Cummins QSK50 Engine for Komatsu 730E

Engine supply for the Komatsu 730E

When a haul truck is parked waiting for an engine, every shift costs tonnes. We help you find a replacement engine from stock in China, check it against your truck before you commit, and organise export packing and shipping to your port.

Komatsu trucks and excavators are a common sight in copper and gold mines across Africa and South America, and engine availability often decides how quickly a machine gets back to production.

Fitment note: Later 730E builds (730E-7) use the QSK50, while earlier 730E-6 trucks use the KTTA50.

What we can supply

• Complete Cummins QSK50 / KTTA50 engine assemblies for the Komatsu 730E, subject to current stock
• Engine parts and overhaul components for the QSK50 / KTTA50
• Modification and installation support when the engine build differs from the original
• Test-bed run and video before shipment, on request
• Export crating, loading and shipping documents
