10. Feed the brake line through the left hole in the forward main bulkhead.
11. Feed the left MLG subassembly through the opening in the bottom of the right Seawings™ and
into position between the main bulkheads. This assembly should be complete with leg, boot, trun-
nion, and pushrod.
12. Ensure that the ICA007426 MLG trunnion pivot bushings are in good condition and install one in
each of the sleeve bearings in the main bulkheads at the trunnion pivot.
13. Coat two AN10C20S bolts with Tef-Gel
®
and, supporting the weight of the left gear leg, install
them with their nuts and washers, through the ICA007426 bushings and into the left MLG trun-
nion, securing it to the bulkhead pivot points. The bolt heads should face away from the trunnion.
Use 15/16 wrenches to torque each fastener to 900±100 in-lb
f
.
14. Supporting the weight of the left gear leg, align the left MLG pushrod to the MLG bellcrank and
install the wrist pin, sliding it in from the back forward.
15. Install the S73HW2-100-100 retaining ring into the groove on the wrist pin.
16. Connect the MLG actuator electrical connector to the aircraft harness.
17. Route the left and right brake lines forward to the parking brake valve. Reinstall any cable ties
that were removed and install the MS35489-35 rubber grommets at the forward main bulkhead
interface.
18. Remove any caps from the brake lines and parking valve then, using a 7/16 wrench to hold the
aft union fittings at the valve and a 1/2 wrench to connect the left and right brake lines to the aft
side of the valve, torque each B-nut to 30-40 in-lb
f
.
19. Check and adjust the MLG actuator stops using the rigging procedure. (See “Inspect Flap
Rigging” on page 9-65.) The boots are not yet bonded, so ensure that they do not interfere with
gear operation.
20. Once the landing gear is operating properly, bond the MLG boots in place. (See “Main Landing
Gear (MLG) Boot Installation” on page 14-42.)
21. Install the seat backs and baggage floors. (See “Seat Back Installation” on page 3-51.)(See
“Baggage Floor Installation” on page 3-42.)
22. Check the MLG bay for tools or anything else amiss, then install the aft bulkhead baggage panel.
(See “Baggage Sidewall Panel Installation” on page 3-45.)
23. Lower the aircraft off of the jacks.
VERIFICATION METHOD:
The main landing gear actuator should fall within the range specified in the rigging procedure. (See
“Inspect Flap Rigging” on page 9-65.)
