Autoparts 50 inch Deck Spindle Assembly 110-6866 117-1192 Replacement for Toro Timecutter Z4200 Z4202 Z4220 Z4235 Z5020 3 Pack

What It Is

This is a 3-pack of replacement spindle assemblies for 50-inch cutting decks, designed to mount the blades and transfer power from the belt. It’s intended for Toro Timecutter zero-turn mowers that use OEM part numbers 110-6866 or 117-1192.

Fitment & Compatibility

• Check your deck size first: This fits only 50-inch decks. Measure your deck width (blade tip to blade tip) or look for a “50” in the model number.
• Exact model list: Toro Timecutter Z4200, Z4202, Z4220, Z4235, Z5020. Also compatible with some 50" Toro Titan and Z-Master models—verify your OEM part numbers.
• OEM cross-reference: Replaces Toro 110-6866 and 117-1192. This is an aftermarket part, not genuine Toro.
• Physical dimensions: Each spindle has a 1-inch shaft diameter, 1.25-inch top bearing OD, and uses 5/16-24 threaded mounting bolts. Measure your old spindle height (approx. 5.5 inches) to confirm.

Key Things to Know

• Quality variance: With only 5 reviews and a 3.8 rating, expect potential inconsistencies in bearing quality or shaft hardness compared to OEM. Some users report shorter lifespan.
• Installation difficulty: Moderate. You’ll need a socket set, torque wrench (40-50 ft-lbs for mounting bolts), and a puller for stubborn spindles. Don’t reuse old lock nuts.
• Common gotcha: The pulley bolt may be reverse-threaded on some Toro decks—check before forcing. Also, ensure blade bolts are torqued to spec (70-90 ft-lbs) to prevent wobble.
• Warranty: Aftermarket parts typically carry no warranty. Test spin each spindle by hand before installing to check for roughness.

Should You Buy It

Buy this if you need a budget-friendly 3-pack to refresh a worn 50-inch Timecutter deck and you’re comfortable with basic mechanical work and potential shorter service life. Skip it if you want OEM reliability, need parts for a different deck size, or prefer a single-unit replacement to test quality first.
