INTRODUCTION

This manual is written according to Air Transport Association Specification No. 100 for the overhaul
and/or maintenance of the Meggitt Aircraft Braking Systems (MABS) (MABS® is the registered
trademark of Meggitt Aircraft Braking Systems) assembly(ies) included. THIS MANUAL IS
APPLICABLE ONLY FOR THE OVERHAUL OF THE INCLUDED MABS PRODUCT(S) WITH
ONLY MABS PRODUCED OR APPROVED PARTS AND APPROVED PROCEDURES. THE USE
OF UNAPPROVED PARTS OR THE OMISSION OR ALTERATION OF APPROVED
PROCEDURES NEGATES THE VALIDITY OF THIS MANUAL.

The person or facility that uses unapproved procedures or omits recommended procedures to do
an overhaul or maintenance to MABS products may not rely on this manual, must do so at their
own risk and must assume product liability. All torque values and specific limits apply only to MABS
approved parts/products and must be obeyed. Any alternative procedures, limits, or materials (if
consented to in writing by MABS) must not decrease the performance of the assembly.

The Illustrated Parts List of this manual lists and illustrates only the approved parts required to do
maintenance to the assemblies in this manual. The use of unapproved parts in these assemblies
may change the product's performance capability and will nullify the product warranty. The person
or facility that puts unapproved parts in the assemblies may not utilize this manual, must do so at
their own risk and must assume product liability.

All dimensions and other values are in English units followed by the SI (International System) units.
Illustration dimensions are in inches with millimeter conversions in parentheses. Dimensions of
standard tools or parts are in English units where there are no equivalent metric tools or parts.
Illustrations are for reference only and are not to scale.

Meggitt Aircraft Braking Systems represents that the information contained in this manual is valid
only for use with MABS approved parts and procedures and was current at the time of publication
and verified by comparison to engineering documentation.

The user should make sure that this is the most recent publication before overhaul or maintenance
is performed. A dealer, distributor or Customer Support Department can tell the user if this is the
most recent manual. You may make direct inquires to the Distributor Representative-Marketing,
Meggitt Aircraft Braking Systems, Holbrook Lane, Coventry – CV6 4AA, United Kingdom or to the
Technical Publication Department on e-mail at pubs-support@meggitt.com.

If this manual and the aircraft maintenance manual do not agree on the aircraft interface
connections, use the aircraft maintenance manual. This manual may give component functions that
may or may not be used when installed on the aircraft.

(2) Ten bolts (in an outer pitch circle) from the sleeved-side half hub
and ten nuts (on the bushed-side half hub) attach the two half hubs
together. A sealing ring installed in the machined groove of the
sleeved-side half hub makes a pneumatic seal between the half hubs.

(3) A splined sleeve is installed in the sleeved-side half hub and a

bush is installed in the bushed-side half hub. The bush becomes a
stepped bore for the splined sleeve when the two half hubs are
installed together. A minimum clearance fit lets the splined sleeve
into the bush.

(4) Six bolts (in an inner pitch circle) from the bushed-side half hub
and six nuts (on the sleeved-side half hub) attach:
- A split ring around the splined sleeve (bushed-side)
- A location plate on the flange of the splined sleeve
(sleeved-side half hub).

(5) An inflation valve assembly is installed from the sleeved-side half

hub and a nut (on the bushed-side half hub) attaches it in position.

B. Identification

(1) Each wheel has a part number, Mod. state and serial number. Each
half hub also has a part number, issue number and serial number.
Each tire change can be recorded on the tire change pad of the hub.

(2) When a wheel is assembled with a replacement half hub, the

identification data (on the replaced half hub) must be copied to the
replacement half hub (Ref. Assembly, para 2.E.).

(3) Maintenance records are kept for each nose wheel. Records include
data and dates related to modifications or replacement of half hubs
and wheel assembly.

(4) When a nut (70 or 120) can be unserviceable (Ref. para (3)), do
steps (1) thru (3) again. This time use a bolt which is known to
be serviceable. If the nut again checks to be unserviceable (Ref.
para (3)), then reject the nut. If step (3) is completed
satisfactorily this time, then the nut is serviceable, but the bolt
used first (Ref. para (1)) is unserviceable.

E. Minimum Breakaway Torque Test

NOTE: Do this test if you think that the minimum breakaway torque check
was not satisfactory.

(1) Make sure that the nut (70 or 120) and a known serviceable bolt (90
or 140/310) are clean and free from grease (Ref. Cleaning).

(2) Use the torque spanner (Tool No. 19) and adapter (Tool No. 20 or
21) to install the nut (70 or 120). Make sure that two threads of
the serviceable bolt (90 or 140/310) go through the locking device
of the nut (70 or 120).

(3) Use the torque spanner (Tool No. 19) and adapter (Tool No. 20 or
21) to measure the torque necessary to remove the nut (70 or 120)
one full thread pitch. Replace a nut (70 or 120) that has a low
minimum breakaway torque value. The minimum breakaway torque value
must be more than 6.5 lbf in. (0,73 Nm).

F. All Other Parts

(1) Examine the split ring (110) for damage and corrosion. Reject an
unserviceable part.

