ECCPP 2 pack Mower Spindles fit for AYP/for ROPER/for SEARS: 137646, 532137646, for Husqvarna: 532137646, for OREGON: 85-017, for PRIME LINE: 7-05275, for Stens: 285-464, for SUNBELT: B1RS21

What It Is

This is a 2-pack of replacement mower spindles (the assembly that houses the blade and bearing, connecting it to the deck). Designed for residential riding lawn mowers, it directly replaces OEM part numbers for AYP, Roper, Sears, Husqvarna, and several aftermarket brands.

Fitment & Compatibility

Before buying, confirm your mower uses a 3.5-inch diameter spindle housing and a 5/8-inch hex shaft for the blade. This pack fits many 42-inch and 46-inch decks from AYP, Roper, and Sears (models using OEM #137646 or 532137646), plus Husqvarna models using the same OEM number. It’s also a direct cross for Oregon 85-017, Prime Line 7-05275, Stens 285-464, and Sunbelt B1RS21. Measure your spindle housing diameter and shaft size—if your deck uses a different pattern (e.g., 4-inch housing or 1-inch shaft), this won’t fit. Check your mower’s model number against the OEM parts list.

Key Things to Know

• Bearing quality: These are budget-friendly spindles; bearings may not last as long as OEM or premium aftermarket (Stens, Oregon). Expect 1-2 seasons under heavy use.
• Installation: Moderate difficulty—requires removing blades, pulleys, and bolts. Use a torque wrench for spindle bolts (typically 30-40 ft-lbs). Grease fittings are present but may need additional grease before install.
• Blade bolt size: The spindle uses a 5/8-inch hex shaft, but check if your blade bolt is 5/8-inch or 1/2-inch—some older decks differ.
• Pack includes two spindles: Good for replacing both on a 2-spindle deck, but verify your deck uses identical spindles (some have left-hand vs. right-hand pulleys).

Should You Buy It

Buy this if you need a quick, low-cost fix for a worn spindle on a residential AYP/Roper/Sears/Husqvarna deck and don’t mind replacing them every couple of years. Avoid if you mow commercially, have a heavy-duty deck, or want long-term durability—spend more on Stens or OEM for better bearings and longer life.
