Use of Molykote type GN metal paste (high pressure lubricant) is necessary for proper
operation of the grips. Instron recommends only this brand and type of high pressure
lubricant. Use of any other lubricant risks damage to the grip components. This damage
would not be covered under warranty.
4. Insert the grip jaws into the grip pocket. See the NOTE above regarding matched grip jaw pairs. Be
sure to insert the jaws properly.
5. Insert appropriate filler plates (shoulders will rest on top of crosshead) into the grip pockets from the
top of the crosshead so that they sit between the sloped sides of the grip pocket and the sloped side
of the grip jaw. See the “Filler plate guidelines (G1-style crossheads only)” on page 45 for
important information on selecting and inserting filler plates.
It is important that the lubricant on the grip jaws, grip pocket and filler plates is always moist and is not
dry, clumped or dirty.
