Aeagle 46-inch Mower Spindle 2-Pack — Direct-Fit for MTD/Cub Cadet, Pre-Mounted Pulleys

High-strength replacement spindle assembly for 46-inch mower decks — two complete spindles with pulleys engineered to fit MTD, Cub Cadet, Craftsman and compatible Troy-Bilt models.

If your 46" deck has a worn or damaged spindle, this Aeagle 2-pack restores reliable blade rotation and deck performance. Each assembly matches OEM dimensions and fitments for part numbers including 918-06977, 918-06977A, 618-06977 and 618-06977A, and comes with pre-mounted pulleys so installation is straightforward. These spindles are manufactured to the listed height and pulley diameter to ensure proper belt alignment and cutting geometry on a wide range of walk-behind and riding mowers.

How do the dimensions and components affect installation?

These spindles are matched to common OEM dimensions so the belt tracking and blade height remain consistent after replacement. Key measurements reduce the need for shims or modifications for most correct-fit applications.

• Spindle overall height: 6-1/2 inches (164 mm) to align with factory deck geometry
• Pulley outer diameter: 6-1/4 inches (160 mm) for proper belt engagement
• Each package includes two spindle housings and two pulleys for dual-blade decks

What materials and build quality should I expect?

Aeagle spindles are built for the stresses of blade rotation and deck vibration, using hardened shafts and corrosion-resistant housings. They are intended as direct replacements rather than aftermarket redesigns, so longevity and fitment are prioritized.

• Machined spindle shaft for concentric rotation and reduced vibration
• Durable pulley fitted to factory dimension to protect belts
• Stamped or cast housing designed to accept OEM mounting hardware

What should I check before and after installing these spindles?

Proper pre-install checks and post-install adjustments keep the deck cutting even and extend component life. Follow safe maintenance practices and use manufacturer torque specs where available.

• Verify part numbers and mower serials against the compatibility list before buying
• Inspect mounting bolts, spindle bearings, belt condition, and blade balance during replacement
• After installation, confirm belt alignment and spin the blade by hand to check for rubbing or wobble

Who is this for: This Aeagle 2-pack spindle assembly is aimed at homeowners, landscapers and repair technicians who need a factory-dimension replacement for 46" mower decks. It’s ideal if you own one of the listed Cub Cadet, MTD, Craftsman or compatible Troy-Bilt models and require a direct-fit spindle/pulley set to restore deck performance without complex modifications.
