MAN 26.372 DFAEX (10 Ton)

The MAN 26.372 DFAEX (10 Ton) is a purpose-built 6×6 all-wheel-drive military tipper from the F90 series, with a 26-tonne GVW and 10-tonne payload capacity, powered by the 370 DIN-HP (272 kW) MAN D2866 LF05 diesel engine. Its DFAEX designation defines the complete operational specification: forward-control cab (F), permanent/selectable all-wheel drive with two-speed transfer case (A), single 14.00R20 military tyres on every axle position (E), and tipper body (X), delivering the highest off-road mobility in the 26.372 family.

The 26.372 DFAEX: When the Body Code Tells the Whole Operational Story

Every letter in the MAN F90 body designation carries precise technical meaning — and for the DFAEX, those five letters together describe a vehicle specification that differs in operationally significant ways from every other variant in the 26.372 family. Understanding the code is the starting point for understanding the vehicle, and for understanding why its parts supply requires a different approach.

D — Diesel: Direct injection diesel powerplant — the MAN D2866 LF05 in this application.

F — Fahrerhaus: Standard forward-control cab, with the engine mounted beneath the cab floor in the characteristic F90 short-nose arrangement that MAN carried through this generation.

A — Allradantrieb: All-wheel drive — all three axles driven, 6×6 configuration, with a two-speed transfer case distributing torque across the full drivetrain. This is not an optional engagement; the DFAEX is a full-time or selectable all-wheel drive platform depending on transfer case engagement mode.

E — Einzelbereifung: Single tyres on all axle positions — the defining characteristic that separates the DFAEX from the standard DFAS tipper variant. Where the DFAS runs twin rear tyres (Zwillingsbereifung) on the tandem rear bogie in standard commercial truck fashion, the DFAEX runs a single wide-section military tyre on every wheel position: 14.00R20 throughout. This is not a commercial tyre size — it is a dedicated military cross-country tyre specification, the same 20-inch rim NATO-standard tyre family used across European armed forces' heavy truck fleets of this generation.

X — Kipper (Tipper): The vehicle carries a tipper body — typically a three-way (Dreiseitenkipper) or rear-tip configuration — making the DFAEX a bulk material transport and discharge vehicle in its primary application.

Read together, the DFAEX describes the highest-mobility configuration of the F90 26.372 family: a 6×6 all-wheel drive tipper on large-section single military tyres, built specifically for operating on the unprepared surfaces, soft terrain, and off-road routes that define military engineering and forward logistics environments. It is not a commercial construction truck with military paint. It is a purpose-configured military-specification vehicle whose parts profile reflects that intent throughout.

The Operational Significance of Single Military Tyres

The choice of Einzelbereifung — single tyres — over the Zwillingsbereifung twin-tyre arrangement of commercial tipper variants is the most operationally consequential engineering decision in the DFAEX specification, and the one that most directly affects its parts supply requirements.

On a standard commercial 6×4 or 6×6 tipper, the tandem rear bogie runs twin tyres on each side — two tyres per hub, four per axle, eight across the bogie. This arrangement distributes the axle load across a wider contact patch, which is beneficial on tarmac and hard-packed surfaces where maximum load per unit area is the constraint. But on soft ground — saturated soil, sand, snow, mud, and the unprepared terrain that combat engineering and forward logistics operations routinely demand — twin tyres present a different problem: a narrow combined footprint that cuts into the surface and reduces effective traction.

The 14.00R20 single military tyre runs a significantly wider individual tread than a commercial twin-tyre arrangement. Each tyre presents a broader, more uniform contact patch that distributes load across a larger surface area on soft terrain, reducing ground pressure and improving traction precisely in the conditions where the DFAEX is expected to operate. The 20-inch rim diameter — common across NATO heavy truck fleets including the MAN KAT1 family — means that tyre supply for this vehicle draws from a well-established NATO logistics infrastructure rather than a commercial retail market.

