- Locate the Serial Number: The most important rule is that the manual must match the machine's serial number. The S120 was produced over many years; using the wrong manual will result in incorrect part numbers.
- Identify the Group: Use the table of contents to find the general group (e.g., "Front Axle").
- Locate the Illustration: Find the page with the diagram that looks like the component you are working on.
- Cross-Reference: Find the item number on the diagram, then look to the parts list below it to find the part number and description.
- Verify with the Dealer: When ordering, provide the dealer with both the part number and your machine’s serial number to double-check compatibility.

4. Applications in Maintenance
The manual serves three primary maintenance roles:
- Troubleshooting: By looking at the hydraulic or electrical schematics, a technician can trace the flow of fluids or current to identify potential failure points.
- Repair Planning: The "exploded" views help mechanics understand the sequence of disassembly. For example, seeing that a retaining ring must be removed before a pin allows for faster, safer repairs without damaging surrounding components.
- Parts Procurement: The manual provides the OEM (Original Equipment Manufacturer) Part Number. Even if buying aftermarket parts, having the OEM number is essential to cross-reference compatibility with third-party suppliers.
Cross-Referencing Part Numbers
One of the hidden superpowers of the Sellick S120 parts manual is the cross-reference index. Sellick does not manufacture every component. They assemble.
- Bearings: Often Timken or SKF. The manual gives the Sellick number (e.g., SEL-5880) and the industry standard (e.g., LM11949).
- Seals: Usually CR or National. You can buy these at any bearing supply house once you have the manual’s dimensional data.
- Filters: The manual will list cross-reference to Fleetguard, Baldwin, or WIX.
Important: Do not cross-reference hydraulic hoses. Sellick uses specific bend radii and lengths. An off-the-shelf hose will rub against the mast channel and burst.
