wyevee 54-inch Mower Spindle Assembly for Cub Cadet MTD Troy-Bilt — Pre-Greased Bearing, Pulley & Bolts

This wyevee 918-04608A spindle assembly is a direct-fit replacement for 54-inch Cub Cadet, MTD and Troy-Bilt mower decks, built with pre-greased fittings and threaded mounting for straightforward installation and long-lasting performance.

If your lawn tractor’s 54-inch deck is producing vibration, uneven cuts, or noisy operation, a worn spindle assembly is often the culprit. The wyevee 918-04608A / 918-0671 series spindle is engineered to match OEM mounting patterns and dimensions so you can restore smooth blade rotation without modifying the mower. The unit ships with the pulley nut and four threaded mounting bolts and uses a six-point star blade mount to keep blades secure and balanced.

How will this spindle improve my mower’s cutting performance?

Replacing a degraded spindle reduces wobble and blade runout, producing a cleaner, more even cut across the full width of the 54-inch deck. The pre-greased bearing and grease fitting let you maintain lubrication, which helps preserve bearing life and consistent blade speed under load.

• Pre-greased bearing with grease fitting for routine lubrication
• Star-shaped six-point blade mount for stable blade attachment
• Pulley and nut included to restore belt alignment and tension
• Dimensions matched to OEM: 7-7/8" height, 5-3/7" pulley diameter, 5" mounting hole spacing

This spindle is made to replace multiple OEM part numbers and works with many 54-inch deck models from Cub Cadet, MTD and Troy-Bilt. Confirm your deck size and part number before ordering to ensure a correct match.

What should I expect during installation and maintenance?

Installation is intended to be direct: the mounting holes are threaded and the kit includes the pulley nut and four bolts. Routine maintenance is straightforward—periodic greasing through the fitting extends bearing life and preserves quiet operation.

• Threaded mounting holes and included mounting bolts speed installation
• Use included pulley nut for correct belt alignment and retention
