DESCRIPTION AND OPERATION

1. General
A. The main landing gear is a twin axled lever suspension unit handed left and right for installation. A two
stage shock absorber and an oleo lock jack are included in the assembly. The oleo lock jack actuates a
downlock locking device.
B. Description and operation of the shock absorber is given in Component Maintenance Manual 32-10-66
and the oleo lock jack in Component Maintenance Manual 32-30-72.
2. Description (Refer to Figures 1 to 5)
A. The main landing gear comprises a main fitting sub-assembly, a wheel lever and axle sub-assembly, a
downlock mechanism, electrical harnesses and hydraulic pipes. The main fitting sub-assembly and the
wheel lever and axle sub-assemblies are connected by a wheel lever pin sub-assembly.
B. Main Fitting Sub-assembly (Refer to Figures 1, 2, 3 and 4)
(1) The main fitting sub-assembly consists of a hollow cylindrical forging formed to incorporate a
webbed extension arm at the upper section and a bushed leg extension at the bottom. The top end
of the main fitting sub-assembly cylinder incorporates two bushed lugs which, together with the end
face of the extension arm, house the forward and rear pintle pins respectively and form the pivoting
point of the main landing gear. A bushed transverse hole below the forward pintle pin houses the
retraction jack pin and a bushed lug adjacent to that pin provides the attachment point for the oleo
lock jack.
(2) Two large bushed lugs extending from the main fitting provide the fulcrum point for the direction
crank sub-assembly and the lever sub-assembly. A further two holes integral with the large lugs
carry the lock lever pin which locates the lock lever sub-assembly in place. Two bushed lugs that
extend on the opposite side of the main fitting sub-assembly house the sidestay pin. At the base of
the main fitting sub-assembly the forging forks into two bushed legs which house the wheel lever pin
sub-assembly. The extended leg is formed with four parallel webs bushed for door attachment pins.
(3) The forward and rear pintle pins, the sidestay pin and the lock lever pin each house a sealed grease
sleeve which channels grease from the lubrication fittings of each component to the relevant
bearing surface of each pin and its associated bush. The retraction jack pin houses a grease plug.
The forward pintle pin is a hollow pin closed at one end and locked by a lockplate and keep plate on
final installation. The rear pintle pin is a hollow sleeve and is secured by a pin passing through the
webbed extension, the pin and the grease sleeve sub-assembly. The sidestay pin is a hollow pin
that includes a flange with an attachment lug.
(4) The direction crank sub-assembly comprises a pin with a crank arm and a bush. The pin, with the
bush assembled, is located in the large bushed lugs of the main fitting sub-assembly with a cam ring
assembled to the pin in between the two lugs and secured with a bolt, nut and washer. The crank
arm has two bushed lugs for the shock absorber upper pin. A lever sub-assembly is assembled to
the direction crank sub-assembly and secured by a pin inserted through a lock sleeve sub-assembly
located inside the direction crank pin. The lever sub-assembly includes two bushed lugs for the
direction link sub-assembly attachment pin. A lock lever sub-assembly is located between the large
lugs and comprises a lever with integral forked lugs, a pawl and a pivot pin bore. The lugs are
attached to the oleo lock jack.

