Description
Overview:
The Reinforcement Knob 28463-Z4M-003 is a Genuine Honda part for GX series petrol engines, including GX120UT2 and GX160UT2. Made from a hard‐wearing black polymer engineered to withstand vibration, oil, and fuel exposure, it helps maintain the integrity of the control or starter interface where a knob or grip is subject to frequent handling. Replacing a worn reinforcement prevents play, cracking, or premature wear at the mounting point, supporting smooth and consistent engine operation. It is a direct-fit maintenance part designed for Honda general-purpose engines commonly used in construction, landscaping, and horticultural machinery. Being an OEM component, it matches the original dimensions and finish for a neat, reliable fit without modification.
