  • In order to meet ever increasing market demands, the kohler group has been updating its range of air-cooled, single cylinder diesel engines. Now, we are pleased to present the new kd15 440 engine, which, with its advanced technical features, strengthens and improves the current 15 ld ngine series elevating it to the very top of the class within its power range.

    The 15 ld440 model, already a market leader in numerous sectors including: agriculture, construction, generating sets and pumps, has been substantially updated. Now re-branded as the kd15 440, the new engine has improved performance, reduced maintenance costs and increased ease of use for the operator.

    AIR CLEANER. The new air filter allows an use also in extremely dusty conditions. This result has been achieved thanks to a high efficiency separator with pre-filter (optional) and an ccumulated-dust drain valve in the filter itself. Furthermore, the increased dimensions of the cartridge and the high filtration capacity of the paper element greatly enhances the engine protection, resulting in a considerable reduction in maintenance costs.

    TANK AND FUEL FILTER. The new tank, with its modified components, greatly contributes to facilitating all maintenance operations due to some significant improvements, including a new fuel filter which is enhanced with additional safety filter protection. The primary filter (optional) and the safety one, used in tandem, avoid the accidental entry of foreign particles during the fuel refilling process. The primary filter housed inside the tank is easily accessible and can be replaced without the use of any special tools.

    DRAIN TAP. The new drain tap makes it possible to remove water and impurities which accumulate in the bottom of the tank, allowing for cleaning without the need to dismantle other components.

    TAIR CLEANER CLOGGING INDICATOR (OPTIONAL). The air filter clogging indicator integrated into the engine configuration makes it possible to clearly see when maintenance is required.

    LARGER OIL SUMP (OPTIONAL) The larger oil sump increases the intervals between maintenance to 500 hours as opposed to 250 hours in standard versions.
