Copyright © 2014 by Embraer S.A. All rights reserved.1. Re-torque the castle nut PN PE22072L14 of the LH/RH lower link fitting outboard as follows: (a) Remove and discard cotter pin PN MS24665-374 (1 position). Refer to Detail B

. (b) Re-torque the castle nut PN PE22072L14 (1 position) as shown in Detail B and do the steps that follows: NOTE: Make sure that the shear pin does not turn when you apply the torque. If necessary, safety the other side of the shear pin with a proper wrench to do not permit it to turn. 1 Loosen the castle nut PN PE22072L14 (1 position). 2 Turn the castle nut PN PE22072L14 and measure the drag torque with a torque wrench. 3 Make sure that the drag torque is between 7.91 - 67.79 N.m (70 - 600 lb.in). NOTE: If the castle nut PN PE22072L14 is not in the correct range, replace it with new one with the same part number. 4 Add the drag torque value measured in 1.(b)2 Figure 2 to the standard torque of 112.98 - 225.97 N.m (1000 - 2000 lb.in) to get the final torque. 5 Apply the final torque to the castle nut PN PE22072L14 with a torque wrench.Refer to AMM TASK 20-10-01-910-801-A/200 - Bolt Torque Data - Maintenance Practices. (c) Install the cotter pin PN MS24665-374 (1 position). Refer to Detail B

. (d) Clean up the reworked area and apply Corrosion Inhibiting Compound, Type III (MEP 10-063) ARDROX AV-15 . Refer to Detail B
