Charge air cooler top hose 332/F8503 is an aftermarket part for the JCB AWS backhoe loaders (Tier 3).

In the JCB catalogue, 332/F8503 is the top hose of the charge air cooler (CAC, intercooler) for AWS machines with Tier 3 engines. Hot compressed air from the turbocharger is cooled in the intercooler and passed to the intake manifold; cooler air is denser, so the engine works more efficiently. This line is under pressure: a cracked hose or loose clamp leaks charge air and causes power loss, black smoke and high fuel consumption. The photo shows thin connecting hoses together with the main hose. Renew the clamps when the hose is changed and push the ends fully home. After the change, run the engine under load and check the joints for leaks. The hose is chosen by part number and compared with the old one for shape. Oil traces in the intercooler line can mean the turbocharger needs checking. The hose is made to withstand the temperature and pressure of the charge air.

JCB 3CX and 4CX hydraulic circuit diagrams by build year, with component keys
There is no single hydraulic circuit for the JCB 3CX and 4CX backhoe loader: it depends on the build year and the pump type. Section E of the JCB service manual (publication 9803/3290-14) gives separate circuits for the gear pump 3CX built before and after September 2007, for the variable flow 4CX (7-spool and 6-spool), and for the 3C-14 (214e) and 3C machines. Below you will find the circuits themselves, the component keys and some notes on tracing the oil flow through a circuit.

JCB 3CX / 4CX Hydraulic Pressure: Settings, Pressure Testing and Causes of Low Pressure
On JCB 3CX and 4CX backhoe loaders with a gear pump, the working pressure of the hydraulic system is limited by the main relief valve in the loader valve: 236–241 bar on machines up to serial number 964124 and 248–252 bar on machines from serial number 964125 (standard and high-pressure hydraulics). It is checked with a 0–400 bar pressure gauge connected to the loader valve test point, with the engine at 1500 rev/min and the oil warmed to 50 °C. Below are the settings, the test procedure and the reasons why pressure drops, taken from the JCB service manual (Section E).

JCB 3CX / 4CX Hydraulics: Circuit Diagrams, Pumps and Relief Valve Pressures
Section E of the JCB service manual (publication 9803/3290-14) deals with the hydraulic system of the JCB 3C, 3CX and 4CX backhoe loaders. It brings together technical data for the pumps and valve blocks, hydraulic circuits for machines of different build years, valve operation, fault finding tables, and the procedures for pressure testing and for overhauling the pump, valves and rams. The section PDF runs to 302 pages.
