Troy-bilt 717-04129A Pinion Gear 16 Tooth

Product Description

The TROY-BILT 717-04129A is a 16-tooth pinion gear designed for use in Troy-Bilt lawn and garden equipment drive systems. Pinion gears transmit rotational force within a gear assembly, converting motor output into wheel or blade movement. This component is a direct OEM-style replacement part, suited for installation by small-engine equipment technicians or experienced DIYers performing drivetrain service. The 16-tooth specification is critical for proper gear mesh and ratio — using an incorrect tooth count will result in drive failure or component damage.

This pinion gear is used in Troy-Bilt lawn and garden equipment where drivetrain components require replacement due to wear, damage, or failure. Typical applications include self-propelled walk-behind mowers, lawn tractors, and similar gear-driven outdoor power equipment. It fits within the gear and wheel assembly of supported Troy-Bilt models and is the correct OEM part number for the intended application.

Key Features

Installation Notes

Installation should be performed by a qualified small-engine technician or a knowledgeable DIYer familiar with outdoor power equipment drivetrain service. Disconnect the spark plug wire and, where applicable, remove stored energy from the drivetrain before disassembly. Basic hand tools are typically required; refer to the equipment service manual for the correct disassembly and reassembly sequence. Ensure the replacement gear seats fully and meshes correctly with mating gears before returning the equipment to service.
