Engines
Complete EMD 645 and 710 and ALCO 251 engines and long blocks for locomotive, marine and power generation use: remanufactured by rebuilders we audit, or serviceable and inspected, outright or on exchange. Model, cylinder count and rating confirmed from your nameplate before quoting.
What a remanufactured engine includes
- Crankcase cleaned, crack inspected and repaired; crankshaft inspected, ground or replaced; new main and rod bearings.
- New or remanufactured power assemblies, camshafts and gear train components to OEM clearances.
- Lubricating oil, cooling and fuel systems rebuilt; injectors and governor calibrated; turbocharger remanufactured or replaced.
- Dynamometer or load test where the rebuilder has a cell, with the test report supplied; engine preserved and crated for the route.
When a complete engine makes sense. The crankcase is cracked, the fleet cannot spare the locomotive for a shop rebuild, a marine or power installation must be back on line within weeks, or the OEM lead time runs past the tender deadline. A remanufactured exchange engine is quoted with the core terms so the old engine still has a value.

Delivery and core return
Cradled, sealed and shipped on your Incoterm; core return instructions and packing for the returned unit are included when the deal is exchange.
You buy the unit and keep your old one. Best when the core is scrap, when the fleet is being expanded, or when the return freight costs more than the core credit is worth.
You receive a remanufactured unit and return your core within an agreed window, usually 60 to 90 days. The core credit is stated on the quotation and depends on the core being complete and rebuildable; we tell you what counts as rebuildable before you commit.
Your own unit is rebuilt and comes back to you. Longer lead time, lower cost, and the right choice for unusual models where exchange stock does not exist. We manage the shipping both ways and report progress weekly.

7FDL engines are quoted per enquiry. Send the nameplate and the locomotive class; we confirm availability and lead time.

Exchange units from stock, eight to sixteen weeks to departure depending on model and rating; serviceable units and long blocks are quoted per unit.
- How do I know a remanufactured unit will fit my locomotive?
Send the nameplate and the locomotive class. We confirm the model, the interchange and any application notes before the quotation, and the quotation names the exact model supplied.
- What documents come with a complete unit?
The rebuilder's test report, our receiving inspection photographs, a certificate of conformance, the warranty statement and the export documents. Material certificates are supplied for new parts fitted where your tender asks for them.
