finger tight. Then, wrench tighten these
parts an additional 2 to 3 turns beyond
finger tight.
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 drive unit.

• 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).
• Reinstall the circlip retainer ring (A).
• Connect hydraulic hoses and cycle the
drive unit at 1,000 psi [69 bar] to check
for oil leaks. If there are no leaks, cycle
the drive unit at 10,000 psi [690 bar]
and check again for leaks.
WARNING
Pressurized hydraulic oil
can penetrate the skin and could cause
serious personal injury. Always repair any
oil leaks before using the wrench.
• Apply a small amount of Loctite 243
thread sealant to the threaded holes in
the drive unit. See (✽) in Figure 14 for
locations.
• Install two O-rings (G) into the ports on
the base of the swivel post (F).
• Place the swivel post (F) on the drive unit
(H), making sure that hydraulic ports are
aligned. Be careful that O-rings (G) do
not drop out or become pinched or cut.
•
Install the degreased socket head
capscrews (D) and tighten them as follows:
a) W2000X and W4000X:
(M4 capscrews) – 3.7 Ft.lbs [5.1 Nm]
b) W8000X and W15000X:
(M5 capscrews) – 7.5 Ft.lbs [10.2 Nm]
• If the drive unit is equipped with the
optional TSP300 Pro Series swivel, refer
to Enerpac instruction sheet L4119 for
additional reassembly instructions.
