Caterpillar (CAT) Marine Engine Spare Parts — OEM & Aftermarket

Banomad B.V. is an independent marine spare parts supplier delivering OEM and quality aftermarket parts for Caterpillar marine propulsion and auxiliary / generator-set engines — from the 3500-series workhorses on tugs, OSVs and workboats to the large-bore 3600-series main engines and the C-series high-output units. We work directly with manufacturers and primary stockists — no middlemen — so ship owners, operators and technical superintendents can source the right part fast, with compatibility confirmed against engine model, arrangement and serial number.

Frequently asked questions

Do you cover the 3500, 3600 and C-series engines?

Yes. We source parts across the 3500 and 3600 series and the C-series (C7.1 to C280), for both propulsion and generator-set configurations.

Can you supply overhaul / inframe kits and turbochargers?

Yes. Complete overhaul and inframe kits, turbochargers and wear-item packages are a regular part of what we supply.

I don’t have the part number — can you still quote?

Yes. CAT parts can be identified from the engine arrangement number, serial number or a component description; a model-plate photo also helps.

Do you ship worldwide?

Yes. We deliver to ports and yards worldwide under flexible Incoterms.
