(e) ENGINES PRE-PW-SB 72-498;
Attach the bearing stops (27) to the support bracket with the
bolts (25) and nuts (24).
NOTE: If the clearance between the bolt hole in the bearing____
stop (27) and bolt (25) is not satisfactory for the
correct installation of the bolt, refer to PW SB PW4ENG
75-38 for bearing stop repair.
(f) ENGINES POST-PW-SB 72-498;
Attach the bearing stops (27) to the support bracket with the
bolts (25), washers (24A) and nuts (24).
NOTE: If the clearance between the bolt hole in the bearing____
stop (27) and bolt (25) is not satisfactory for the
correct installation of the bolt, refer to PW SB PW4ENG
75-38 for bearing stop repair.
1) Tighten the nuts to 36-40 pound-inches (4.1-4.5
newton-meters).
2) Install the cotter pins (23).
(g) Lubricate the threads of the shoulder bolt (4) with engine oil.
(h) Attach the rod end bearing (5) to the bellcrank lever with the
shoulder bolt (4), washer (3), and nut (1).
1) Tighten the nut (1) with your hand.
(i) Lubricate the threads of the bolt (19) with engine oil.
(j) Attach the ground cable (20) to the actuator (7) with the bolt
(19).

CAUTION: USE THE CORRECT ASSEMBLY PROCEDURE, AND TOOLS, FOR THE
_______ HARNESS CONNECTOR INSTALLATION (AMM 70-24-05/201). IF YOU USE THE INCORRECT ASSEMBLY PROCEDURE, OR TOOLS, A DAMAGED OR LOOSE CONNECTOR CAN OCCUR. A LOOSE CONNECTOR PERMITS VIBRATION, WHICH CAUSES THE CONTACTS TO WEAR AND DECREASES THE LIGHTNING PROTECTION.
(l) Connect the electrical connector (17) to the lower receptacle, and the electrical connector (18) to the top receptacle on the actuator (7) (AMM 70-24-05/201).
