What It Is

This deck rebuild kit supplies all wearable components needed to restore a 46-inch cutting deck on select Troy-Bilt and MTD lawn tractors. It includes two spindle assemblies, two blades, two idler pulleys, and one drive belt—everything for a full deck overhaul.

Fitment & Compatibility

Before purchasing, confirm your mower’s deck size is exactly 46 inches. This kit is designed for Troy-Bilt models T1500, T1600, LT 4600, CLT46CVT, and TB46, plus MTD equivalents. Check your spindle part numbers: OEM 618-06989 or 918-06989. Blades must match 742-04244 or 742-04290. The belt is 754-04219. Measure your existing belt length (typically 96.5 inches) and verify idler pulley part GY22082. This is an aftermarket kit, not OEM, but uses standard bolt patterns. Ensure your deck’s spindle mounting holes align with the included spindles (most 46-inch MTD/Troy-Bilt decks do). If your tractor uses a different belt routing or spindle height, it won’t fit.

Key Things to Know

• Quality: Aftermarket parts are generally reliable, but spindles may have slightly thinner bearings than OEM. Check grease fittings—some kits lack them, requiring manual greasing.
• Installation Difficulty: Moderate. You’ll need a socket set, jack stands, and possibly a puller for old spindles. Plan 2–3 hours. The belt routing diagram is critical—take a photo before removal.
• Common Gotchas: Old spindles may be seized; penetrating oil and heat help. Blade bolts often require a torque wrench (40–50 ft-lbs). Idler pulleys must spin freely—test before mounting. The belt may need adjustment after a few hours of use.
• What’s Not Included: No hardware (bolts, lock washers) for spindles or blades. Reuse originals or buy separately.

Should You Buy It

If your 46-inch Troy-Bilt or MTD deck is vibrating, cutting unevenly, or the belt is slipping, this kit is a cost-effective fix. It’s ideal for DIY owners who want a single purchase to replace all wear items at once. Not for decks with damaged housings or non-standard bolt patterns.
