The engine travels on a bolted steel base inside a plywood case. We photograph the loading process and share the images with the bill of lading so you can see exactly how the unit left our yard.
Can I keep my existing hydraulic pump? In most cases yes. Send the pump model and we will confirm the spline and pilot bore before shipment.
Is the harness plug-and-play? The harness matches the 220HP electronic calibration. If your machine uses an older mechanical throttle, we supply the conversion bracket at no extra cost.
What is the production lead time? Stock units leave in 3 to 5 working days. Built-to-order configurations take 15 to 20 days.
Are wear parts available later? Yes. Pistons, liners, bearings, gasket sets and injectors are kept in stock for the full service life of the engine.
Tell us the machine model and the duty cycle, and we will come back with the correct rating, mounting kit and a delivered price. Spare parts can be consolidated into the same shipment so you are not paying freight twice.
