TUELETFU Steering Gear Kit for John Deere D125 D130 D140 D150 D160 — Direct-Fit Sector & Pinion with Bushings

The TUELETFU Steering Gear Kit is a direct-fit replacement steering sector plate and pinion assembly designed to restore steering control on John Deere D100-series lawn tractors.

If your John Deere D100–D170 series mower feels loose, binds, or has play in the steering, this kit provides the core mechanical parts to rebuild the steering gear. The set includes a steering sector gear plate, pinion gear, metal and plastic shaft bushings, plus the mounting bolt and nut to simplify installation. All components are made to resist corrosion and match the factory mounting points so you can return the mower to predictable handling without replacing the entire steering box.

How will this kit affect steering performance?

Replacing worn sector and pinion components removes slack and harsh spots in the steering mechanism. You should notice firmer, more consistent steering input and reduced wobble or wandering during operation. It refines the mechanical connection between the steering wheel and front end so directional control becomes more precise.

• Direct-fit sector plate and matching pinion gear for D100-series tractors
• Metal and plastic bushings restore correct shaft alignment and reduce play
• High-corrosion-resistance materials prolong service life
• Includes bolt and nut for straightforward reassembly

Which mower models does this steering gear kit fit?

This kit is made for a range of John Deere riding mower models in the D100 through D170 families. It matches the common sector-and-pinion layout used on these units, but you should always compare the pictured parts to your existing components to confirm fit. The kit is most often used on D100, D105, D110, D120, D125, D130, D140, D150, D160 and D170 machines.

What parts are included and what materials are used?

The package contains the steering sector gear plate, a pinion gear, two types of shaft bushings (plastic and metal), and a bolt with a nut for mounting. The components are produced from durable materials chosen for strength and rust resistance so they hold up to wheel loads and outdoor exposure. Having both plastic and metal bushings lets you replace worn guides and tune shaft fit.

• 1 steering sector gear plate and 1 pinion gear
• 2 plastic and 2 metal steering shaft bushings for proper clearance
• 1 pair of bolt and nut for mounting the assembly
• Corrosion-resistant finishes on metal parts

How difficult is installation and what should I check before buying?

Installation is moderate difficulty: basic hand tools and common mechanical skills are usually sufficient. Before ordering, visually compare this kit’s configuration to your damaged steering components and check that mounting holes and shaft diameters match. If you’re not comfortable with steering work, consider a professional install to ensure safety and correct alignment.

• Requires basic tools and mechanical experience
• Compare photos to your worn parts for correct fitment
• Follow torque specs and alignment steps from mower manual
• Consider professional help if unsure about steering reassembly
