To install:
1.
Inspect SaverLok connection (1) for damage.
Coat threads with clean TJC.
2.
Coat SaverLok (2) shoulder and SaverLok
collar (3) threads and shoulder with clean
TJC.
3.
Apply grease or lubricant to the SaverLok o-
ring and insert SaverLok into SaverLok
connection. The connection will not lock fully
into place.
4.
Thread SaverLok into connection until o-ring
is fully engaged using one of the following
methods:
•
Slide SaverLok collar over SaverLok and engage threads by hand. Once the SaverLok collar is
hand tight (bottomed out), remove collar.
•
Tap the SaverLok nose with a rubber mallet until the o-ring is fully engaged.
5.
Slide SaverLok collar over SaverLok and hand-tighten the threads (typically 3-4 turns).

Start unit and position carriage so that collar can be clamped in the rear wrenches.
7.
Clamp wrench on collar and tighten SaverLok assembly to a rotation pressure gauge reading between
2000-3000 psi (138-207 bar). This is equivalent to 1500-2500 ft•lb (2034-3390 N•m) of torque.

Immediately loosen the collar and repeat the tighten/loosen process five times to break in the contact
surfaces.
