Quick coupling 3/8", male 45/910700 is a genuine JCB part for the JCB machines. The card also lists 45/920067.

A quick release coupling lets attachment hoses be connected and disconnected without tools and without losing oil; it consists of a female and a male half. Flat-face couplings lose almost no oil when separated and let no air or dirt into the system when connected. A worn or damaged coupling leaks, is hard to connect or restricts flow in the attachment line. Coupling size and thread are chosen to suit the hose line. The genuine coupling is the standard coupling for JCB attachment lines, with a corrosion-protected body. Its internal valve closes both halves when separated, so the oil stays in both the attachment and the machine when the hoses are disconnected. The coupling is supplied new. The coupling body carries its size and series marks. State the size and the mating half type when ordering.

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.
