Product Number: 40123002
The Highway Automotive 40123002 (KM5044) is a replacement air conditioning condenser designed for Komatsu construction plant, supplying seven confirmed applications across the PC and D and WA and WD series lines. Built to restore cooling system performance on heavy plant machinery, this condenser is a direct-fit replacement for worn or damaged original-equipment units. Constructed from aluminium-to-aluminium (A/A) core material, the 40123002 delivers the thermal exchange characteristics required by demanding construction environments. Aluminium construction offers a strong combination of heat dissipation, corrosion resistance, and manageable weight — important qualities in plant machinery subjected to sustained operational loads. At 520 x 366 x 16 mm (H x W x D), this condenser is dimensioned to suit the original fitment envelope across confirmed Komatsu applications. Verified fits include the Komatsu PC130, PC300, PC350, D175, D375, WA600, and WD600 — covering excavators, dozers, and wheel loaders across the Komatsu range. OE cross-reference 2089797520 allows straightforward identification against original Komatsu parts documentation. Every fitment listed is checked against manufacturer data and backed by the PartsForMachines Fit Guarantee. If this condenser is not the correct fit for your machine, hassle-free returns apply. Confirm your exact model and variant using the selection widget or by searching the cross-referenced catalogue before ordering.
