As Needed
To install:
1. Inspect SaverLok
®
connection (1) for damage.
Coat threads with clean TJC.
2. Coat SaverLok shoulder (2) and SaverLok
collar (3) threads and shoulder with clean TJC.
3. Apply grease or lubricant to the SaverLok o-ring
and insert SaverLok body into SaverLok
connection. The connection will not lock fully
into place.
4. Thread SaverLok body into connection until o-
ring is fully engaged using one of the following
methods:
• Slide SaverLok collar over SaverLok body
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. Position SaverLok body by hand for proper engagement of pins and grooves.
6. Slide SaverLok collar over SaverLok body and hand-tighten the threads (typically 3-4 turns).
7. Start unit and position carriage so that collar can be clamped in the rear wrenches.
8. Clamp wrench on collar and tighten SaverLok assembly to a rotation pressure gauge reading between
4500-5000 psi (310-345 bar). This is equivalent to 4500-5000 ft•lb (6101-6779 N•m) of torque.
9. Immediately loosen the collar and repeat the tighten/loosen process five times to break in the contact
surfaces.
10. Tighten SaverLok assembly to a rotation pressure gauge reading between 4350-5800 psi (300-400
bar) to finish the installation.
