MEDIUM FITTING FILTER 30 MICRON 889419

Function and technical context

The 30 micron medium Racor filter (reference 889419 / RAC2040PM-OR) acts as a protective barrier in the fuel supply circuit of Volvo Penta marine diesel engines, intercepting solid particles, sediments and contaminants present in the diesel before they reach the injection pump and injectors. Working with a filtration threshold of 30 microns, it effectively retains impurities that compromise the operation of the precision elements of the injection system, whose tolerances are extremely small. Its characteristic red color facilitates identification in installations with multiple filter assemblies, and its medium size makes it suitable for flow rates typical of medium and large displacement engines in intensive use marine applications. A filter in poor condition or clogged causes pressure drop in the fuel line, progressive loss of power and even unexpected engine stops, with the risk that this entails in navigation.

When to replace this part?

The most common symptoms of a saturated or degraded fuel filter are: difficult cold starting, fluctuations in idle speed, jerks or loss of power under load and increased fuel consumption without apparent cause. For Volvo Penta marine diesel engines in regular use, it is recommended to replace the filter element every 250-500 hours of operation or at least once per boating season, always following the manufacturer's maintenance plan. Replacing the Racor filter preventively at the beginning of each season is the simplest and most economical measure to avoid breakdowns in the injection line, the repair of which can be extremely expensive.
