Product Description

The TECUMSEH 570649A is an O-ring seal designed for use in Tecumseh small engine assemblies.

This part is a direct OEM replacement item intended for licensed small engine technicians and qualified service professionals performing engine rebuilds, carburetor service, or component reassembly on Tecumseh-powered equipment. Proper sealing at each O-ring location is critical to maintaining correct compression and fluid integrity throughout the engine or fuel system.

Installation Notes

Installation is typically performed by a small engine technician. Shut off the fuel supply and allow the engine to cool completely before disassembly.
