Manitou MRT 1840 2012 Parts Catalog

I’ve been turning wrenches for 28 years, and I’ve seen too many guys order the wrong seal kit because they used a third-party parts list. That’s a waste of time and money. The Manitou MRT 1840 2012 Parts Catalog is the factory document – 686 pages of exploded views, part numbers, and cross-referenced diagrams. If you’re working on a telehandler, this is the only source you should trust. It’s not a reprint, not a compilation of guesses. It’s what Manitou shipped to their dealers.

Accessories: Predisposiz.cestello and Radiocomando Kits

Need to add a basket or a radio remote? The catalog breaks down every accessory kit. The section on Radiocomando (726579) and (909530) covers the transmitter, receiver, wiring, and electric accelerator. You’ll find the exact part numbers for the Scatola su braccio (box on arm) and the Cabl.pulsant. e supp. (button wiring and support). If you’re retrofitting a remote control, you don’t want to guess which harness fits – the factory diagram shows it.

Bracci – Complete Arm Assembly Breakdown

The boom on a MRT 1840 is a complex piece of steel and hydraulics. This catalog gives you exploded views of the external arm, the three extension stages (1° sfilo, 2° sfilo, 3° sfilo), and the T.S. (telescopic section). The hydraulic sections are split into Imp.idraul.(alimentaz.) – supply side – and Imp.idraul.(lato braccio) – arm side. Each cylinder – lift, compensation, extension, and rotation – has its own page with seals and rod numbers. No more measuring a seal with a caliper and hoping it fits.

What Torque Specs Are in This Parts Catalog?

Let me be clear: this is a parts catalog, not a service manual. You won’t find torque values for head bolts or bearing preloads here. What you get is every fastener listed with its part number and thread size. Need to replace a bolt on the Riduttore rotaz. (rotation reducer)? The catalog tells you which Manitou bolt to order. For assembly torque, you need the service manual, but for identifying the correct part, this catalog is the only game in town. Check the filter index on page 3 – it lists all filter cartridges across five languages.

Imp. Elettrico: Wiring Harness and Logic Box Diagrams

Electrics on these machines can be a nightmare, especially with the Scatola logica (logic box) and the Arrotolatore braccio (arm cable take-up). The catalog shows the main cabin wiring (5 pages of Cabl.cruscotto princip.), the front and rear chassis harnesses, and the micro-switch locations for the stabilizers. If you’re chasing a no-start or a boom function fault, the wiring diagrams here are schematic – not just a photo of a harness. You can trace the Microinterr. stabilizz. (stabilizer microswitch) circuit back to the logic box.

Transmission: Axle and Hydrostatic Pump Details

The drivetrain section covers the Pompa idrostatica (hydrostatic pump) with its rotor, hydraulic adjustment, gear pump, and limiter. The Motore idrostatico (hydrostatic motor) is broken down next. For the axles, you get both front and rear – Ponte anter.(729957) and Ponte anter.(910278) – each with separate sections for the differential, planetary reduction, brakes, and steering. The LISTA PONTI (axle list) gives you a quick reference. Need a part for the Ingranaggi cambio (transmission gears)? The exploded view shows every gear and shaft. Remember: always use factory parts on these hydrostatic systems – a wrong seal can cost you a whole pump.

Motore NL75003: Engine Component Exploded Views

This section covers the Perkins-derived NL75003 engine. The catalog gives you the Monoblocco (block), Albero-bielle-pistoni (crank, rods, pistons), Testata (cylinder head), and Asse e bilancieri (camshaft and rockers). You’ll also find the injection pump, injectors, water pump, oil cooler, and all the Applicazioni varie (various applications) like the flywheel housing and starter motor. If you need to rebuild the top end, the catalog lists every gasket, valve, and spring. For a more detailed service procedure, see the related Manitou MRT 1840 1998 Parts Catalog – though that one is for an earlier model year, the engine layout is similar. For the exact 2012 engine, you want this catalog.

Who Needs This Parts Catalog?

If you own a Manitou MRT 1840 from 2012, you need this. Shop owners who want to keep their parts room organized – this is the master list. DIY mechanics who do their own repairs – you’ll stop guessing which seal to order. Even beginners can use it to identify parts on a machine that’s new to them. The catalog is in five languages: Italian, French, English, German, Spanish. So if you’re in North America, the English section is there. But the exploded views are universal. I’ve had customers tell me they saved a full day of downtime by looking up the right part number before calling the dealer.

Why Factory OEM Beats Aftermarket

I’ve seen aftermarket parts catalogs that list a single part number for a whole assembly, or worse, they omit the hardware. This is the original Manitou document – published 09/2012, reference 648633. Every page is scanned from the factory print. The Motore idrostatico section shows the exact seal kit, not a generic “rebuild kit.” The Stabilizzatori section lists the pressure switches and their wiring. An aftermarket book would show a generic solenoid. Not here. If you want to avoid the headache of wrong parts, use the factory source. For related machines, check the Manitou MRT 1840 1998 Parts Catalog – Section: Catalogus Reserveonderdelen or the K-D Manitou MVT 1230L MVT1230LC Parts Catalog – 264 Pages if you’re working on a different model. External reference: see this Wikipedia article on diesel engines for understanding the NL75003 engine family, or this Wikipedia article on diesel engines for general background.

Does this manual include torque specifications?

No. This is a parts catalog, not a service manual. It lists part numbers, exploded views, and diagrams. For torque specs, you need the official service manual.

What languages are available?

Italian, French, English, German, and Spanish. The index and part descriptions are in all five languages.

Is this a digital access or a physical book?

Digital access in PDF format. You can search, print, or view on a tablet in the shop.

Can I find the part number for the hydraulic pump on the MRT 1840?

Yes. Look under the section “Imp.idraulico princ.” and then “Pompa imp. idraulico.” The exploded view shows the pump assembly with individual part numbers. The same section covers the manipulators, distributor, and tank. I’ve used it to order a new pump seal kit – the part number matched exactly what the dealer had in stock.

That’s the bottom line. If you’re tired of chasing the wrong part, if you want to keep your machine running without guessing, Access the Factory Manual now. It’s the same document Manitou techs use. No more wasted trips to the parts counter.
