LN003940 SH130-6 Oil Cooler supports lubrication temperature control for B2B excavator parts repair, engine overhaul, and wholesale sourcing.
The LN003940 SH130-6 Oil Cooler YNF17789 is used in a compatible excavator engine lubrication circuit. Heat generated around bearings, pistons, crankshaft components, and other lubricated surfaces is absorbed by circulating engine oil. The oil cooler is used to transfer part of this heat away so suitable lubrication conditions can be maintained during machine operation.
This component should be distinguished from the excavator’s hydraulic oil cooler. The LN003940 engine oil cooler is associated with the engine lubrication system rather than the main hydraulic working circuit.
For B2B buyers and repair workshops, fitment should be confirmed by the LN003940 reference, SH130-6 machine information, cooler shape, mounting arrangement, fluid passages, sealing surfaces, and existing-part photos. Proper verification is especially useful for international purchasing because similar engine oil coolers may have different installation configurations. Incorrect inventory, repeat freight, and engine-overhaul delays can therefore be reduced.
