Excavator Valve
Precision Control (Servo) (continued) JCB 3CX, 4CX, 214e, 214, 215, 217
(Machines from January 2003)
In the interest of machine efficiency and consistent backhoe operation the excavator valve is of a closed centre design and incorporates pressure compensating valves F, for each service.

These features enable the valve to operate as follows:
No service selected (all spools in neutral) Oil from the loader valve high pressure carry over enters the excavator valve at the inlet port A. Oil flows across the flushing valve spool assembly B and returns to tank from the outlet port C.

Servo Spool Actuation
When a service is operated servo pressure from the joystick control valve acts on the end of the relevant service spool D- and displaces the spool proportionally against the force of
the centering spring E, allowing the oil to flow to move the required service. When the servo pressure on the end of the service spool is reduced the force of the centering spring overcomes the servo pressure and the service spool will move back proportionaly to the central neutral position.

The JCB 444 engine is a 4 cylinder diesel engine in which the fuel is ignited by compression ignition (C.I.). The engine operates on a four stroke cycle,
=> The Four Stroke Cycle (4-14).
The engine is started by electric starter motor
7-1. The motor turns the engine via a pinion and teeth on the engine flywheel
7-2. When the engine runs the crankshaft
7-3 drives the camshaft
7-4 via gears. The camshaft opens and closes the inlet and exhaust valves
7-5 and 7-6 via push rods
7-7 in time with the four stroke cycle. The engine has 16 valves, 2 inlet and 2 exhaust valves for each cylinder.
The crankshaft also drives a mechanical fuel injection pump
7-8 via gears. The pump injects fuel via injectors, or atomizers
7-9 into each cylinder in time with the four stroke cycle. Fuel is pumped from a fuel tank to the injection pump by means of a lift pump
7-10 driven by cam lobes on the camshaft.
