Komatsu D51EX-24 Dozer Replacement Parts Final Drive Unit 12Y-27-30100 706-8H

The 12Y-27-30100 and 706-8H-01180 Final Drive units are heavy-duty propulsion mechanisms engineered exclusively for Komatsu D51EX-24 crawler dozers. This rugged assembly couples a hydrostatic travel motor with a heavy-reduction planetary system, delivering the immense pushing power and continuous traction required for aggressive grading and earthmoving operations.

Komatsu mini-excavators are known for their reliability and performance in tight spaces. The final drive is a critical component that withstands constant exposure to demanding conditions. If your machine exhibits tracking issues or reduced climbing capability, the 22H-60-13112 travel motor may require replacement.

Our premium replacement units are manufactured to match Komatsu's specifications, featuring induction-hardened gears and high-load bearings to ensure reliable performance and extended service life.

These Komatsu mini-excavators are utilized globally, and our drives are optimized for various regional conditions:

• North America & Europe: Engineered for rental and utility sectors, providing durability for high-frequency use in urban infrastructure projects
• Southeast Asia & Oceania: Features reinforced floating seals to prevent ingress of abrasive sandy soils and tropical mud
• Japan & East Asia: Tuned to match high-precision control systems for smooth operation

• Compact High-Torque Design: Engineered to fit narrow undercarriage tracks without sacrificing drawbar pull
• Seamless Integration: Fully compatible with Komatsu tracking systems for efficient operation