For parts procurement, Einzelbereifung at the rear means that the hub assemblies, bearings, brake drums, and wheel hardware on the rear tandem bogie are dimensioned and rated for single-tyre loading — not for the load-sharing arrangement of a twin-tyre hub. These are different components from their twin-tyre equivalents, and they must be sourced accordingly. AB Defence identifies rear hub configuration from chassis documentation before supplying any rear axle wheel-end component for the 26.372 DFAEX, and does not cross-source from twin-tyre specifications.

Technical Specifications

The ZF 16S-150: A Transmission Matched to the Mission

The ZF 16S-150 — confirmed as the transmission specification on the MAN 26.372 DFAE family by Danish Army vehicle documentation — is a heavier-rated member of the ZF 16-speed manual family than the ZF 16S-130 found on earlier or lower-output F90 applications. The "150" rating in the ZF designation refers to the transmission's input torque capacity in daN·m — a higher rating than the 16S-130, matched to the D2866 LF05's torque output and the 6×6 drivetrain's operating demands.

This rating difference matters directly for parts procurement. The ZF 16S-150 and ZF 16S-130 are not internally interchangeable at the synchroniser ring, gear, and bearing level despite sharing the same family architecture. Sourcing internal gearbox components from a 16S-130 parts list for a 16S-150 gearbox is a specification error — one that AB Defence eliminates by reading the gearbox identification plate before recommending any internal transmission component. Customers submitting the gearbox plate number with their enquiry receive correctly rated internal components as standard practice.

The two-speed transfer case — the additional powertrain element that the DFAEX's 6×6 configuration requires and that is absent from the 6×4 26.372 variants — multiplies the gearbox's already wide range further, giving the driver a low-range gear set for maximum traction in soft terrain and steep gradient conditions. The transfer case engagement mechanism, its internal gearing, input and output seals, and engagement actuators are components specific to the 6×6 drivetrain that AB Defence covers fully and separately from the main gearbox parts list.

Where the DFAEX Operates: The Mission Environment That Defines Its Parts Profile

The MAN 26.372 DFAEX was not designed for tarmac logistics or commercial quarry work. Its entire specification — 6×6 all-wheel drive, single military tyres, 24-volt electrical system, differential locks on all axles, and 400-litre fuel capacity for approximately 450 km range — reflects a vehicle built to operate in forward military areas where road infrastructure cannot be assumed and where vehicle recovery capability must be built into the fleet rather than called from a roadside service.

In combat engineering support, the DFAEX tipper has carried bulk construction materials — aggregate, sand, hardcore, crushed stone — for field fortification, airfield strip construction, and forward operating base infrastructure work where the delivery route is as likely to be a track across saturated ground as a metalled road. The 6×6 drive with differential locks engaged allows the vehicle to maintain forward progress in conditions that would ground a 6×4, and the large-section 14.00R20 single tyres provide the traction surface that soft terrain demands.

In forward logistics roles, the tipper body configuration has served for bulk delivery of aggregates, fuel drums in loose-load arrangement, and engineering stores that can be discharged by tipping rather than requiring manual offloading. The 400-litre fuel capacity — substantially larger than a typical commercial tipper — extends the vehicle's independent operational range, reducing the frequency of refuelling halts in areas where fuel logistics are constrained.

In ammunition and engineering stores transport, the tipper chassis — with its robust sub-frame and hydraulic tipping system — provides structural rigidity under the shock loads that rough terrain imposes on a laden vehicle, loads that would accelerate fatigue in a less robustly engineered platform.

This operating environment has direct maintenance implications. Differential lock components, transfer case internal seals, 14.00R20 wheel-end hardware, and tipper hydraulic system seals are all higher-cycle-count wear items on the DFAEX than on a commercial construction tipper. AB Defence maintains priority stock of these components with the understanding that a DFAEX fleet's highest-demand parts reflect its operational profile, not the theoretical wear rates of a commercial vehicle operated on prepared surfaces.

