description

Forged from alloy steel with induction-hardened cam lobes, it balances torsional strength and wear resistance. The C4.4 is a pushrod engine; the cam lifts tappets, pushrods and rockers to open valves. Its cam profile is calibrated for electronic fuel injection, balancing low-speed digging torque and fuel consumption. It matches 312E,314F,318E,320GC,320F,323F excavators and 420F backhoe loaders, widely used for urban earthworks with frequent start-stop cycles and dusty conditions.

Product Advantages

1. Profile optimized for C4.4 pushrod valve train, delivering steady low-speed digging torque and stable fuel consumption.
2. Precision ground journals maintain consistent oil film and reduce uneven bearing wear under intermittent operation.
3. Balanced hardened layer resists pitting and spalling under repeated impact loads.
4. OEM mounting reference allows reuse of original cam gear and cuts onsite service time.

FAQ 

Q: Does 363-3890 work with 315-3384 tappets?
A: They are matched C4.4 valve-train parts. 363-3890 is camshaft and 315-3384 is tappet. Full set replacement is recommended for overhaul.

Q: How many 363-3890 camshafts are needed for one C4.4 engine?
A: C4.4 is inline 4-cylinder engine, only one camshaft is fitted per engine.

Q: Can lightly worn original cam gear be reused?
A: It is allowed after backlash inspection. Replace the gear if backlash exceeds service limit to prevent accelerated wear.
