive segment (7) into the opening adjacent to the ratchet. Make certain the teeth of
the ratchet correctly engage the teeth of the drive segment. Reverse the ratchet if they do not
properly engage.
10. Slide the drive segment sideways to expose the spring hole. Install the segment spring (14) into the
hole. While compressing the spring, slide the drive segment inward until the drive plate captures
the segment spring.
11. Apply a light coat of Marine Moly Grease to both sides of the drive plate and drive segment as well
as the inner faces of both side plate sleeves (12).
12. While keeping the assembly together, insert the hub of the ratchet into the side plate sleeve of the
assembled side plate.
In the following step, an excessive amount of grease will prevent
proper tooth engagement between the ratchet and the drive
segment, causing the tool to malfunction.
