Product Description

The TROY-BILT KH-24-025-121-S is a flywheel assembly designed for use in Troy-Bilt lawn and garden equipment engines. The flywheel is a rotating mass mounted on the crankshaft that stores kinetic energy to maintain consistent engine rotation between power strokes. It also works with the ignition system to generate the spark timing signal needed for combustion. This part is installed by small engine technicians and experienced equipment service professionals performing engine rebuilds or ignition system repairs.

This flywheel assembly is suited for Troy-Bilt lawn and garden power equipment applications. It is a direct OEM-style replacement intended for engines found in walk-behind mowers, lawn tractors, and similar outdoor power equipment that use the compatible engine platform. Installation typically occurs during engine overhaul, ignition troubleshooting, or when the original flywheel shows signs of damage such as sheared keyways or cracked fins.

Key Features

OEM-style flywheel assembly engineered to factory specifications for accurate fit and function
Maintains engine timing integrity by interfacing correctly with the ignition module
Replaces a worn or damaged flywheel without requiring modification to the engine block
Designed for the small-displacement engines common in Troy-Bilt lawn and garden equipment

Compatibility

Designed as an OEM-style replacement flywheel assembly for Troy-Bilt lawn and garden equipment engines. Consult the equipment model and engine serial number to confirm fitment before installation.

Installation Notes

Installation should be performed by a qualified small engine technician. Disconnect the spark plug wire and ensure the engine is fully cooled before beginning work. A flywheel puller tool and torque wrench are typically required for safe removal and proper reinstallation. Inspect the crankshaft keyway and flywheel key for damage before seating the new flywheel, as a sheared key will cause incorrect ignition timing even after replacement.
