How do these replacement parts improve mower performance?

Replacing worn drive wheels and pinion gears restores traction, wheel engagement and consistent speed control across lawns. The metal pinion gears provide robust tooth engagement while the rubberized wheel tread recovers grip on turf.

• Rubber tread over a plastic wheel body for traction without tearing turf.
• Metal 15T pinion gears resist wear better than softer materials.
• Restoring both wheels and gears prevents premature wear on the mating components.
• Low maintenance — designed for long service life under normal use.

What’s included and what are the key dimensions?

The kit supplies what you need to replace two rear drive assemblies: two 8" wheels and two matching pinion gears. Dimensions are provided to help confirm correct fitment with your mower’s axle and gearbox.

• Package contents: 2 rear drive wheels + 2 metal 15T pinion gears.
• Wheel diameter: 8" (approx. 203 mm); width: 2" (approx. 51 mm).
• Bore diameter: 1/2" (approx. 12.7 mm); gear diameter: ~3.32" (~84 mm).
• Plastic wheel body with rubber tread and 52 teeth on the wheel hub for engagement.

How simple is installation and what tools are required?

Installation is straightforward for most DIYers familiar with small mower maintenance. In many Toro models the rear wheels and pinion gear can be swapped with common hand tools, though exact steps vary by model.

• Typical tools: wrench set, pliers and possibly a flat-head screwdriver to release clips.
• Remove old wheel and gear, slide new pinion onto shaft, secure wheel to axle and reattach any retaining clips.
• Follow your mower’s service manual for torque specs and safety procedures.
• If unsure, seek help from a small-engine technician to avoid damage.

Who is this for: This sanbaiyi wheel and pinion gear kit is intended for Toro 22" recycler owners who need a reliable aftermarket replacement for worn rear drive components.
