Manitou MLT 735 120, MLT 741 120, MLT 742 2005 Parts Catalog – 998 Pages

I’ve lost count of how many times I’ve seen a shop tie up a Manitou MLT 735 120, MLT 741 120, MLT 742 2005 Parts Catalog for two days because the parts guy ordered the wrong hydraulic filter. That’s what happens when you rely on a cross-reference chart instead of the actual factory parts catalog. This 2005 Parts Catalog for the Manitou MLT 735 120, MLT 741 120, and MLT 742 puts the exact part numbers in front of you, organized by machine series and build date. It’s 998 pages of OEM plate drawings, numerical indexes, and nomenclature tables. If you’re pulling a transmission or rebuilding a boom, you need this on the bench next to you – not a third-party PDF that might have renumbered parts.

Index Plancher System: How to Navigate 998 Pages

The catalog uses a three-level numbering system. On page 2 you’ll see the INDEX PLANCHE – a grid of plate numbers like 3.64.01 through 3.64.91. Each plate corresponds to a specific assembly: engine, hydraulic pump, cab, boom, etc. You don’t flip page by page; you find the plate number from the index, then jump to the corresponding section. The bookmarks in the PDF mirror this structure. The INDEX NUMERIQUE is a numerical list of every part number in the catalog, cross-referenced to the plate where it appears. That means if you have a part number from the old part, you can find its exact location in minutes.

Serial Number Range: Why It Matters for the MLT 742 Turbo

This catalog covers MLT 735 120 LSU Series 2-E2, MLT 735 120 LSU POWERSHIFT Series 2-E2, MLT 741 120 LSU Series 2-E2, MLT 741 120 LSU POWERSHIFT Series 2-E2, and MLT 742 Turbo Series 2-E2. Page 1 lists the publication date as 2005 and includes a revision history from 2003. If your machine has a different series number, this catalog will not match. I’ve seen guys try to use a Series 1 catalog for a Series 2 machine and end up with a starter that had the wrong nose cone. Check the serial number plate on your machine before you order.

What’s Inside the INDEX PLANCHE Section?

Plates 3.64.30 through 3.64.44 cover powertrain components – that’s the engine block, cylinder head, oil pan, and related hardware. Plates 3.64.50 through 3.64.57 will get you the transmission housing and gears. For the hydraulic system, look at plates 3.64.60 through 3.64.75. The boom and mast are covered in plates 3.64.80 through 3.64.91. Each plate includes an exploded view drawing with callouts, a parts list with reference numbers, and quantities. If you’re rebuilding a MLT 742 turbocharger, you need plate 3.64.40 specifically – that’s the engine air intake and exhaust section.

Parts Catalog vs Service Manual: Two Different Tools

This is a parts catalog, not a service manual. It will not tell you how to remove the cylinder head or what torque to use on the injectors. What it will do is give you the right part number for the injector, the sealing washer, and the fuel line. For repair procedures, you want the Manitou MLT 735, MLT 741, MLT 742 Parts Catalog – 1255 Pages OEM (that’s a different document). But when you’re on the phone with the parts counter, having the factory catalog open prevents you from ordering the wrong component. I’ve been burned by aftermarket catalogs that left out the superseded parts – this one includes all revisions up to 2005.

3 Reasons to Stick with OEM Documentation

First, the part numbers are verified against the actual machine build. Second, the drawings show the exact configuration – including options like POWERSHIFT vs LSU. Third, the nomenclature includes multiple languages (French, German, Spanish, English) so if your machine was originally sold in Europe, you can match the local part numbers. Third-party catalogs often merge different series into one generic drawing – that’s how you end up with a brake caliper that doesn’t fit. If you want to understand how diesel injection timing affects component selection, read this Wikipedia article on diesel engines – but for part numbers, stick to the factory source.

• Manitou MLT 742, MT 1033 2003 Parts Catalog – 1046 OEM Pages

Also, this Wikipedia article on diesel engines provides good background on the theory, but when you need a part number, come back to the factory catalog.

FAQ

Does this catalog include diagrams for the powertrain?

Yes, plates 3.64.50–3.64.91 cover driveline and axle components.

I have a MLT 741 120 with a Perkins engine. Will I find the correct injector part numbers?

The catalog is organized by machine model and component group, not by engine brand. You will need to identify the engine series from your machine’s serial number, then cross-reference to the engine section (plates 3.64.30–3.64.44). The numerical index at the back of the catalog allows you to search by any known part number. If your injector has a previous part number, look up that number in the index and it will direct you to the correct plate. Aftermarket parts lists often omit the superseded numbers, but this factory catalog includes all revisions from the first edition through the 2005 update, so you can trace the part history.

If you’re putting one of these machines back together, don’t gamble on parts that might be wrong. Access the Factory Manual and get the exact reference you need.
