Fuel pre-filter (water separator) 32/925760 JCB, genuine

For the JCB machines: fuel pre-filter (water separator) 32/925760, a genuine JCB part.

The fuel pre-filter (water separator) traps water and coarse particles in the fuel from the tank before the main filter. Water in diesel fuel corrodes and wears the injection pump and injectors, and the pre-filter collects it in a clear bowl or cup at the bottom of its body. The collected water is drained regularly through the drain plug. The pre-filter's job is to extend main filter life and protect the fuel system from water, and a blocked pre-filter causes loss of power and hard starting.

Specifications

Compatibility

According to sources, number 32/925760 is superseded by 320/A7125; the element appears on JCB JS115-JS460 excavators, 85Z, 86C, 90Z and 100C mini excavators and 3CX backhoe loaders. The catalogue also has the aftermarket version (option 1) and aftermarket version (option 2) of this part. Other parts are in Genuine JCB filters.

Fitting

Before the change, stop the engine and clean around the filter. Remove the old filter and wipe the seal face of the filter head. Lightly lubricate the new filter's seal with clean fuel, screw the filter on by hand and, once the seal touches, tighten it by the amount the maker specifies; overtightening with a wrench crushes the seal and makes removal hard. Then bleed the fuel system with the hand primer or the method in the manual, start the engine and check for leaks. After changing the pre-filter, check the water bowl and drain plug for leaks, and renew a cracked bowl, since air drawn in through the crack makes the engine hard to start.
