Product Description
Cum-mins PT Mechanical Fuel Injector 3406604 for M11 / QSM11 / ISM11 Medium-Duty Diesel Engine
This OEM-grade cum-mins PT fuel injector 3406604 is exclusively designed for cum-mins M11, ISM11 and QSM11 mechanical diesel engines. Adopting advanced precision alloy processing technology, it delivers consistent fuel atomization and accurate fuel metering under full-load heavy-duty operation.

It effectively resolves common injector faults: insufficient engine power, black smoke exhaust, hard cold start, unstable idle speed, high fuel consumption and injector oil leakage. Multi-layer heat-resistant sealing rings prevent oil seepage under long-term high temperature and vibration. Each injector completes strict bench testing for spray pattern, opening pressure, fuel flow and tightness before delivery.

Both brand new and fully reconditioned reman injectors are available in stock. We offer 12-month global warranty, neutral export packaging, flexible MOQ and tiered bulk discount for heavy truck repair shops, machinery service centers & worldwide cum-mins diesel parts wholesalers.

We build a standardized independent calibration workshop equipped with full set dedicated XPI test benches, implementing 100% full performance inspection for all injectors before shipment to maintain consistent stable quality.
Our core competitive advantages: massive ready spot inventory, factory-direct competitive price, low MOQ support, customizable neutral export packaging and global door-to-door logistics delivery solutions.
