RE-CIRCULATING COOLING CIRCUIT FOR
MODELS MCA, MCS, MAA, MAS, MLA and
MLS (Figure 3)
This type of installation may be required when
ambient temperatures and/or cycle rates cause
0 the shock absorber to heat up beyond 150 F
0 (65 C).
Use high pressure 1,000 psi (69 bar) check valves
with a low cracking pressure of 5 psi (0.34 bar).
If a filter is to be used in this circuit, a 30 to 40
micron filter element with a 5 psi (0.34 bar) by-pass
is recommended. Consult factory for assistance.

Side Port Torque Notice APPLYING APPROPRIATE TORQUE
WITHOUT CALIBRATED TOOLING
The following procedure may be utilized if
calibrated tooling is not available to torque
lock nut.
Note: it is assumed that all necessary
installation instructions have been followed
prior to this procedure.
1. After positioning the shock properly in relation
to the accessory (i.e. flange, collar, etc.) or
mounting surface, with the proper adhesive (if
applicable), finger tighten the lock nut against
the accessory or mounting surface until it can no
longer be turned.
2. Using appropriate equipment, tighten the
lock nut until it rotates 1/8 to 1/4 of a full rotation
(45 to 90 degrees) from the finger tight position.
ACE has determined that a lock nut secured in
this manner meets the torque specifications
listed in the chart above.