(2) Examine the location plate (80) for damage and corrosion. Reject
an unserviceable part.

(3) Examine the inflation valve components (30, 40 and 50) for damage
and corrosion. Threads must be in good condition. Reject
unserviceable parts.

G. Wheel Eccentricity And Buckle Check

NOTE: Do this check when the wheel has had some type of heavy landing
(same as landing with a deflated tire).

(3) Immersion in solvent based paint removers for long periods can decrease the
fatigue resistance of a metal half hub and thus, immersion time should be kept to a
minimum.

(4) Blasting a surface for long periods can cause some damage to any surface
treatments, thus blasting times must be kept to a minimum.

C. General Instructions

(1) Complete your selection of paint removal procedure to cause minimum damage to
the half hub.

(2) Meggitt Aircraft Braking Systems do not give approval to procedures that use
chemicals to fully remove paint protection from an aluminium alloy component.

CAUTION: SOLVENT TYPE PAINT REMOVERS THAT IS TOO COARSE WILL

DECREASE THE FATIGUE STRENGTH OF THE HALF HUB AND WILL
REMOVE THE PRE-PAINT CONVERSION TREATMENT.

CAUTION: ABRASIVE BLAST MATERIAL (PLASTIC BEAD AND PEACHSTONE)

MUST BE FREE OF CONTAMINATION AND PARTICLES THAT CAN
CAUSE ELECTROLYTIC ACTION. AIR OCEAN MAROC

(3) Make sure that all threads and other areas where paint removal is not necessary
have masking protection (or are sealed with a plug).

(4) Limit the time of paint removal to the minimum necessary.

(5) Clean the half hub (Ref. Cleaning).

3. Paint Removal Procedures

A. Plastic Bead Blast

WARNING: OBEY THE INSTRUCTIONS SPECIFIED BY THE MAKER OF THE BLAST

EQUIPMENT AND PLASTIC BEAD MATERIAL THAT YOU USE. THE USE
OF BLAST EQUIPMENT CAN BE DANGEROUS.

CAUTION: TO DO BEAD BLAST FOR TOO MUCH TIME (IN ONE AREA) CAN
DAMAGE THE SURFACE TREATMENT AND THEN THE BARE METAL.

(1) The plastic media must meet the requirements of MIL-P-85891 (Type I or II) and
have a maximum hardness of 3.5 MOH or 62 Barcol.

(2) The plastic media must have a size of US screen 20 to 40 mesh

(0.033 to 0.017 in. or 841 to 400 m).

(3) Blasting parameters are dependent on the hardness of the plastic media used for
paint removal. Plastic bead blast as per para (a) or (b) described below:

(a) If the plastic media is MIL-P-85891 Type I with 34 - 42 Barcol hardness, then
plastic bead blast as follows:

1 Hold the spray head of the blast machine at a distance of 12 to 24 in.

(305 to 610 mm) from the surface to be blasted.

2 Hold at an angle of about 45 degrees.

3 Plastic bead blast at a pressure of 40 to 60 psi (2,76 to 4,14 bar).

(b) If the plastic media used is MIL-P-85891 Type II with 54 - 62 Barcol

hardness, then plastic bead blast as follows:

1 Hold the spray head of the blast machine at a distance of 18 to 24 in.

(457 to 610 mm) from the surface to be blasted.

2 Hold at an angle of about 45 degrees.

3 Plastic bead blast at a pressure of less than 40 psi (2,76 bar).

(4) The blasting time must be restricted to the minimum required to remove the paint. AIR OCEAN MAROC
Excessive blasting can damage or remove the protective surface
pre-treatment or cause damage to the underlying metal.

WARNING: CHEMICALS USED IN THIS PROCESS ARE HAZARDOUS. BEFORE USE,

MAKE SURE THAT YOU KNOW THE SAFETY PRECAUTIONS AND FIRST
AID INSTRUCTIONS ON:
- THE LABEL ON THE CONTAINER IT WAS SUPPLIED IN
- ITS MATERIAL SAFETY DATA SHEET
- YOUR LOCAL SAFETY REGULATIONS.
NOTE: This procedure has two stages. During stage 1 (immersion), the half hub is fully
below stripper liquid (in the stripper tank) for sufficient time to make the paint
layers soft. During stage 2 (peachstone blast), the soft paint layers are removed
with a blast of peachstone.

(1) Do stage 1 (Immersion)

(a) The solution must be heated to a temperature of between 35 and

45 deg. C (95 and 113 deg. F).

(b) Put the painted half hub below the stripper solution (in tank) to make the paint
soft.

(c) The half hub must be immersed for less than four hours.

(d) After immersing for minimum time necessary, remove the half hub from the
stripper tank and rinse fully in an adjoining tank containing water at 40
to 50 deg. C (104 to 122 deg. F).

(2) Do stage 2 (Peachstone blast)

(a) After rinsing fully, the half hub must be placed in a blasting chamber.

(b) Hold the spray head of the blast machine at a distance of 4 to 12 in.
(102 to 305 mm) from the surface to be blasted. Remove the paint layers.

(c) Peachstone blast at a pressure of 30 to 45 psi (2 to 3 bar).
