3.
Using the 5/16” Allen wrench, remove the five socket head cap screws and
lock washers that mount the EM35 actuator to the adapter housing. Remove
the EM35 actuator from the assembly.
4.
Before installing the new EM35 actuator, properly orient the unit so the two
lining pins for the actuator match up with the corresponding holes in the
adapter housing. If necessary, rotate the shaft of the EM35 motor by hand to
properly orient the splines up with those of the coupling assembly.
When everything is in position, first slip the actuator shaft into the coupling
assembly, then line up the pins of the actuator with the adjacent holes in the
adapter housing. The actuator should mate up without any binding or use of
significant force.
5.
Once the actuator is in proper position, re-install the five socket head cap
screws and lock washers removed in step 3. Torque the bolts to 33.2 N
m
(24.5 lb-ft).
6.
Using the 3/16” long ball hex driver and torque wrench, tighten the socket
head cap screw on the coupling at the EM35 output shaft. Torque to 9.3
N
m (82 lb-in).
7.
Reconnect field wiring to EM35 actuator terminal blocks.
8.
Perform valve-stroking procedure, verifying the valve can be stroked from
the minimum to maximum stop.
