3610J and 3620J Positioners
face and the lever face and to
determine the proper tightening torque
for the lever clamping bolt.
10. Connect the turnbuckle and the lever arm.
11. Replace the actuator cover and the travel
indicator in the positions that were marked in step 1.
CAUTION
To avoid parts damage, do not
completely stroke the actuator while
the actuator cover is removed.
WARNING
To avoid personal injury from moving
parts, keep fingers and tools clear
while stroking the actuator with the
cover removed.
To aid cover alignment on 1051 and
1052 actuators, use a regulated air
source to move the actuator slightly
away from its upper travel stop. If hole
alignment is still not possible,
temporarily loosen the cap screws that
secure the housing to the mounting
yoke, and shift the housing slightly.
Mounting 3611JP and 3621JP
Positioners on 585 and 585R Size 100
Actuators
Refer to figure 4 for part locations. Refer to figure 29
for key number locations unless otherwise indicated.
1. Refer to the appropriate actuator instruction
manual. Loosen the four screws, and remove the
front yoke cover plate from the actuator.
2. Stroke the actuator from the top stop to the
bottom stop, and record the travel distance.
3. Loosen the four captive cover screws and
remove the positioner cover (key 41, figure 28).
4. Refer to the appropriate actuator instruction
manual. Loosen the four screws, and remove the
actuator blanking plate.

Note
5. Attach the positioner adapter (key 113) to the
actuator with four socket head screws (key 54).
6. Disconnect the positioner range spring (key 150,
figure 25) from the range spring hanger (key 130,
figure 25).
7. Attach the roller (key 175) and washers (key 184)
to the adjuster assembly (key 174) and secure with
the retaining ring (key 172).
8. Apply pressure to the actuator piston and move
the actuator to approximately the mid-travel position.
9. Install the positioner on the actuator so the
feedback lever assembly (key 170) is under the stem
bracket and secure the positioner to the adapter
(key 113) with the four socket head screws (key 54).
10. With the actuator still at mid-travel and the top
edge of the feedback lever assembly perpendicular
to the actuator stem, install the adjuster
assembly/roller in the appropriate stem bracket slot
with the button head screw (key 173) so the roller is
centered over the correct actuator travel marked on
the feedback lever assembly (key 170) as shown in
figure 4.
11. Tighten the button head screw (key 173) and
replace the range spring (key 150, figure 25).
12. For size 100 actuators with greater than a 51
mm (2-inch) travel, install the feedback lever spring
(key 185).
13. Replace the positioner cover.
14. Replace the front actuator cover plate.
15. Discard the actuator blanking plate and the four
screws.
Mounting 3611JP and 3621JP
Positioners on 585C and 585CR Size 25
and 50 Actuators
The 3611JP pneumatic positioner and the 3621JP
electro-pneumatic positioner can be mounted on
either a 585C or 585CR piston actuator. A positioner
adaptor (key 113) attaches to the back of the
positioner and serves as the interface to the
mounting bracket (key 194). Refer to the 585C and
585CR actuators instruction manual (part number
D102087X012) for additional information on the
actuator.
