Reference data for identifying the Mercedes-Benz OM473 heavy-duty inline-six and its production generations. These values are for engine identification, not part selection — parts should always be selected by OEM number.

Vehicles Using the OM473 Engine
The OM473 15.6 L inline-six is fitted to Mercedes-Benz's heaviest-pulling tractors. The applications below are indicative; VADEN fitment is compatibility-based and must be verified by OEM or chassis number for each vehicle.
Air-suspended heavy-haulage tractor for the heaviest transport tasks, with gross combination weights up to roughly 250 t; the flagship OM473 application.
Actros compatibility hub →Steel-suspended heavy-haulage tractor for construction and off-highway heavy transport, sharing the same OM473 driveline.
Long-haul and heavy-duty tractors that use the 15.6 L for maximum pulling power at low engine speed; the '63' designation denotes the 625 hp class.
Actros compatibility hub →Heavy construction and site-support trucks that draw on the OM473's peak 3,000 Nm of torque.
A 15.6 L heavy-duty six from the same Daimler Heavy-Duty Engine Platform (HDEP), used in Freightliner and Western Star. An engine-family cross-reference, not a Mercedes-Benz Europe model.

Frequently Asked Questions
Do VADEN parts fit OM473-powered vehicles?
Yes. VADEN supplies air-brake compressors plus cooling, brake, engine and fuel-system parts compatible with OM473-powered vehicles such as the Actros SLT, Arocs SLT and top-rated Actros and Arocs. Each reference is listed against the OEM numbers it is compatible with, and fitment should always be verified by OEM number before ordering.
Is the OEM number enough to select the correct part?
The OEM number is the primary way to select the correct part. VADEN catalogues every reference against the OEM numbers it is compatible with, so matching your vehicle's OEM reference to the listing is the reliable method to confirm fitment before ordering.
Which vehicles use the OM473 engine?
The OM473 15.6 L powers Mercedes-Benz's heaviest-haulage tractors — the Actros SLT and Arocs SLT — and the top power ratings of the Actros and Arocs (for example the 2663 and 4163). In North America, the Detroit DD16 is the sibling engine from the same Daimler Heavy-Duty Engine Platform (HDEP).
Which part groups does VADEN offer for the OM473?
Of the 47 catalogued references, 40 sit in the air-brake compressor group — VADEN's core strength. Compatible references are also listed in the cooling-system, brake-system, engine and fuel-system groups. All selections should be verified by OEM number.
Is the OM473 a V6?
No. The OM473 is an inline-six (R6) heavy-duty engine; a 'V6' label seen in some trade write-ups is incorrect, and the official Daimler/Mercedes-Benz release confirms the in-line six-cylinder. Its defining feature versus the smaller OM471 is turbo-compound, which recovers residual exhaust energy back to the crankshaft.
Where can I order OM473-compatible VADEN parts?
Use the OEM-number search or the cross-reference on this page to identify the matching VADEN references, then order through your VADEN distributor or contact VADEN directly. Confirm fitment by OEM number before placing the order.
