Figure 4, Hydraulic Coupling Replacement
Install new hydraulic fittings by hand. Then, use a wrench to
tighten them. Follow steps 6 through 9.
5. Coat the threads on both ends of the adaptor (B2) with
Loctite 577 thread sealant. Thread the male coupling (B1)
onto one end of the adapter (B2). Thread the other end of the
adaptor (B2) into the advance port (marked "A") of the swivel
(B).
6. Tighten the coupling (B1) and adapter (B2) by hand, until
they are each finger tight. Then, wrench tighten the fittings
an additional 2 to 3 turns beyond finger tight.
7. Coat the threads on the swivel end of the female coupling
(B3) with Loctite 577 thread sealant. Thread the coupling into
the retract port (marked "B") of the swivel (B).
8. Tighten the coupling (B3) by hand, until it is installed finger-
tight. Then, wrench tighten the coupling an additional 2 to 3
turns beyond finger tight.
9. Allow sealant sufficient time to cure (refer to NOTICE
statement after this step).
NOTICE To allow the sealant sufficient time to cure, wait a
minimum period of 3 hours at 68 to 104°F [20 to 40°C], or 6 hours
at 40 to 68°F [5 to 20°C] before pressurizing the wrench.
10. Coat O-rings (E and C) with a small amount of silicone
grease. Then, carefully slide the swivel assembly (B) onto
the swivel post (F).
11. Reinstall the circlip retainer ring (A).
12. Connect hydraulic hoses and cycle the wrench (or drive unit)
at 1,000 psi [69 bar] to check for oil leaks. If there are no
leaks, cycle the wrench (or drive unit) at 10,000 psi [690 bar]
and check again for leaks.

any oil leaks before using the wrench.
7.0 REBUILDING THE SWIVEL ASSEMBLY
Rebuild the swivel assembly as described in the following steps.
Refer to Figures 1 and 5.
1. Remove the swivel assembly from the swivel post and
remove the hydraulic fittings from the swivel. Refer to steps
1 through 4 in Section 6.0.
2. Loosen and remove socket head capscrew (B9).
3. Firmly rotate swivel arm "A" (B4) and swivel arm "B" (B5) in
opposite directions until they become disengaged from each
other.
4. Firmly pull swivel arm "A" (B4) and swivel arm "B" (B5) off of
the posts of the swivel manifold block.
5. Remove and discard O-rings (B6 and B7).
NOTICE Inspect all components before reassembly. Always
replace any worn or damaged parts with new parts. Remove any
dirt, old grease or old sealant from reusable parts and make sure
that they are clean.
6. Install a new O-ring (B7) into the groove on each swivel arm.
Apply silicone grease to O-rings as installed.
7. Install new O-rings (B6) into the grooves on the posts of the
swivel manifold block (B8). Apply silicone grease to O-rings
as installed.
8. Reinstall swivel arm "A" (B4) and swivel arm "B" (B5) on the
posts of the swivel manifold block (B8).
9. Rotate the swivel arms (B4 and B5) toward each other until
the tabs are fully engaged in the notches.
10. Coat the threads of the socket head capscrew (B9) with
Loctite 243 thread sealant. Tighten the capscrew securely.
To allow the sealant sufficient time to cure, wait a minimum
period of 3 hours at 68 to 104°F [20 to 40°C], or 6 hours at
40 to 68°F [5 to 20°C] before pressurizing the wrench.
WARNING Capscrew (B9) must remain tightly installed.
Never operate wrench with capscrew (B9) loosened or missing.
Serious personal injury and/or damage to wrench components
may result if swivel arms become loose and/or separated while
the wrench is under pressure.
11. Reinstall hydraulic fittings and reinstall the swivel assembly
on the swivel post. Test for proper operation. Refer to steps
5 through 12 of Section 6.0 for instructions.
