618P09236 Spindle Assembly Fits for 54 Inch Decks Cub Cadet ZT1-54 ZT2-54 XT1-ST54 XT1-GT54 ZTS2-54 Craftsman T3200 Z5800 Z7600 Troy Bilt Mustang Z54 54XP Lawn Mower Replaces 618-09236 (3 Pack)

What It Is

This is a 3-pack of OEM-style spindle assemblies for 54-inch zero-turn and lawn tractor decks. It drives the blades on Cub Cadet ZT1-54, ZT2-54, XT1-ST54, XT1-GT54, ZTS2-54, Craftsman T3200, Z5800, Z7600, and Troy-Bilt Mustang Z54/54XP mowers. Replaces OEM part 618-09236.

Fitment & Compatibility

Before buying, confirm your deck is exactly 54 inches—this spindle won’t fit 46-inch or 60-inch decks. Check your mower model suffix (e.g., ZT1-54 vs ZT1-50). For Craftsman and Troy-Bilt, verify the deck is from a compatible series (T3200/Z5800/Z7600, Mustang Z54/54XP). This is an aftermarket replacement for OEM 618-09236, so measure the spindle shaft diameter (commonly 1 inch) and bolt pattern (usually 3-bolt, 4-inch spacing) to match your existing spindle. Also confirm your deck’s pulley size and belt routing match—some deck revisions use different pulley offsets.

Key Things to Know

• Quality vs OEM: These are aftermarket, but rated 4.8/5. Many users report they last as long as OEM if you grease them regularly (most have a grease fitting).
• Installation difficulty: Moderate. You’ll need a socket set, jack or blocks to lift the deck, and a puller to remove the old pulley. Expect 30–60 minutes per spindle.
• Common gotcha: The included bolts may be slightly different thread pitch than OEM. Test-fit before tightening fully—strip a deck housing and you’ll have a bigger job.
• 3-pack value: Buying individually costs 20–30% more. If you have one bad spindle, the other two are spares for future failures (common on 54-inch decks with heavy use).

Should You Buy It

If you own one of the listed Cub Cadet, Craftsman, or Troy-Bilt 54-inch decks and need to replace a worn or wobbly spindle, this 3-pack is a solid value. It’s ideal for DIYers who want to avoid paying $40–$50 per OEM spindle and don’t mind a straightforward afternoon job. Skip it if your deck is a different size or you need a specific OEM warranty match.
