ADJUSTMENT FOR (A) 2” & 3” LARGE BORE SERIES
(Figure 5)
Proper adjustment is important for the efficient
operation of the ACE adjustable shock absorber. All
units are preset at the factory at 5. After installation of
the shock absorber, cycle the machine a number of times.
Turn the hex socket adjuster, on the bottom of the shock
absorber, against the scale marked 0 to 9 until optimum
deceleration is achieved (i.e. smooth deceleration
throughout the stroke). If hard impact is experienced
at the start of the stroke, turn adjuster toward 9. If
hard set-down is experienced at the end of stroke,
turn adjuster toward 0. If the final setting is less than 2
or greater than 8, a different shock absorber should be
utilized.
Note: flanges, side-foot mount and clevis mount assemblies are available from
ACE Controls directly or through distributors. See the ACE main catalog or
visit the ACE web site for stocking distributor locations.

CAUTION NOTE: CLEVIS MOUNT INSTALLATION

adjustment of the shock, apply thread lock adhesive
to the clevis flange mounting bolts and torque to
110-121 ft-lbs (150-165 Nm).

CLEVIS MOUNT INSTALLATION (Figure 4)
Fasten the rear clevis and the rod clevis to the mating
clevis members of the equipment. Make sure the
shock absorber is using the full stroke minus
.09 inch (2.3 mm) so that it does not bottom out.
Assure that the equipment cannot pull the rod out any
farther than the shock absorber strike will allow.
