PetMigo spindle assembly 3-pack for 42" & 54" mower decks — direct-fit replacement, restores bearings and hub

If your lawn tractor or riding mower has a worn or noisy spindle, this PetMigo replacement kit restores the hub and bearing assembly used across many Craftsman, AYP, Poulan and Husqvarna models. Designed as a direct-fit aftermarket spindle set, the three-pack covers common deck sizes and replaces several factory part numbers so you can get back to a smooth, even cut without machining or reconfiguring your mower.

Which mower models and deck sizes does this spindle assembly fit?

This spindle assembly was engineered to match bolt patterns and shaft dimensions for a wide range of consumer and commercial-style tractors. It fits 42", 46", 48" and 54" decks for many Craftsman/AYP and Husqvarna machines and several Poulan models, making it a flexible service part for mixed fleets.

• Compatible with AYP, Craftsman and Husqvarna 42"–54" decks.
• Fits multiple model families: YT, YTH, Z, YS, LT and RZ series.
• Works with Poulan models such as PB14538 and PB17542 variants.

How does installation and replacement usually go?

Most owners can swap the spindle using basic hand tools in an afternoon; no specialized machining is required. Remove the deck and old spindle hub, press or tap out the shaft, then install the replacement spindle with new bolts and proper torque. If bearings are press-fit, heating the housing or using a bearing press speeds the job and prevents seal damage.

• Standard hardware and mounting pattern match OEM locations.
• Requires common tools: socket set, torque wrench, bearing press or mallet for seating.
• Replacing three spindles at once saves time versus single-unit replacement.

What OEM numbers and aftermarket cross-references does this kit replace?

The PetMigo spindle assembly is cross-referenced to numerous factory and aftermarket part numbers so you can verify fit before purchase. It replaces popular OEM codes and several third-party equivalents used by Oregon, Stens and Ariens, covering many commonly worn spindle variants.

• Replaces 532187292, 532192870, 587125401 and 539112057.
• Cross-references include Oregon 82-026, Stens 285-585 and Rotary 11590.
• Also fits Ariens and Dixon part number references for similar applications.

Who is this for: technicians, DIY mower owners, and small landscaping businesses that service Craftsman, AYP, Poulan and Husqvarna tractors will find this 3-pack valuable for maintaining multiple machines or stockpiling a trusted replacement. It’s ideal when multiple spindle failures occur or when you prefer replacing all deck spindles at once to ensure even cutting and balanced blade speeds across the deck. Choose this PetMigo spindle set if you need an economical, direct-fit alternative to OEM parts that restores deck stability and reduces future downtime.
