Frequently Asked Questions (FAQ)
1. Are your parts genuine Scania or aftermarket?
We offer options to fit your budget and technical requirements: Genuine OEM Scania parts, Original Equipment Manufacturer (OEM) equivalents, and high-quality aftermarket parts built strictly to international marine classification standards.
2. How do I know if a part fits my Scania DI12 44M or 59M engine?
While many core internal components (like crankshafts, main bearings, and connecting rods) are interchangeable across the Scania 12-litre platform, specific marine configurations like the continuous-duty 44M or high-output 59M use completely different turbochargers, cooling layouts, or fuel settings. Always check your engine serial number plate and contact us for verification.
3. Do you supply complete engine rebuild kits (in-frame/out-of-frame)?
Absolutely. We configure tailored overhaul kits for the entire Scania DI12M and related sub-models. These kits include pistons, pins, wet liners, rings, main and rod bearings, and all necessary seals and O-rings for a complete block rebuild.
4. How quickly can you ship Scania 12-litre parts worldwide?
We offer global express freight shipping. Depending on your location and whether the parts are currently on our warehouse shelves, global transport to major maritime hubs, shipyards, or ports typically takes between 2 to 5 business days.
