advantages

Integral precision forging ensures high rigidity and stable meshing clearance.
High-precision internal grinding, uniform tooth profile, low noise and high transmission efficiency.
High surface hardness and strong wear resistance, suitable for long-term heavy-load meshing.
Good fatigue resistance, not easy to crack or deform under strong vibration and impact.
Standard positioning flange design for easy installation and high concentricity.
Original genuine part with strict size matching, effectively avoiding abnormal wear.

maintenance & replacement tips

Check tooth surface wear, pitting, cracks and deformation during overhaul.
Keep the gear cavity clean and sufficient lubricating oil to reduce abrasion.
Assemble with specified interference and torque to ensure stable positioning.
Avoid overload and sudden impact to prevent gear tooth damage.
Use original 275000791 inner gear ring assembly to ensure transmission stability.
