How does this replacement improve steering performance?

Replacing a worn sector gear and pinion restores direct mechanical engagement between the steering shaft and the steering linkage, reducing play and restoring predictable wheel response. The DVPARTS unit is machined to match original dimensions so it meshes cleanly with existing steering components.

• Reduces steering play by replacing worn teeth and plate surfaces.
• Restores alignment and helps maintain straight tracking.
• Durable construction resists wear under normal mowing use.

What part numbers and cross-references should I compare?

The product carries several cross-reference numbers, which makes it easier to confirm a match with your mower’s service parts. Compare the stamped or printed part number on your existing sector plate to these listed references.

• Primary DVPARTS: 717-1550 and variant suffixes (717-1550A through 717-1550F).
• Additional cross-references: 917-1550E and 917-1554.
• Use these numbers when checking OEM diagrams or parts lists for your tractor model.

What should I consider before installation?

Installation requires basic mechanical skills and common hand tools; typical steps include removing the mower’s steering wheel and covers, detaching the old sector plate, and transferring any linkage hardware to the new plate. Inspect adjacent steering components and fasteners while the unit is removed and replace worn bushings or cotter pins as needed.

• Confirm part number compatibility and orientation before disassembly.
• Keep track of shims, washers, and hardware for correct reassembly.
• Test steering free play and tracking after installation; adjust tie rods if required.

Who is this for: This DVPARTS steering sector gear plate and pinion is aimed at homeowners, landscapers, and small-fleet technicians who need a direct-fit steering replacement for MTD-built and compatible Cub Cadet or Troy-Bilt riding mowers. It suits anyone comfortable with mid-level mower repairs who wants to replace a worn steering assembly with a cost-effective aftermarket part that mirrors OEM specifications.
