Installation and First Start

1. Flush the cooling system and replace the radiator cap before fitting the new unit.
2. Match the flywheel housing to the bell housing dry, without forcing bolts.
3. Prime the fuel circuit with the hand pump until resistance is felt before cranking.
4. Run 20 minutes at low idle, then re-torque mounts and check for chafed harness runs.
5. Log the first oil and filter change at 50 hours, then move to the standard interval.

Packing and Transport

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.

Frequently Asked Questions

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.
