Unequal engagement adjustment of rod ends (8,9)
and push rod (10) can cause failure of a rod end
(8,9)-to-push rod (10) connection.
a. If this occurs during bench main te nance, the
parts (8,9,10) could snap apart and cause
per son al injury.
b. If this occurs during installed operation, con trol
func tion would be lost.
e. Loosen lower L.H. rod end (9) jam nut (44)
by rotating CW (viewed from above); this
nut (44) is “left-handed”. Back nut (44) to
the root of its threads on push rod (10).
f. Using a suitable tool to prevent lower L.H.
rod end (9) from rotating, rotate push rod
(10) CCW (viewed from above) until up per
end of push rod (10) is fully engaged with
upper R.H. rod end (8). NOTE: If lower L.H.
rod end (9) reaches full en gage ment with
lower push rod (10) end fi rst, remove tool
securing against ro ta tion, and allow lower
L.H. rod end (9) to rotate with push rod
(10). Once upper end of push rod (10) is
fully engaged with upper R.H. rod end (8),
rotate lower L.H. rod end (9) CW (viewed
from above) until it is fully engaged.
g. Provide a temporary air supply with an
inline ad just able airset to the actuator
upper cas ing (1) connection.
h. Reference the name plate (21) attached
to the cover plate (20) that is fas tened to
the arm hous ing (4). De ter mine the bench
set ting from the name plate (21).
i. Pres sur ize the ac tu a tor (AA) to the lower
val ue of the benchset range pres sure
in di cat ed on the name plate (21).
j. While holding low er L.H. rod end (9) out
of way, lift lever arms (5) up as far as pos-
si ble (this will close plug (Ranger (5))/disc
(Pre mier (3.1)).
k. Rotate lower L.H. rod end (9) as required
to orient the holes of the rod end (9) and
the lever arms (5) in the same plane. Swing
low er L.H. rod end (9) be tween the lever
arms (5).
l. Rotate the push rod (10) CW (viewed
from above) lowering the lower L.H. rod
end (9) until it’s hole is centered with the
lever arm (5) holes. Center lever arms (5)
with in arm housing’s (4) transverse axis;
i.e. center over travel stop screw (35).
m. Reinstall the shoulder bolt (40) through
the lever arm (5) and lower L.H. rod end
(9) holes. Finger-tighten lock nut (46) onto
shoul der bolt (40). Using a 1/4" allen key
wrench to secure the head of shoul der
CAUTION
bolt (40), torque wrench-tighten nut (46)
to 15-20 ft-lbs (20-27 N-m).
n. Tighten lower L.H. jam nut (44) down until
locked against lower L.H. rod end (9); nut
(44) is “left-handed”.
o. Add approximately 6 psig (0.4 Barg) to the
actuator’s (AA) lower value of benchset
range. This will extend the actuator stem/
push rod sub-assembly (8, 9, 10, 43, 43,
43, 44, 54) downwards to al low loos en-
ing double jam nuts (43) on top side of
uptravel stop washer (54).
p. Release air pressure down to the lower
value of benchset range.
q. Rotate lower jam nut (43) to raise uptravel
stop wash ers (54) until the gap clearance
between the lower casing (2) and the
top side of the washer (54) is 1/8"±1/16"
(3mm±1.5mm).
r. Repressurize actuator (AA) to level as
indicated in Article 5.o. above. Tighten
the lower of the two upper jam nuts (43)
until it is tight, and secures the uptravel
stop washer (54). Tighten the upper of
the two upper jam nuts (43) down to
secure the double jam nut (43) locking
effect. Retighten lower jam nut (43) on
un der neath side of washer (54).
s. Release all air pressure from actuator
upper casing (1). Repressurize slowly to
confi rm that as the pressure reaches the
lower valve of the benchset range (see
Article 5.i. previous), the actuator stem/
push rod sub-assembly (8, 9, 10, 43, 43,
43, 44, 54) begins to move. If move ment
is prematurely occurring (i.e. move ment
at less than the lower benchset range
