9. See Figure 17. Lift off the swivel post. Remove and
discard the post and port seals.
Clean and inspect all components including the
hydraulic couplings. If the hydraulic couplings are
damaged, remove and replace (swivel yoke threads
are ¼” NPT). Inspect the components for scoring,
pitting and damage, which could impair the sealing
ability and replace as necessary.
Multiswivel Manifold Assembly
NOTE: All seals should be new and lubricated with
clean hydraulic oil or seal assembly paste before
installation.
1. Install the new port o-ring seals into the base of the
swivel post.
2. Apply Loctite® 243 or equivalent to the four screws
and attach the swivel post to the wrench body.
Torque the screws as follows.
• TWHC1 & 3 (M4) – 5.1 Nm (45 in-lb).
• TWHC6 (M5) – 10.2 Nm (90 in-lb).
3. Assemble a new o-ring seal to the swivel post.
4. Assemble four new o-ring seals to the banjo.
5. Carefully push the banjo onto the swivel post
ensuring the seals do not get nipped.
6. Attach the banjo circlip to the post.
7. Assemble a new o-ring seal into the advance and
retract yokes.
8. Assemble the advance and retract yokes to the
banjo ensuring the seals do not get nipped.
IMPORTANT: See Figure 18. Ensure the advance
and retract yokes are installed correctly onto the
banjo. The banjo and advance yoke are engraved
with A (advance) to indicate the correct position
of the respective yoke. Reversal of the yokes will
cause the torque wrench to malfunction and can
lead to damage.
9. Rotate the yokes around the banjo until the keyways
engage.
10. Clamp the yokes together by installing the yoke
screw and torqueing to 5.1 Nm(45 lb-in).
11. Check the operation of the multiswivel manifold by
rotating and tilting, movement should be free and
smooth.
