POSEAGLE Spindle Assembly Kit for Craftsman 42" & 46" Decks — 2-Pack 587819701, Complete Spindles with Pulleys

POSEAGLE 2 Pack 587819701 is a replacement spindle assembly kit engineered to restore cutting performance on Craftsman, Husqvarna, Poulan and compatible 42" and 46" mower decks.

This pair of spindle assemblies and matching spindle pulleys is a direct-fit aftermarket replacement for many OEM part numbers, built to match original mounting, belt path, and pulley dimensions so your deck spins true again. The kit addresses worn spindle bearings, damaged housings, or cracked pulleys that cause vibration, poor cut quality, or belt slippage. Below we explain what’s included, how it fits, and practical installation details to help you confirm compatibility and plan the replacement.

What parts come in the POSEAGLE 587819701 kit and why they matter?

The kit includes two complete spindle assemblies with pulleys sized to OEM specifications so blade spacing and belt alignment remain correct. Replacing both spindles at once reduces uneven wear and keeps deck balance consistent.

• Two spindle housings with integrated shafts and bearings for reliable rotation.
• Two spindle pulleys (OD 6.23", ID 0.6", height 0.98") matching listed OEM pulleys.
• Fasteners and seals designed to fit the specified mower models (verify included hardware before installation).

How do I know this kit fits my mower model?

POSEAGLE lists extensive cross-references to Craftsman, Husqvarna, Ariens, Poulan and Jonsered OEM numbers; check your mower’s parts manual or existing spindle stamping. Fitment is confirmed when your model and deck size appear in the compatibility list and the pulley measurements match your current pulley.

• Compatible with many 42" and 46" mower decks—see model lists for Craftsman, Husqvarna, Poulan, Ariens, Jonsered.
• Pulley dimensions (OD 6.23", ID 0.6", height 0.98") match common OEM pulleys for these decks.
• Compare part numbers stamped on worn spindles to the cross-reference OEM numbers provided.

How difficult is installation and what tools will I need?

Installation is moderate difficulty and typically requires basic hand tools plus a torque wrench for correct fastener tightening. If you have lifted the deck and removed blades before, this job follows similar steps: secure the deck, remove blades, unbolt the old spindle, transfer pulleys if needed, and install the new spindle assemblies.

• Common tools: socket set, torque wrench, breaker bar, blade puller or heavy glove for safety.
• Time estimate: 1–2 hours for both spindles for a DIYer with basic experience.
• Follow torque specs from your mower manual and verify belt routing after reassembly.

What improvements should I expect after installing these spindles?

Replacing worn spindles restores smooth blade rotation, reduces vibration, and helps achieve an even, clean cut across the deck. Correctly matched pulleys keep belt alignment and tension consistent, reducing premature belt wear and noise.

• Reduced vibration and wobble during operation.
• Improved cut quality and consistent deck height across the mowing width.
• Extended life for belts and blades when alignment is restored.

Who is this for: This POSEAGLE 2 Pack 587819701 spindle assembly kit is aimed at homeowners and small-property landscapers who maintain Craftsman, Husqvarna, Poulan or compatible lawn tractors with 42" or 46" decks. It suits DIY mechanics who want a cost-effective direct replacement for worn or damaged spindles and pulleys, and fleet-maintenance technicians seeking consistent parts cross-referenced to multiple OEM numbers. Always confirm model compatibility and pulley measurements before purchase; if you’re unsure, capture your current spindle model number or a clear photo and compare to the listed OEM references to ensure a correct fit.
