Series 322 Load Unit Maintenance

Preloader collar mount

only

The following procedure applies only to force transducers that are mounted

to the crosshead using a preload collar.

Loosen the six jack bolts or setscrews in 1/4 turn steps to remove most of the

tension on the preloader collar, following a standard crisscross torque

sequence.

• If your preloader collar has jackbolts, remove and lubricate them one at

a time. Lubricate the washer underneath the jackbolt. After you

reinstall the jackbolt, tighten it enough to keep the force transducer

pulled firmly against the crosshead.

• If your preloader collar has captive setscrews, unscrew them one at a

time. Lubricate the washer underneath the setscrew. Then retighten the

setscrew just enough to keep the force transducer pulled firmly against

the crosshead.
