Manitou M SERIES E2, MRT2150 2003 Parts Catalog

I’m Mike Callahan. 28 years turning wrenches in San Antonio, and I’ve seen more shops lose money because some tech grabbed a generic parts diagram off the internet instead of the real factory book. If you’re working on a Manitou M SERIES E2, MRT2150 2003 Parts Catalog, you don’t need a reprint that lumps all serial numbers together. You need the book that tells you which axle reduction gear goes with which serial number range. That’s this 708-page factory catalog.

708 Pages of Serial Number-Specific Data

From the alphabetical contents on page 3, you can see why this catalog matters. The front axle housing alone has three separate entries depending on the axle serial number: B–ITA – 757628 & below, B–ITA – 757629 to C-ITA-709990, and C–ITA-709991 & above. Same for the reduction gears. You get 17 different axle variants listed for the front and rear together. That’s the kind of precision you don’t get from a third-party reprint. The catalog number is 648233, release R/10-03 – it’s a genuine 2003 factory document.

Engine Overhaul Coverage — From Monobloc to Turbocompressor

The MOTORE RJ81403 section breaks down the engine into 30 sub-sections, covering everything from the monobloc and testata (cylinder head) to the turbocompressor and intercooler. Each sub-section has a clear illustration with callouts and part numbers. Need the air filter assembly? That’s on page 61. The inching pedal? Look under Trasmissione. The catalog uses Italian part descriptions, but the part numbers and diagrams are universal. For a general overview of the RJ81403 engine, you can refer to this Wikipedia article on diesel engines.

Does This Manual Cover the Hydraulic System?

Yes – the main hydraulic section (IMP.IDRAULICO PRINC.) includes the pump assembly, distributor, reservoir, and all the lines. You’ll also find dedicated hydraulic diagrams for the winch (Argano 3T and 5T), the rotation system, the stabilizers, and the boom extension. Every seal, hose, and fitting is listed with the original Manitou part number. If you need the brake circuit, that’s under its own heading with the master cylinder and pressure lines. The factory book also includes the electrical system – from the logic box to the rotating collector – so you can trace a wiring fault without guessing.

Use the Alphabetical Index to Find Any Part

Starting on page 3, the alphabetical index lists everything from AIR FILTER ASSEMBLY to WINCH 5T. Each entry has an illustration code and page number. The pictorial contents at the front let you flip directly to the section you need if you know what the part looks like but not the name. I’ve used this on a job where the technician needed a specific o-ring for the boom compensator cylinder – he found the boom section, identified the part in the drawing, and ordered it in five minutes. That’s the advantage of a factory-made index.

Why You Shouldn’t Trust Aftermarket Parts Catalogs for a Manitou

Every aftermarket reprint I’ve seen skips the serial number breaks. They’ll show one generic axle housing and call it good, then you order it and it doesn’t fit. This factory catalog includes a note that part numbers are continually updated – that’s why serial number ranges matter. The original file is from Manitou North America, not a copy house. It gives you the exact page numbers and illustration codes that align with the rest of the factory service documentation. If your shop also handles the MRT1432, check out Manitou MRT1432 M SERIES E2 Parts Catalog – Section: Frame Assemb. For the service procedures, you’ll need Manitou MRT1850 MRT2150 MRT2540 Operators Service Manual and Manitou MRT1850 MRT2150 MRT2540 2011 Operators Manual. Those combined with this parts catalog give you the full OEM data set.

Frequently Asked Questions

Can I use this manual for a different model like the MRT1432?

No, this is specific to the MRT2150 M Series E2.

What if I need a part that isn’t listed?

Because Manitou updates their parts continuously, the 2003 edition may not include the latest revision for every component. Contact your Manitou dealer with the machine’s serial number and the part description from the catalog. The related manuals listed above (for the MRT1432, service manuals) may also have additional illustrations. this Wikipedia article on diesel engines can give background on the engine family if you need general theory, but for parts ordering, stick with the factory catalog.
