8TEN Deck Spindle Kit for Toro TimeCutter MX5475 5475C 54-Inch 139-3214 138-7261 117-7268

What It Is

This is a replacement deck spindle kit designed for Toro TimeCutter MX5475 and 5475C zero-turn mowers with 54-inch cutting decks. It houses the blade spindle assembly and bearings that drive the mower blades, replacing worn or failed OEM parts (139-3214, 138-7261, 117-7268).

Fitment & Compatibility

• Direct fit for: Toro TimeCutter MX5475 and 5475C models with 54-inch decks only. Not for 50-inch or 60-inch decks.
• OEM cross-reference: Replaces Toro part numbers 139-3214, 138-7261, and 117-7268. Verify your mower’s deck spindle part number matches one of these.
• Measurements: Spindle shaft diameter is 1-inch; bolt pattern is 3-bolt, 3.25-inch center-to-center. If your deck uses a 4-bolt spindle or different shaft size, this won’t fit.
• Check before buying: Remove one old spindle and compare bolt pattern and shaft length. Also confirm your deck model number (stamped on deck) matches MX5475 or 5475C.

Key Things to Know

• Quality: 8TEN is an aftermarket brand. This kit includes pre-greased bearings and a new pulley, but some users report slightly shorter bearing life than OEM Toro spindles.
• Installation difficulty: Moderate. You’ll need a socket set, torque wrench (specs: 30-40 ft-lbs for spindle bolts), and possibly a puller to remove the old spindle if rusted. Budget 1-2 hours for all three spindles.
• Common gotcha: The pulley may need a spacer or washer if your deck uses a different pulley height. Check old vs. new pulley stack height before final assembly.
• Warranty: 8TEN offers a 1-year limited warranty, but read the fine print—it may not cover bearing wear from normal use.

Should You Buy It

Buy this kit if you need a budget-friendly replacement for a worn spindle on your TimeCutter MX5475 or 5475C and are comfortable with a moderate DIY install. It’s a good value compared to OEM spindles (typically $40-60 each), but skip it if you want maximum longevity or have a different deck size—stick with OEM in those cases.
