Ryobi 80035003085 Arbor Nut Lawn Mower Part

Product Description

The RYOBI 80035003085 is an OEM arbor nut designed for use in RYOBI lawn mower equipment. The arbor nut secures the cutting blade to the spindle assembly, making it a critical fastener in the blade drive system. Without a properly seated and torque-retained arbor nut, blade integrity and cutting performance are compromised. This is a direct factory replacement part, sourced to original manufacturer specifications. Installation is typically performed by outdoor power equipment technicians or experienced DIYers performing blade replacement or deck service.

This arbor nut is intended for RYOBI lawn mowing equipment where the original 80035003085 fastener is worn, stripped, or lost during blade service. Arbor nut replacement is a routine part of blade maintenance intervals and is commonly addressed during seasonal equipment inspections. The part fits into the blade spindle system and must be matched to the correct spindle thread specification for the target equipment.

Key Features

• OEM replacement part sourced to original RYOBI factory specifications
• Designed for use in the blade spindle and arbor assembly of RYOBI lawn mowers

Compatibility

Designed as an OEM-style replacement arbor nut for RYOBI lawn mowing equipment. Consult the equipment model documentation or RYOBI parts lookup to confirm fitment before installation.

Installation Notes

Disconnect the spark plug wire and allow the engine to cool completely before beginning any blade or deck service. Blade and arbor nut removal typically requires a blade removal tool or breaker bar to counter blade rotation. Follow the equipment manufacturer service documentation for proper fastener torque procedure. This work is within the scope of outdoor power equipment technicians and qualified service personnel.
