Installing Accessories with Spiral Washers
The procedure requires two spanner wrenches and assumes that you are familiar
with all operating aspects of your system.
1. Ensure that system hydraulic pressure has been reduced to zero before
proceeding. To do this, turn off the hydraulic power unit and exercise the
actuator until it stops moving.
2. Clean the connector studs and the internal threads of the force train
element(s). Inspect the thread mating surfaces for signs of contamination or
corrosion. All damaged threads should be repaired or the component
replaced.
3. Apply a thin layer of Molykote G paste, or equivalent, to all thread mating
surfaces.
4. When installing a load cell, place a small piece of compliant material inside
the load cell to keep the stud from contacting the bottom of the hole.
5. Slowly turn the connector stud into an element of the force train (for
example, the actuator rod). The connector stud should turn freely. If any
resistance is encountered, disassemble and correct the problem before
proceeding.