How the DFAEX Sits Within AB Defence's MAN F90 Specialism

The MAN 26.372 DFAEX is the most mission-specific and most mechanically complex variant in the 26.372 family — and it is the natural culmination of the MAN F90 specialism that AB Defence has built across the 16.220, 16.210, 16.270, 26.281, 26.372, and 33.372. Each of these platforms has deepened our technical knowledge of the D2566 and D2866 engine families, the ZF 16-speed transmission range, and the MAN F90 chassis architecture. The DFAEX adds to this foundation the 6×6 transfer case, the Einzelbereifung wheel-end configuration, the all-axle differential lock system, and the military electrical specification — layers of additional complexity that require the same systematic technical discipline that we apply across the entire range.

For procurement officers managing fleets that include both the standard 26.372 and the DFAEX variant, the critical distinction is this: the DFAEX and the 26.372 DFAS share the D2866 LF05 engine and the ZF 16S-series transmission family — but the transfer case, rear hub assemblies, differential lock components, tyre and wheel hardware, and electrical system are all DFAEX-specific. AB Defence maintains separate parts identification for the DFAEX versus standard 26.372 configurations and resolves every enquiry to the correct variant before supply.

Critical Procurement Distinctions: The DFAEX vs Other 26.372 Variants

AB Defence applies three non-negotiable technical distinctions when processing MAN 26.372 DFAEX parts enquiries — distinctions that protect against the most common mis-ordering errors across the 26.372 variant family.

Transmission rating: The ZF 16S-150 of the DFAEX differs internally from the ZF 16S-130 fitted to other F90 applications. Gearbox plate confirmation is required before internal components are recommended. AB Defence does not supply 16S-130 internal components against a 16S-150 gearbox.

Wheel-end specification: The Einzelbereifung hub assemblies, brake drums, and bearings of the DFAEX rear axle are dimensioned and rated for single-tyre loading. They must not be sourced from commercial twin-tyre specifications. AB Defence confirms the Einzelbereifung configuration from chassis documentation before supplying any rear axle wheel-end component.

Transfer case coverage: The DFAEX's two-speed transfer case has no equivalent on any 6×4 variant in the F90 range. Its internal components, engagement actuators, and seals are DFAEX-specific. AB Defence covers these as a dedicated parts set, separate from the main gearbox parts identification.

Frequently Asked Questions — MAN 26.372 DFAEX Spare Parts

What does DFAEX mean in MAN's F90 designation system? D = Diesel, F = Fahrerhaus (standard cab), A = Allradantrieb (6×6 all-wheel drive), E = Einzelbereifung (single tyres on all positions), X = Kipper (tipper body). Together, DFAEX designates a 6×6 all-wheel drive tipper with single military tyres throughout — the highest-mobility tipper configuration in the F90 26-tonne range.

What tyre size does the DFAEX use? 14.00R20 — a large-section single military tyre on 20-inch NATO-standard rims, fitted to all six wheel positions. This is not a commercial tyre size and cannot be substituted with commercial twin-tyre alternatives.

What transmission is fitted to the 26.372 DFAEX? The ZF 16S-150 — a higher-torque-rated variant of the ZF 16-speed manual family than the 16S-130 used on lower-output or lighter-duty F90 applications. The two-speed transfer case is an additional powertrain unit specific to the 6×6 drivetrain.

Are ZF 16S-130 internal parts interchangeable with the ZF 16S-150? No. The 150-rating designation denotes an internally different specification at the gear, synchroniser ring, and bearing level. AB Defence confirms transmission identity from the gearbox plate before supplying any internal gearbox component.

Does AB Defence supply transfer case components separately from the main gearbox? Yes. The two-speed transfer case is treated as a separate assembly with its own parts identification, including internal gearing, engagement actuators, seals, and mounting hardware. It is not referenced against the main gearbox parts list.

How does AB Defence differentiate the DFAEX rear-axle parts from those of twin-tyre 26.372 variants? The Einzelbereifung hub, bearing, and brake drum assemblies are identified from chassis plate and axle documentation at the enquiry stage. AB Defence does not assume twin-tyre specifications for any 26.372 DFAEX rear-end enquiry.

What information is required for a 26.372 DFAEX parts enquiry? Chassis plate number, engine number, production year, gearbox plate number, transfer case type where known, confirmation of Einzelbereifung configuration, tipper body type (rear-tip or three-way), parts required by description or MAN part number, quantities, delivery destination, and urgency.