C. Wheel Lever and Axle Sub-assembly (Refer to Figures 4 and 5)

(1) The wheel lever sub-assembly is hinged to the main fitting by a wheel lever pin sub-assembly
retained by a nut to which a target is fitted for the actuation of a weight off sensor. The closed end
of the pivot pin terminates in two lugs to which an uplock pin is fitted. A target is also fitted to this
end of the pin for actuation of a weight off sensor. A locking pin, secured by a plate and a nut is
formed with flats on its inner end to locate in a slot in the pivot pin to ensure that the uplock pin is at
the correct angle.
(2) Lugs on the wheel lever provide a housing for the attachment pin to receive the lower end of the
shock absorber. A sealed end cap closes the open end of the attachment pin. Two lubrication
fittings in the end cap, together with two lubrication fittings in the end face of the attachment pin
provide for lubrication of the joint.
(3) Passing through the bushed bore at the lower end of the wheel lever is the axle, retained by a
jacking dome pin secured by a nut. Two lubrication fittings connect through greaseways in the
wheel lever to service the axle. A spacer and wheel nut is fitted to each end of the axle, and its
open ends are fitted with a collar, secured by two bolts, which also retain the wheel nuts.
Immediately behind the axle a brake unit pin fits into a bushed bore.
D. Electrical Harnesses (Refer to Figures 1 and 4)
(1) Three electrical harnesses are clamped to the main fitting sub-assembly and the wheel lever
sub-assembly. On Post SB 146-32-114 installations, the brake cooling fan harness, temperature
sensor and anti-skid harness are replaced by a single brake cooling fan, temperature sensor and
anti-skid harness. At the upper end each harness flying lead terminates at a connector for
installation to the aircraft.
(2) The temperature sensor and anti-skid harness contains a manifold which is bolted to the top of the
wheel lever and axle sub-assembly. On Post SB 146-32-114 installations, the harness enters a
junction box bolted to the top of the wheel lever and axle sub-assembly. Wires from the harness are
routed into the wheel lever and axle sub-assembly through two cable guide sub-assemblies. The
wires terminate at an anti-skid connector inside each end of the axle. Two further branches from the
manifold terminate at brake temperature connectors. The harness branches into two leads above
the manifold which are routed up the main fitting sub-assembly.
(3) The weight off sensor harness is formed into two branches adjacent to the shock absorber upper
attachment pin. Each branch terminates at a weight off sensor and is attached to a switch bracket
bolted on each side of the main fitting sub-assembly (Refer to Figure 4).
(4) On Pre SB 146-32-114 installations, the brake cooling fan harness connects into the manifold on top
of the wheel lever and axle sub-assembly. Two branches are pre-coiled and fit inside the axle,
terminating at a connector at each end.
E. Hydraulic Pipe Sub-assemblies (Refer to Figure 1)
(1) Hydraulic pipe sub-assemblies clamped at intervals to the main fitting sub-assembly and the wheel
lever and axle sub-assembly, convey hydraulic fluid for operation of the normal brake system, the
stand-by brake system and the auto brake system. A flexible hose teed off the auto brake supply
pipe sub-assembly conveys fluid to the oleo lock jack. Flexible hoses, pipe sub-assemblies and
harnesses are protected by a hose guard bolted to the wheel lever and axle sub-assembly.

3. Operation (Refer to Figure 6)

A. Extended and Locked
(1) When the main landing gear unit is in the extended position the oleo lock jack is extended under the
influence of its internal spring with no hydraulic pressure applied.
NOTE : Refer to CMM 32-30-72 for operation of the oleo lock jack.
(2) The lock lever sub-assembly abuts the cam ring preventing the direction crank sub-assembly from
rotating.
NOTE : When the main landing gear unit is installed the direction link sub-assembly is anchored in
a fixed position.
B. Shortened
(1) With hydraulic pressure applied to extend the oleo lock jack, the lock lever sub-assembly is rotated
off the face of the cam ring.
(2) Movement against the fixed direction link sub-assembly pivots the direction crank sub-assembly
thus raising the shock absorber and the wheel lever sub-assembly.
C. Compression and Extension
(1) A compressive load applied to the axle sub-assembly pivots the wheel lever and axle sub-assembly
compressing the shock absorber to absorb the load. With the load removed the shock absorber
returns the wheel lever and axle sub-assembly to the extended position.
NOTE : Refer to CMM 32-10-66 for operation of the shock absorber.

2. Test Conditions
WARNING : DO NOT GET HYDRAULIC FLUID ON YOUR SKIN OR IN YOUR EYES. DO NOT BREATHE
THE FUMES. ONLY USE IN A LOCATION THAT HAS A CONTINUOUS FLOW OF CLEAN
AIR. HYDRAULIC FLUID IS POISONOUS AND DANGEROUS.
A. General

