GCCSJ Lawn Mower Spindle Replacement Part Number GY21098 GY20454 GY20867 GY20962 AUC15811 GY21099 GY20893 GY20592 Compatible with John Deere 115 D140 E110 LA115 X126 Sabo 92H Riding Mower,2 Pack

What It Is

This is a 2-pack of aftermarket lawn mower spindle assemblies designed to replace the OEM spindles on select John Deere and Sabo riding mowers. The spindles house the bearings that spin your mower blades, and they’re a common wear item on mid-duty residential decks.

Fitment & Compatibility

Before buying, verify your mower’s model and deck size. This spindle fits John Deere models like the D140, E110, LA115, X126, and 115, plus the Sabo 92H. It replaces OEM part numbers GY21098, GY20454, GY20867, GY20962, AUC15811, GY21099, GY20893, and GY20592. Critical check: measure your deck’s spindle bolt pattern (typically 3-bolt, 2.25-inch center-to-center on these models) and the spindle shaft diameter (commonly 5/8-inch or 3/4-inch). If your deck uses a 4-bolt pattern or a square shaft, this won’t fit. Also confirm your blade mounting hole matches (usually 5/8-inch or 1-inch) – mismatched blades won’t install.

Key Things to Know

• Quality: Aftermarket spindles often use standard bearings that can be replaced individually, unlike some sealed OEM units. Check if the included bearings are greasable (most are not) – if you mow heavy or wet grass, consider adding grease fittings yourself.
• Installation difficulty: Moderate – you’ll need a jack, socket set, and possibly a puller for stubborn spindles. Expect 30–60 minutes per spindle. Torque the mounting bolts to 30–40 ft-lbs; overtightening can warp the housing.
• Common gotchas: The spindle pulley may need to be swapped from your old spindle if the new one’s pulley diameter doesn’t match your belt path. Also, aftermarket spindles can have slightly different shaft lengths – verify blade clearance (1/4-inch above deck) before tightening.
• Pack contents: You get two complete spindles with bearings and pulleys pre-installed. No hardware (bolts, lock washers) is included – reuse your original or buy new Grade 8 hardware.

Should You Buy It

If you own one of the listed John Deere or Sabo models and your deck spindles are wobbling, noisy, or leaking grease, this 2-pack is a cost-effective fix. It’s ideal for DIYers who want to replace both spindles at once (common on 42-inch decks) without paying OEM prices. Skip it if you need a 4-bolt pattern, a specific brand match (e.g., genuine John Deere), or spindles with grease zerks.
