Enerpac Pro TSP300 Serie Manuel D'instructions page 2

• Swivel kit model TSP300MK includes all items included
with the TSP300 kit, plus a new swivel post, four retaining
capscrews and two hydraulic port O-rings. This kit must be
ordered if the existing swivel post is worn or damaged and
requires replacement.
Hydraulic couplings are included with both swivel kits and are pre-
installed at the factory prior to shipment.
WARNING Always completely relieve hydraulic pressure and
disconnect both hydraulic hoses from the wrench before beginning
any of the following procedures. Be certain that pressure gauge
indicates zero (0) psi/bar. Unexpected release of hydraulic oil
under pressure may occur if these precautions are not followed.
Serious personal injury could result.
• Wipe all surfaces clean before beginning the following
procedures. Take every precaution to prevent dirt from
entering the wrench. Dirt entry may result in erratic wrench
operation and/or damage to wrench.
• The following procedures are to be performed only by persons
experienced in maintenance and repair of high pressure
hydraulic equipment, using appropriate tools, personal
protective equipment and shop facilities. Appropriate safety
procedures are to be followed at all times.
4.0 INSTALLATION - TSP300 SWIVEL ASSEMBLY
Refer to Figures 1, 2 and 3 during the following steps. Discard
old parts and replace with new parts from the kit as indicated.
1. Remove the circlip retainer ring (A) from the top of the swivel
post (F).
2. Using a pair of flat blade screwdrivers, gently pry the old
swivel assembly off of the swivel post (F).
3. Inspect the swivel post (F) for obvious signs of wear or
damage.
• If the old swivel post is in good condition, it can be reused.
Continue with steps 4 through 9 of this procedure
• If old swivel post is worn or damaged, replace it as described
in the instructions in Section 5.0. Then, continue with steps
4 through 9 of this procedure.
4. Check that the four socket head capscrews (D) securing
the swivel post are tight. See Section 5.0, step 6, for torque
values.
5. Remove the old O-ring (E) from the swivel post (F) and
replace it with a new O-ring (E) from the kit. Coat the O-ring
with silicone grease before installing. See Figure 2 for
location.
NOTICE If O-rings (C) are pre-installed in the swivel manifold
block (B8), skip step 6 and go to step 7.
6. Install two new O-rings (C) from the kit into the grooves of
the swivel manifold block. Coat the O-rings with silicone
grease before installing. See Figure 3 for locations.
7. After installation, coat all O-rings with a small amount of
additional silicone grease. Carefully slide the new TSP
swivel assembly (B) onto the swivel post (F).
8. Install a new circlip retainer ring (A) from the kit onto the
swivel post (F).
9. Connect hydraulic hoses and cycle the wrench at 1,000 psi
[69 bar] to check for oil leaks. If there are no leaks, cycle the
wrench at 10,000 psi [690 bar] and check again for leaks.

5.0 INSTALLATION - TSP300 SWIVEL POST
Refer to Figures 1, 2 and 3 during the following steps.
1. If not already done: Remove the circlip retainer ring (A) from
the top of the swivel post (F). Using a pair of screwdrivers,
gently pry the old swivel assembly (B) off of the swivel post (F).
2. Remove the four socket head capscrews (D) securing the
swivel post (F). Gently pry the swivel post (F) from the drive
unit or wrench housing (H).
3. Wipe clean all surfaces of the drive unit or wrench housing
(H). Then, apply a small amount of Loctite 243 thread sealant
in each of the four threaded bolt holes (
wrench housing (H). Be careful not to drip sealant into the
hydraulic ports.
4. Install two new O-rings (G) into the ports on the base of the
new swivel post (F). See Figure 2 for O-ring locations.
5. Place the new swivel post (F) on the drive unit or wrench
housing (H), making sure that hydraulic ports are aligned. Be
careful that O-rings (G) do not drop out or become pinched
or cut.
NOTICE In the following step, be sure to use the new socket
head capscrews (D) provided with the TSP300MK kit. Before
installation, be certain that capscrews are clean, and free of oil or
grease.
