Steer Knuckle Seal for Kubota

This steer knuckle seal, referencing OEM cross-reference numbers TC010-99600 and 3021-0017, is a replacement component designed to prevent fluid leakage and contaminant ingress in the front axle steering knuckle of compact tractors. This steer knuckle seal serves as a direct-fit sealing solution for select Kubota tractor models, ensuring reliable operation of the steering linkage. It is a critical wear item for maintaining proper lubrication and excluding dirt and debris from the knuckle assembly.

Overview

This steer knuckle seal for Kubota tractors is a precision-molded rubber seal that fits into the steering knuckle housing to keep grease in and debris out. It is designed for use on compact utility tractors, particularly the Kubota L-series models that use the TC010-99600 or 3021-0017 part reference. Replacing a worn steer knuckle seal helps prevent premature wear of kingpin bearings and bushings.

Good To Know

Q: How do I know this seal fits my tractor? A: This seal is designed for Kubota L2501, L2800, and L3400 models using the TC010-99600 or 3021-0017 cross-reference, but always verify your specific serial number before ordering.

Q: What happens if I do not replace a worn knuckle seal? A: A worn seal allows dirt and moisture into the knuckle bearing area, leading to accelerated wear of pins and bushings, plus fluid loss.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
