If inside calipers are not available, or clearance prevents their use, screw rod end into piston until distance between centerline of rod end bolt and point marked on actuator housing during rod end removal is exactly as that recorded in step 3.L. Ensure that switch assembly turns with rod end and seats correctly in piston.

C. Install switch by installing spring, threading switch leads through holes inside of rod end and sliding switch into position in rod end.
NOTE: Ensure that flats on switch align with flats in rod end. This step does not apply if replacement switch and rod end come preassembled.
D. If installing switch, part No. 65-44873-10, connect switch leads to connector plug as follows (Detail B):
(1)
Connect ground wire to switch lead.
(a)
Strip outer jacket from switch lead to within 4.5 inches of rod end. Cut shielding at sufficient distance from end of jacket to allow folding the shielding over sleeve.
(b)
Slide inner sleeve over shielding and fold shielding back over inner sleeve.
(c)
Strip insulation from end of ground wire to expose 1/2 inch of conductor. Double conductor back on itself making an exposed end of 0.25-inch long.
(d)
Lay exposed conductor of ground wire on exposed shielding of switch lead. Ground wire is to point toward connector plug.
(e)
Position outer sleeve over ground wire connection and center over inner sleeve. Hexagonal swage outer sleeve to make a secure connection.
(2)
Cut switch lead and ground wire as required to provide overall length of 7.00 to 8.00 inches from rod end to outer end of connector plug, when connected.
(3)
Using connector pin insertion tool, connect switch lead to pin 2 of connector plug and ground wire to pin 1.
(4)
Screw rod end into piston until distance between centerlines of actuator support fitting bolt and rod end bolt is 12.69 to 12.71 inches. Use inside calipers to measure distance. Ensure that switch assembly turns with rod end and seats correctly in piston.
(5)
If inside calipers are not available, or clearance prevents their use, screw rod end into piston until distance between centerline of rod end bolt and point marked on actuator housing during rod end removal is exactly as that recorded in step 3.L. Ensure that switch assembly turns with rod end and seats correctly in piston.
(6)
Tighten locknut to 220-300 pound-inches. Lockwire nut and locking key.

E. On actuators using switch, part No. 65-44873 ALL EXCEPT part No. 65-44873-10, connect switch lead to connector plug as follows: (See Detail B).
(1)
On rod end assemblies with wire rope hole, position wire rope alongside switch lead wire and slide on heat shrink tubing, RT-876-1/8. Do not shrink.
(2)
Connect ground wire to switch lead.
(a)
Strip outer jacket from switch lead to within 4.5 inches of rod end. Cut shielding at sufficient distance from end of jacket to allow folding the shielding over sleeve.
(b)
Slide inner sleeve over shielding and fold shielding back over inner sleeve.
(c)
Strip insulation from end of ground wire to expose 1/2 inch of conductor. Double conductor back on itself making an exposed end of 0.25-inch long.
