Product Brief

Model 4921431 belongs to the mature CCR1600 CAPS II common rail fuel system, specially calibrated for medium-displacement Cum-mins 8.3L & 8.9L diesel power units. Unlike HEUI hydraulic pumps for CAT heavy excavators, this electronically controlled common rail pump integrates pressure adjustment and fuel metering modules, balancing power output and fuel economy for buses and medium trucks that run frequent start-stop and long highway cruising. Every casting, plunger and solenoid valve strictly follows OEM dimensional standards for direct bolt-on swap without any engine bracket modification.