(1) The hydraulic test rig must be capable of supplying pressure at 4500 lbf/in2 (31 MPa) on a hand
pump.
(2) The temperature of the test fluid must be between 68 °F and 140 °F (20 °C and 40 °C).
(3) Fluid cleanliness standards must be in accordance with M-DLPS910-1.
(4) During all tests the unit and the test circuit must be hydraulically full.
(5) Examine the unit for damage before you start the tests.
3. Procedure
A. Electrical Tests (Refer to Figure 101 to 103 and IPL Figure 7)
(1) Pre SB 146-32-114, carry out a continuity check on all circuits of the brake cooling fan harness
(7-250), and the temperature sensor and anti skid harness (7-270). Reference should be made to
Ultra Electronics Component Maintenance Manual 32-00-10.
(2) Post SB 146-32-114, carry out a continuity check on all circuits of weight off sensor harness (7-230),
the brake cooling fan harness (7-250), the temperature sensor and anti-skid harness (7-270) or the
brake cooling fan and anti-skid/brake temperature harness (7-250C) (Post SB 146-32-114).
Reference should be made to Ultra Electronics Component Maintenance Manual 32-00-10 and
32-00-11 respectively.
CAUTION : ONLY ONE LEAD IS TO BE PLUGGED INTO THE LAMP BOX AT ANY ONE TIME.
(3) With the landing gear mounted in Assembly Stand 460004936, connect the Lamp Box 460004859
to a 24 VDC supply and connect the weight off sensor harness (7-230) into the socket marked MAIN
U/C.
(4) On the Lamp Box 460004859 set the selector switch to SENSOR 1, switch ON the 24 VDC supply,
the lamp must come on. Set the selector switch to SENSOR 2, the lamp must remain on. Return
the selector switch to SENSOR 1.
NOTE : A lamp ON indication at both selector switch settings determines that continuity exists in
the weight off sensor harness (7-230). To determine which weight off sensor is active,
when the selector switch is set to SENSOR 1, proceed as follows. Insert a thin strip of
non-ferrous material (aluminium alloy is recommended) between each target and weight
off sensor in turn. Note which lamp goes out, this will be the active sensor.
(5) Using Blanks 460004446/1, blank off the pipe sub-assemblies (11-80 and 11-100). Connect the
Test Adapter 460004941/3 to the elbow (10-300) and connect the hydraulic test rig hand pump sup
ply to the Test Adapter 460004941/3. Apply pressure to operate the oleo lock jack (2-120) and lift
the oleo lock lever sub-assembly (16-20) away from the cam ring (16-400).
(6) Locate the hydraulic jack under the jacking dome of the wheel lever and axle sub-assembly (13-20)
and extend it between 0.5 and 1.0 in (12,7 and 25,4 mm). The lamp must go out. If the lamp does
not go out, adjust the shim (7-200) to obtain this condition and re-assemble in accordance with
ASSEMBLY.

ILLUSTRATED PARTS LIST
1. Introduction
A. General
(1) This parts list illustrates and identifies each part of the component in this CMM. Use it to
identify parts and to help with provisioning.
(2) The Illustrated Parts List contains:
(a) a Numerical Index (where applicable)
(b) a Detailed Parts List
(c) all necessary data for the procurement of parts.
B. Numerical Index (where applicable)
(1) The Numerical Index is to help you find part numbers in the Detailed Parts List.
(2) Deleted or superseded part numbers have these identifications:
(a) Deleted - (D)
(b) Superseded - (S)
(3) The Total Required column (TTL REQ.) shows the total necessary each time the part
number is shown in the Detailed Parts List.
C. Detailed Parts List
(1) In general part numbers are in the DISASSEMBLY sequence. The parts are indented to
show that they are related to the next higher assembly (NHA).
(2) The Effectivity Code (EFF. CODE) agrees with that of the next higher assembly. The
effectivity code also shows if subassemblies and details are applicable to their next
higher assembly or sub-assembly. When an item is applicable to all units the Effectivity
Code column will be empty. The effectivity code usage is specific to the IPL figure to
which it applies.
(3) The quantity in the Units per Assembly column is the quantity necessary for the next
higher assembly. AR in the Units per Assembly column shows that the quantity of parts
to be used is as required. RF in the Units per Assembly column shows that the part is for
reference only.
(4) The Part Numbers that are shown (NP) in the Detailed Parts List are non-procurable
items. Unless the part has been superseded the next higher assembly must be installed.
