Fan cowl (diffuser) 123/05898 JCB 3CX/4CX, aftermarket

Fan cowl (diffuser) 123/05898 is an aftermarket part for the JCB 3CX and 4CX backhoe loaders.

The fan cowl (diffuser) surrounds the fan so that air is drawn through the radiator core. If the cowl is broken or missing, the fan pulls air around it, flow through the radiator falls and the engine runs hot, especially under heavy load. Broken pieces can also hit the fan and damage the blades. The cowl also closes off the spinning fan and protects hands and tools during servicing. Running for long with a broken cowl means air passes through only part of the radiator and the core clogs unevenly. The machine should not be run without the cowl, especially in summer and in heavy digging work. The cowl is plastic and fixes to the radiator at its mounting points. The cowl is supplied new. The part number defines the cowl shape.
