boeray Spindle Assembly for Cub Cadet & MTD 42in/30in Decks — 6-7/8" Length, 6" Pulley, Preassembled with Zerk

boeray spindle assembly is a direct-fit replacement spindle unit for many Cub Cadet and MTD 30" and 42" mower decks, supplied complete with pulley, tapped bolts, zerk grease fitting, and dust cover.

If your mower deck wobbles, cuts unevenly, or makes grinding noises, the spindle assembly is often the worn component behind the problem. This boeray unit is manufactured to match the common mounting pattern and pulley size used on a wide range of Cub Cadet, MTD and compatible mini rider and zero-turn models from recent years. It arrives with the fasteners and fittings you need to replace the assembly without searching for extra parts.

How do I know this spindle fits my mower?

Verify fit by comparing three key measurements: overall length, mounting hole center-to-center distance, and pulley diameter. The boeray spindle measures 6-7/8" (174 mm) long, has 5" (127 mm) between mounting holes, and uses a 6" (152 mm) diameter pulley with a 1/2" width. It’s intended as a substitute for many factory part numbers listed for Cub Cadet and MTD units.

• Overall length: 6-7/8" (174 mm)
• Mounting hole spacing: 5" (127 mm)
• Pulley diameter: 6" (152 mm), width: 1/2"
• Compare against your original spindle dimensions before installation

Which mower models and part numbers does this replace?

This assembly is designed to substitute many OEM part numbers across Cub Cadet, MTD and related brands. It lists compatibility with a range of mini riders, LTX and RZT series machines as well as numerous 42-inch lawn tractors and select zero-turn models from around 2010 forward. Check the part references on your old spindle for a match.

What comes in the package and how does it help installation?

The boeray spindle assembly ships as a ready-to-install unit including the pulley, threaded mounting hardware, a grease (zerk) fitting, and a protective dust cover. Hardware compatibility and the pre-tapped bolt pattern reduce time spent sourcing additional parts, while the zerk port allows straightforward lubrication for ongoing serviceability.

• Includes pulley, tapped screws, grease zerk fitting, and dust cap
• Designed for 6-point star spindle shafts for improved stability
• Pre-assembled elements expedite bench or in-deck replacement
• Zerk fitting enables routine greasing without disassembly

What should I expect during and after replacement?

Installing this spindle typically restores a stable, quieter deck operation and even blade rotation when it was previously affected by worn bearings or a damaged spindle. After replacement, torque the mounting fasteners to the manufacturer’s specification and lubricate through the zerk fitting. Inspect belts and blades for wear while the deck is accessible to complete the service.

• Re-check belt alignment and blade balance after assembly
• Tighten mounting bolts to factory torque values
• Grease through the zerk fitting as part of first use
• Test-cut a small area to confirm proper operation

Who this is for: This boeray spindle assembly is aimed at owners and technicians who maintain Cub Cadet, MTD, and compatible mini rider or 42" lawn tractor decks and need a reliable replacement spindle with included hardware. It suits DIY mechanics replacing a worn spindle, fleet maintainers seeking a standardized spare, and anyone who prefers a complete kit that reduces parts hunting.
