Kubota Steering Shaft Repair Kit

This steering shaft repair kit is engineered for the regeneration of the steering column on Kubota B-Series compact utility tractors. The kit addresses wear in the steering gear assembly, restoring precise steering response and eliminating excess play. The kit typically includes high-load needle bearings, oil seals, thrust washers, bushings, and a ball nut assembly matched to the OEM steering shaft specifications. It is designed to service the steering shaft assembly referenced by Kubota OEM part number 66811-41200, which features a 475 mm length, 14 mm x 18 spline interface, and 12 mm thread. Application covers gear-drive models across the B4200, B5100, B6000, B6100, and B7100 series, encompassing both two-cylinder (D650) and three-cylinder (D750-A) diesel engine configurations. Installation requires standard hand tools and steering gear disassembly. Regular overhaul prevents catastrophic steering failure and reduces operator fatigue.
