Regular greasing through the zerk fitting is a simple way to extend service life. Avoid rough impacts and ensure blades are balanced to reduce stress on the spindle.

• Pre-greased for initial operation
• Zerk fitting for routine grease injections
• Dust cover helps keep debris away from the bearing area
• Recommended: periodic inspections and grease every season or per use intensity

How do I confirm I’m ordering the correct fourtry spindle?

Matching the replacement to your existing part number or checking the mower’s service manual is the fastest way to confirm fit. Compare mounting hole pattern, shaft diameter, and overall spindle height to your current unit. If you’re unsure, a quick photo of the old spindle can help technical support verify compatibility.

• Compare OEM numbers: 918-06991, 618-06991, 285-216
• Measure bolt spacing and shaft size if part number is absent
• Use model lists for Craftsman, Troy Bilt, MTD, Huskee shown above
