FAQ

Q1: What is the difference between the K49, K16, K28, and K48 models?

A: These model numbers typically refer to the specific design and pressure setting of the delivery valve. While physically similar, the internal spring tension and orifice size may vary to match different injection pump calibrations. The K49 is the primary model; the others are compatible alternatives. Always confirm your pump’s specific requirements.

Q2: How do I install this delivery valve?

A: Installation should be performed by a qualified diesel technician. The valve is typically located at the outlet of the injection pump. The process involves removing the old valve, cleaning the seating area, and installing the new valve with a new sealing gasket to the correct torque specification. Incorrect installation can lead to fuel leaks or poor engine performance.

Q3: What are the signs of a failing delivery valve?

A: Common symptoms include hard starting, rough idling, black smoke from the exhaust, reduced engine power, and poor fuel economy. A faulty delivery valve can cause fuel pressure to drop in the line between the pump and injector, leading to inconsistent injection.
