Guide
The Service Bill of Material (SBOM) tool was designed to assist the user in creating a
customized service parts stocking list for a specific engine or engine configuration
(once a representative Engine Serial Number (ESN) is known).
– The SBOM tool derives the service level parts based on an ESN and certification repair level.
Parts displayed are the most current parts including the supersessions and kits. The SBOM
tool shows the certification repair level (Maintenance, Lite Repair, Repair, Full Service, Master
Service) as well as the recommended stock list for the user’s evaluation.
“Stock List” designations have been added to a small amount of Maintenance, Lite Repair,
Repair and Full Service parts. The “stock list” designation is a best estimate of the highest
probability or typical service event type parts that may be stocked depending on the
certification repair level of the service provider. Service providers will still need to evaluate
the list to determine appropriate coverage.
Service Bill of Material Guide

SBOM Report Attributes
The SBOM list displays the current part numbers, including supersessions and most kits,
needed to service the particular Engine Serial Number. In addition to the parts list, the tool
also displays other attributes for each part number to assist in making decisions on
stocking, such as:
– Part Description
– Certification Service Level (Maintenance, Maintenance Stock List, Lite Repair, Lite Repair
Stock List, Repair, Repair Stock List, Full Service, Full Service Stock List, Master Service)
– ReCon cross reference part number if applicable
– Quantity of part number required per engine
– Current and Future Sales Status Codes
Service Bill of Material Guide
Factors to Consider
Many factors influence a particular stocking list, and these factors should all be considered
when determining a list that best suits a location’s needs. Among those factors are:
– Certification Level of the service provider
– Customer expectations for repair timeliness
– Available working capital to invest in repair parts
– Proximity to regional headquarters, RDCs and PDCs
– Local engine population to be supported with parts inventory
– Historical knowledge of parts that have high turnover
The SBOM tool should NOT be used as a method of determining a “Required” parts
stocking list, but rather serve as a guide for the most common stock/usage type parts that
would likely be beneficial to have on hand to support local customers.
Service Bill of Material Guide
Stock Lists for Certified Locations
Once an SBOM report is generated for a particular ESN, a stocking facility or service
provider can create a part number list based on their certification level using the
precoded/suggested “stock list” parts or historical knowledge of parts with high turnover.
Certified repair locations: If you are certified as:
– Maintenance repair location - you may use the “Maintenance Stock List” parts.
– Lite Repair location - you may use the “Maintenance Stock List” parts plus the “Lite Repair Stock List” parts.
– Repair location - you may use the “Maintenance Stock List” parts plus the “Lite Repair Stock List” parts plus
the “Repair Stock List” parts.
– Full Service location - you may use the “Maintenance Stock list” parts plus the “Lite Repair Stock List” parts
plus the “Repair Stock List” parts plus the “Full Service Stock List” parts.
NOTE: Parts listed as “Maintenance”, “Lite Repair”, “Repair”, or “Full Service” (without the “stock list”
designation) may also be used to build stocking lists.
Service Bill of Material Guide
Stocking Quantities
Once a particular part number stock list with component quantity has been defined, it is necessary to
determine the quantities for each part based on engine population. When determining the part number
quantities, the same local inputs of certification level, customer expectations, available capital, and
location should also be considered. In addition to these factors, you should also know the engine
population being supported.
0-19 1
20-99 2
100-499 3
>500 4
Example: A location is supporting 150 engines of a particular engine configuration.
– They have determined that an oil pan gasket is a part they want to stock. From the table above, they should stock
a quantity of 3 pieces.
– They have determined that an injector is a part they want to stock. From the table above, they should stock a
quantity of 18 pieces (3 X 6 injectors/engine).

SBOM Sorting
The parts in the Excel file can be sorted or filtered so that they appear in Service Level groups
(Maintenance, Maintenance Stock List, Lite Repair, Lite Repair Stock List, Repair, Repair Stock List,
Full Service, Full Service Stock List).

SBOM Sorting
Consider all your local inputs when developing your stocking list:
– Certification level of service provider, customer expectations, proximity to regional
headquarters, engine population, historical knowledge of high turnover parts, availability of
working capital investment, etc.

Tips While Evaluating an SBOM List
1. Filters (fuel, lube, coolant) and Cleaners (air): The SBOM should show the equivalent
Cummins Filtration part number. If a Cummins Filtration part number is not found, you will need to manually
find and add the appropriate part numbers by cross-referencing the SBOM filter part numbers (Cummins
numbers) to Cummins Filtration part numbers using the following website’s cross reference catalog:
http://www.cumminsfiltration.com.
2. ReCon: If ReCon is available, the SBOM should show this p/n in the “ReCon X-ref”
column.
3. Kits: The higher level kit should be shown if the individual component is not salable.
a) In some cases, both the individual component and the kit will be shown if both are salable
(i.e…..front/rear crank seals + crank seal kits)
b) If the kit is not shown, the Service Bill of Material Sales Status Code Training document can be used to
give guidance on how to determine the kit part number.
4. Component Qty: It is suggested to stock the required qty as needed by the engine.
Most quantities required in engine = 1.
a) Note: Certain part numbers with common noun names (capscrews, washers, etc…) may be used multiple
times in an engine. It is suggested to look for these ‘duplicated’ part numbers.

Tips While Evaluating an SBOM List
5. Turbochargers: SBOM may show different structure level turbo part numbers that may not be salable.
However, SBOM should show the turbocharger kit.
9. Gaskets missing: If a particular gasket is missing, check to see if the engine uses FIP (Formed in
Place) gasket material. The service manual should list the appropriate gasket sealant.

Sales Status Code 80 Helpful Notes
Similar logic applies to parts with SSC 80. The SSC 80 means that the lower level components of an assembly
should be purchased or there is a multiple replacement. Many times there are parts with the same noun name
visible on the report (examples… Aftertreatment Device, ECM, Flywheel Housing, Tubes). If a part is status
code 80 because there is a multiple replacement, the service notes will have instructions for the replacement.
