R A. Installation of the Electrical Connector (1074GK-A)
R (Ref. Fig. 401/TASK 29-11-17-991-902, 402/TASK 29-11-17-991-300)
R (1) Do these steps to install the electrical connector.
R
R PRE SB RA32029-13
R
R (a) Remove the protective covers from the hydraulic tube (25), the
R electrical connector 1074GK-A and the pressure switch (15).
R (b) Clean the bonding surfaces of the clamp (10) and the pressure
R switch (15) with a clean cloth made moist with CLEANING AGENTS
R (Material No. 11-004).
R NOTE : There must be a good electrical bond between the pressure____
R switch (15), the clamp (10) and the channel bracket (20)
R ground stud.
R (c) Wipe the bonding surfaces with a clean cloth before the solvent
R becomes dry.
R (d) Put the bonding clamp (45) on the switch (15).
R (e) Attach the bonding jumper (50) to the clamp (45) with the bolt
R (5), the washers (35), (40) and the nut (30).
R (f) TORQUE the nut (30) to between 20 and 25 lbf.in (0.22 and 0.28
R m.daN).
R (g) Do an electrical resistance check as follows:
R 1_ Put one lead of the ohmmeter on the pressure switch (15).
R 2_ Put the other lead of the ohmmeter on the bonding clamp (45).
R 3_ The resistance measured between the ohmmeter leads must be
R 0.0025 ohm or less.
R 4_ Put one lead of the ohmmeter on the pressure switch (15).
R 5_ Put the other lead of the ohmmeter on the ground stud on the
R channel bracket (20).
R 6_ The resistance measured between the ohmmeter leads must be
R 0.0025 ohm or less.
R 7_ If the resistance is more than 0.0025 ohm, remove the bonding
R clamp (45) and clean the bonding surfaces again.
R 8_ Do this procedure until the resistance indication is in the
R correct range.
R (h) Install the pressure switch (15) on the channel bracket (20) with
R the clamp (10) and the bolts (5).
R (i) TORQUE the bolts (5) to between 20 and 25 lbf.in (0.22 and 0.28
R m.daN).
R (j) Connect the hydraulic tube (25) to the pressure switch (15).
R NOTE : Use a second wrench to hold the pressure switch (15) when____
R you TORQUE the coupling nut on the tube (25).
R (k) TORQUE the coupling nut on the tube (25) to between 620 and 680
R lbf.in (7.00 and 7.68 m.daN).
R (l) Install the electrical connector 1074GK-A on the pressure switch
R (15) and tighten it with your hand plus one-eighth of a turn.
R (2) Do these steps to install the electrical connector.

R POST SB RA32029-13
R
R (a) Remove the protective covers from the hydraulic tube (5), the
R electrical connector 1074GK-A and the pressure switch (30).
R (b) Install the pressure switch (30) and the bonding jumper (10), on
R the channel bracket (40) with the master electrical keyway facing
R forward. Use the clamp (25), the bolts (15) and the washers (20).
R NOTE : Make sure the bonding jumper (10) is installed under the____
R clamp.
R (c) TORQUE the nuts (15) to between 20 and 25 lbf.in (0.22 and 0.28
R m.daN).
R (d) If required, attach the other end of the bonding jumper (10) to
R the ground stud 9951DC on the ground plate with the existing
