Companion flange only. A complete PTO output-conversion kit is a separate assembly.
The Parker Chelsea 380503 1410 Series companion flange provides the driveline connection at a compatible Chelsea PTO output. It is a replacement component for an existing flange-style output, rather than a complete power take-off, output shaft, or driveline.
Choose this part using the PTO model and output code as well as the driveline series. The 1410 designation alone does not establish that the flange will fit every PTO shaft. Matching the existing output assembly avoids ordering a flange when the installation actually needs a shaft, bearing-cap, or conversion-kit change.
Service a compatible driveline output
A separately replaceable flange allows the output connection to be serviced without ordering an entire PTO when the remaining components are serviceable. Inspect the shaft, flange connection, retaining hardware, and driveline before selecting replacement parts.

Match the PTO output assembly
Compatible configurations include Chelsea 280 Series XV outputs and 870 Series XV or SV outputs that specify part 380503. These examples are output-specific: a different output option on the same PTO series may use another flange or pump-mount arrangement.
| Component or application |
Selection guidance |
| 280 Series XV output |
Uses the 380503 companion flange; verify the complete PTO model and applicable parts list. |
| 870 Series XV or SV output |
Uses the 380503 companion flange; confirm the output configuration before ordering. |
| Retaining hardware |
Washer 380076-13 and nut 380486 are separate service components; check the applicable assembly requirements. |
| Output conversion |
Select the exact conversion kit when changing output type. This flange is not a complete conversion kit. |
Before ordering
| Check |
Requirement |
| PTO identification |
Provide the full model and output code from the identification plate. |
| Mating components |
Match the shaft interface, driveline series, flange pilot, and mounting pattern. |
| Service condition |
Inspect the shaft and retaining components for wear or damage before reassembly. |
| Installation |
Use the instructions and fastening requirements for the exact PTO output assembly. |
| Safe service |
Stop the engine and prevent unintended movement before working on the PTO or driveline. Keep rotating components properly guarded. |
