C. Installation of the Actuator Eye-End
(1) Lubricate the washers (3) and (5) and the blocking-cup (11) with Silicone base Grease-General Purpose - - (Material No.03JBA1) or Silicone base Grease-Mechanisms and Seals - - (Material No.03JCA9) .
(2) Lubricate the lockwasher (9) with Non Hardening Jointing Putty-Medium Temp. Area - - (Material No.06LCG9) .
(3) Install the washer (3) on the adjusting nut (4).
(4) Install the washer (3), the adjusting nut (4) and the washer (5) on the eye-end (13).
(5) Install the LVDT core (7):

CAUTION: DO NOT MIX THE CORES/COILS FROM DIFFERENT LDVT UNITS. THEY ARE IN PAIRS.

(a) Install the LVDT core (7) into the adjusting nut (4).
(b) Set the flat on the LVDT core (7) so that you can install the pin (12).
(c) Assemble the blocking-cup (11), the spring (6) and the slotted-cup (10) to the LVDT core (7).
