(1) Lubrication of the Mechanical Control Chain

CAUTION: TO PREVENT MALFUNCTION OF THE THS ACTUATORMOVEMENT:

-MAKE SURE THAT THE CABLE IS IN PROPER POSITIONAND CORRECTLY

-INSTALLED.

-MAKE SURE THAT THE THSA OPERATES OVER THE FULLRANGE BY USING

-THE ELECTRICAL TRIM (ZERO - FULL NOSE-UP - FULLNOSE-DOWN

-ZERO).

(a) Verify the proper position of the cable beforeclosing the cover assembly.

-Make sure that the cable is correctly installed.

-The cable chain assembly must run inside the U-Form of the guide blocks.

(b) Verify that the THS operates over the full rangeby using the electrical trim (ZERO - FULL NOSE-UP- FULL NOSE-DOWN - ZERO) after the cover assemblyhas been closed (Ref. 27-41-00, P. Block 501) .

(2) Lubrication of the THS Actuator Ball Screw Nut

CAUTION: DO NOT MIX LITHIUM-COMPLEX THICKENED GREASEWITH CLAY-THICKENEDGREASE. IF YOU MIX THESE GREASES, YOU CANCAUSE DAMAGE TO THEBALL NUT OF THE THS ACTUATOR.

(a) Make sure that the temperature of the ball screwnut is above 1 °C (33.80 °F).

(b) Clean the vent hole area, the grease nipple andthe THS-actuator ball screw-nut with a clean lint-free cloth (Material No. 19-003).

(c) Use a non-metallic device and make sure that thevent hole is clear.

(d) Put a container in position below the vent hole.

(e) Use a grease gun assembly and apply the new COMMONGREASE (Material No. 04-004) through the greasenipple of the THS-actuator ball screwnut until thenew grease comes out through the nut vent hole.It is normal that some grease comes out throughthe upper/lower nut seal.

(f) Use a grease gun assembly and apply again the newCOMMON GREASE (Material No. 04-004) through thegrease nipple of the THS-actuator ball screw-nut


Page 2 of 31JUN 01/2011

until 150 cm3(9.15 in.3) of the new grease comesout through the nut vent hole.

(g) Remove the unwanted grease from the grease nippleand the top and bottom of the nut with a cleanlint-free cloth (Material No. 19-003).

(h) Remove the container.

(j) Operate the THS to the 14° UP stop position andthen back to the neutral position (Ref. 27-41-00,P. Block 501) .

(k) Clean the THS-actuator ball screw-nut with a cleanlint-free cloth (Material No. 19-003).

(l) Put a container in position below the vent hole.

(m) Use a grease gun assembly and apply the new COMMONGREASE (Material) No. 04-004) through the greasenipple of the THS-actuator ball screwnut until thenew grease comes out through the nut vent holecontinuously.

(n) Use a grease gun assembly and apply again the newCOMMON GREASE (Material No. 04-004) through thegrease nipple of the THS-actuator ball screw-nut

until 150cm3(9.15 in.3) of the new grease comesout through the nut vent hole.

(p) Clean the vent hole area, the grease nipple andthe THS-actuator ball screw-nut with a clean lint-free cloth (Material No. 19-003).

(q) Make sure that the ball in the grease nipple hasclosed correctly after lubrication.

(r) Remove the container.

B. Flaps

CAUTION: TO PREVENT DAMAGE OR DISPLACEMENT OF THE SCREWJACKBALL SCREW NUTSEALS, USE A HANDPUMP GREASE GUN TO GREASE THE BALLSCREW NUTS.IF A HANDPUMP IS NOT AVAILABLE, USE GREASINGEQUIPMENT WITH APRESSURE OF NOT MORE THAN 3 bar (43.5 psi).

CAUTION: DO NOT MIX THE LITHIUM SOAP THICKENED GREASE(04-024) WITH GREASEQUALIFIED TO MIL-G-23827 (04-004), MIL-PRF-23827(04-004), MIL-G-81322
