YNF16957 193-2749 Diesel Injector for CAT 311C 320C Engine Repair

The 193-2749 CAT 320C Fuel Injector YNF16957 is supplied for compatible excavator engine fuel system repair and replacement applications. Fuel is delivered into the combustion chamber in a controlled manner so that stable diesel combustion, engine response, and working performance can be supported.

The product may also be identified by reference number 5I-7706, providing B2B buyers with an additional number when injector replacement requirements are being compared. Precision internal components are used to support dependable fuel injection under continuous construction equipment operating conditions.

For excavator parts distributors and repair workshops, injector matching should be completed before bulk purchasing. The part number, machine model, existing injector markings, body design, and removed-part photos can be compared before an order is confirmed. This helps reduce incorrect purchases, repair delays, unnecessary international freight costs, and slow-moving inventory.
