2 Pack 918-06991 Spindle Assembly with 756-05034A Idler Pulley 954-04060C Belt 490-900-M061 Deck Wash Kit Replaces 618-06991 for Craftsman T110 T1200 Huskee LT4200 Troy Bilt Bronco 42" Decks

What It Is

This is a 2-pack of 918-06991 spindle assemblies plus an idler pulley, belt, and deck wash kit—a complete replacement set for the cutting deck’s blade drive system on 42-inch Craftsman T110/T1200, Huskee LT4200, and Troy-Bilt Bronco mowers. It’s designed to restore blade rotation when spindles are worn or seized, and the belt/pulley refresh prevents slipping or squealing.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch stamped steel deck—this kit will not fit 46” or 54” decks. Check the OEM part numbers on your current spindles: they should read 918-06991 or 618-06991 (the old number). The included idler pulley (756-05034A) and belt (954-04060C) are direct replacements for those specific parts. Measure your existing belt length if possible—it should be about 96 inches. This is an aftermarket kit, not OEM, so verify the mounting hole pattern (3-bolt, 3.5-inch center-to-center) matches your deck. Models like Craftsman T110, T1200, Huskee LT4200, and Troy-Bilt Bronco with 42” decks are confirmed fits.

Key Things to Know

• Quality: Aftermarket spindles are generally fine for residential use, but the bearings may not last as long as OEM. Expect 2-3 seasons under normal mowing.
• Installation difficulty: Moderate. You’ll need a socket set, jack or blocks to lift the mower, and possibly a puller to remove old spindles. Budget 1–2 hours.
• Common gotcha: The deck wash kit is a nice bonus, but the plastic fitting can crack if over-tightened. Hand-tighten only.
• Belt routing: The belt is included, but check your deck’s belt diagram—routing mistakes cause slipping or premature wear. Take a photo before removing the old belt.

Should You Buy It

If your 42” Craftsman, Huskee, or Troy-Bilt mower has noisy, wobbly, or seized spindles, this kit is a cost-effective fix for a single-season or two. It’s not built for heavy commercial use, but for residential lawns under an acre, the price and completeness (spindles, pulley, belt, wash kit) make it a solid value. Just confirm your deck model and hole pattern first.
