Description
Group 1-2:
1. CONCURRENT REQUIREMENTS
None.
2. BACKGROUND
Accomplishment of this service bulletin will detect and prevent heat damage and possible cracks in the Main
Landing Gear (MLG) truck beam - inner cylinder pivot pins and inner cylinder bushings. If this service bulletin
is not done, the pivot pin could fracture, leading to loss of all or part of the pivot pin assembly and subsequent
loss of the MLG truck and loss of directional control during take off or landing.
Fleet sampling inspection of some airplanes found cracks in the left and right MLG Pivot Pins on one of the
airplanes. The pins exhibited cracking of the High Velocity Oxygen Fuel (HVOF) tungsten carbide - cobalt
- chrome coating. Removal of the outer diameter coating disclosed cracking of the custom 465 CRES sub-
strate. The cause of the cracking was determined to be heat damage due to in-service friction.
This Service Bulletin gives instructions to lubricate and inspect the MLG truck beam pivot pins and inner
cylinder bushings, and where necessary to repair and/or replace damaged pivot pins and bushings. The
new copper-nickel-tin bushing material provides improved frictional performance.
Boeing Service Related Problem (SRP) 787 SRP-32-0232 is related to this service bulletin.

B. Spares Affected
Group 1, Configuration 1:
Examine your spares supply for 512Z2001-1, -2, or -3 Inner Cylinder Assemblies. If any of these Inner
Cylinder Assemblies are found, remove the Aluminum-Nickel-Bronze Inner Cylinder Bushings 512Z3002-
1 and replace with Copper-Nickel-Tin Inner Cylinder Bushings 512Z3002-2. Refer to CMM 32-11-74
as an accepted procedure.
Identify on the part that the change given in this bulletin was done. Use the rubber stamp (Code RO)
or ink jet (Code J) method. Refer to SOPM 20-50-10 as an accepted procedure.

If an airplane has a non-Boeing modification or repair that affects a component or system also affected by
this service bulletin, the operator is responsible for obtaining appropriate regulatory agency approval before
incorporating this service bulletin.
7. Manpower
The table below shows an estimate of the task hours necessary to do this inspection and repair for each
MLG. This estimate is for direct labor only, done by an experienced crew. Adjust the estimate with operator
task hour data if necessary. The estimate does not include lost time. These are some examples of lost
time:
– Time to adjust to the workplace
– Time to schedule the work
– Time to inspect the work
– Time to cure the materials
– Time to make the parts
– Time to find the tools

Group 1-2:
1. GENERAL INFORMATION
KEEP THE WORK AREA, WIRES AND ELECTRICAL BUNDLES CLEAN OF METAL
PARTICLES OR CONTAMINATION WHEN YOU USE TOOLS. UNWANTED MATERIAL,
METAL PARTICLES OR CONTAMINATION CAUGHT IN WIRE BUNDLES CAN CAUSE
DAMAGE TO THE BUNDLES. DAMAGED WIRE BUNDLES CAN CAUSE SPARKS OR
OTHER ELECTRICAL DAMAGE.
CAUTION
NOTE: RC: Start
1. This is an Enhanced Required for Compliance document. There will be a separate Service
Bulletin (SB) and a separate Requirements Bulletin (RB). If an RB is mandated by an Airworthi-
ness Directive (AD), then all applicable requirements specified in the RB must be done. For the
related SB, some locations are marked RC Start and RC End to identify the requirements that
are restated from the RB. For the related SB, the areas between RC Start and RC End, including
sub-steps and any figures identified between RC Start and RC End, must be done to comply
with the AD. Therefore, an Alternative Method of Compliance (AMOC) is required for any devi-
ations to steps between RC Start and RC End, including substeps and identified figures. For
the related SB, the steps not between RC Start and RC End may be deviated from using accepted
methods in accordance with the operator's maintenance or inspection program without obtaining
approval of an AMOC; this is provided that the steps between RC Start and RC End, including
sub-steps and identified figures, can still be done as specified, and the airplane can be put back
in an airworthy condition. Figures not required for compliance are omitted from the RB.
2. This is an Enhanced Required for Compliance document. The Boeing processes used to create
the Service Bulletin (SB) and the Requirements Bulletin (RB) ensure that the information between
"RC Start" and "RC End" in the SB are identical to the information in the same sections (Com-
pliance, Work Instructions...) of the RB which the SB refers to as the related document.
3. These work instructions refer to procedures included in other Boeing documents. When the
words "refer to" are used and the operator has an accepted alternative procedure, the accepted
alternative procedure can be used. When the words "in accordance with" are included in the
instruction, the procedure in the Boeing document must be used.
4. The compliance times for the actions in Work Instructions are in the Compliance section.
5. When more than one OPTION is given for a CONDITION, do only one of the OPTION numbers.
When more than one ACTION is given for a CONDITION number or an OPTION number, do
all of the ACTION numbers for that CONDITION number or OPTION number.

6. The instructions in Work Instructions and the Tasks can include operation of tools or test
equipment. Boeing Engineering Tool Drawings, the Illustrated Tool and Equipment Manual, and
the Special Tool and Ground Handling Drawing Index contain data on versions of the tools or
test equipment that you can use. It is permitted to use replaced tools. It is not permitted to use
superseded tools.
7. A Detailed Inspection is defined as: An intensive examination of a specific item,installation or
assembly to detect damage, failure or irregularity. This could include tactile assessment in which
a component or assembly can be checked for tightness/security. Available lighting is normally
supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection
aids such as mirrors and magnifying lenses may be necessary. Surface cleaning and elaborate
access procedures may be required.
8. Heat damage is defined as ladder cracks, spalling, pull-outs, cracks, chips, flakes, lifting, or
color changes.
9. Friction damage is defined as material transfer on the part surface or other contaminants found.

10. Manual titles are referred to by acronyms. Refer to Data Module SB B787-A-32-00-0045-00A-

11. Obey all of the warnings and cautions given in the specified manual sections.

12. Unless shown differently, these dimensions and tolerances are used:
– Linear dimensions are in inches
– Tolerance on linear dimensions, other than rivet and bolt edge margins, is plus or minus
0.03 inch
– Tolerance on rivet and bolt edge margin is plus or minus 0.05 inch
– Angular tolerance is plus or minus 2 degrees
– Hole dimensions for standard solid rivets and fasteners are in SRM Chapter 51
– Torque Values:
– Values for structural fasteners are given in 787 Structural Repair Manual, Chapter 51.
– Values for airframe maintenance tasks are included in Chapter 20 of 787 Aircraft Main-
tenance Manual (AMM).
– Values for electrical maintenance tasks are included in Chapter 20 of Standard Wiring
Practices Manual (SWPM).
– Values for engine maintenance tasks are included in Chapter 70 of 787 Aircraft Mainte-
nance Manual (AMM).
– Non-standard torque values for maintenance tasks are included in the applicable instal-
lation step.
13. If it is necessary to remove more parts for access, you can remove those parts. If you can get
access without removing identified parts, it is not necessary to remove all of the identified parts.
Jacking and shoring limitations must be observed.
