Starter Motor, Compatible with YANMAR 4TNE98 4TNV98, 24V 9T 119131-77010 119131-77011, Standard Replacement Parts for Excavator Power Systems

Engineered for heavy-duty construction and mining excavator operation scenarios, this starter motor is manufactured to factory standard specifications, delivering reliable cranking performance for excavator power systems even under extreme low-temperature and high-dust working conditions. The 9T gear structure is made of high-strength alloy steel, with excellent wear resistance and impact resistance, ensuring stable engagement with the flywheel during each start-up process. The 24V winding component uses high-temperature resistant insulating material, effectively reducing heat accumulation during long-term operation and extending the service life of the whole assembly. It can directly replace the original damaged starter, eliminating complex modification steps, and is suitable for frequent start-stop working cycles of heavy construction equipment. The fully sealed housing design realizes physical interception of external dust and debris, maintaining stable operation performance in harsh construction site environments.

• 24V rated voltage design, matching the electrical system parameters of compatible excavator models, providing strong and stable cranking power to support normal start-up of equipment in low-temperature environments
• 9T alloy steel gear with precision machining process, ensuring smooth and accurate engagement with the engine flywheel, minimizing gear wear and abnormal noise during start-up
• Manufactured in strict accordance with standardized specifications, the installation holes and wiring interfaces are fully consistent with the original assembly dimensions, achieving direct replacement without additional modification
• High-temperature resistant copper winding and sealed housing structure, physically blocking construction site dust and moisture from entering the internal components, adapting to long-term harsh operation conditions
• Undergo strict load and durability tests before leaving the factory, ensuring consistent performance that meets factory standard requirements for heavy equipment operation
• Verification: Please check your machine model and part number before purchasing. If unsure, send us your brand and old part photos for confirmation.
