Manitou MLT 630, MLT 634, MLT 731, MLT 735, MLT 741 2007 Parts Catalog

You order a part from a generic list and it doesn’t fit. Now the machine is down, and you’re out the shipping cost. That’s the kind of waste that gets under my skin. This 2007 Manitou Parts Catalog for the MLT 630, MLT 634, MLT 731, MLT 735, and MLT 741 is the factory document that tells you exactly which part number to order, down to the thread pitch and O-ring size. 1211 pages of OEM data, no cross-reference guesswork.

1211 Pages of Factory Part Numbers

This is not a condensed aftermarket list. Every page is an exploded view diagram with callouts to the original part number. The catalog covers the engine, transmission, hydraulics, steering, brakes, electrical, and chassis. Each section groups parts by assembly, so you see the relationship between components. For example, the air filter cartridge on page 2 of the OCR shows the part number 4 AA 321 for the filter element and the security cartridge. You get the exact numbers for the MLT 630 Turbo Série C – E2 and all other variants. No fishing through online forums.

Models Covered: Beyond the Big Five

The title lists the MLT 630, 634, 731, 735, and 741, but the catalog also includes the MLT 742 Turbo Série 3 – E2 and the MLT 1035 L Turbo LSU Série 3 – E2. If you have a machine from that series, this catalog will have the parts. The header page lists all the variants: MLT 630 Turbo Série C – E2, MLT 634 Turbo LSU Série C – E2, MLT 634 120 LSU Série C – E2, MLT 634 120 LSU PS Série C – E2, MLT 731 Turbo Série C – E2, MLT 731 Turbo LSU Série C – E2, MLT 735 120 LSU Série 3 – E2, MLT 735 120 LSU PS Série 3 – E2, MLT 741 120 LSU Série 3 – E2, MLT 741 120 LSU PS Série 3 – E2, and the two extras. That’s 12 distinct model variants covered.

Hydraulic and Engine Filter Identification

Filters are one of the most commonly misordered parts. The catalog shows you the exact cartridge for the air filter, oil filter (engine and transmission), hydraulic return oil filter, fuel filter, and heating filter. On page 2, you can see the part numbers for the air filter cartridge and the security air filter cartridge. The oil filter for the transmission is listed separately from the engine oil filter. If you need a fan belt or alternator belt, those are in there too. The belt part numbers are grouped by application – MLT 630/731 Turbo, MLT 634/731 Turbo LSU, etc. This saves you from buying a belt that is two inches too long. The catalog also includes the filling plug filter and the heating filter, ensuring you get the right element for every fluid system on the machine.

What This Catalog Is Not

This is a parts catalog, not a repair manual. It does not contain torque specs, step-by-step overhaul procedures, or wiring diagrams. But if you’re rebuilding a hydraulic pump or replacing a cylinder, you need the correct seal kit and piston. This catalog gives you the part number for the seal kit. Then you can use the service manual for the torque values and assembly order. The catalog and the service manual work together. I recommend having both on the bench. For related manuals, see the Manitou MLT Series Parts Catalog for earlier years, or the Manitou MLT Series Parts Catalog 2010 for later updates. The Manitou MLT 735, MLT 741, MLT 742 Parts Catalog – 1255 Pages OEM is another heavy hitter if you only need those models.

3 Reasons to Use OEM Parts Documentation

First, the part numbers are verified by the manufacturer. Aftermarket catalogs often combine multiple supersessions or omit specific revision levels. This catalog is the original OEM print from 2007. Second, the exploded views show how parts fit together. You can see the fasteners, washers, and clips that are easy to miss. Third, the catalog includes quantity and reference numbers for each assembly, so you order the correct number of bolts, not just one. For a deeper understanding of the diesel engines used in these machines, you can read this Wikipedia article on diesel engines. But for part numbers, trust the factory document.

If you’re curious about engine theory, this Wikipedia article on diesel engines covers the basics. However, when you’re in the shop with a torn gasket, theory won’t help. You need the part number.

Frequently Asked Questions

Is this a repair manual or a parts catalog?

Parts catalog. You get part numbers, not step-by-step repair.

Does it cover the MLT 742?

Yes, the MLT 742 Turbo Série 3 – E2 is listed on page 1 of the catalog. Both the 742 and the MLT 1035 L Turbo LSU appear in the model list, so you can order parts for those machines too. The catalog includes all models from the MLT 630 through the MLT 1035, but the primary focus is on the five models in the title. If you need parts for a 742, this catalog will work.

What year is this catalog valid for?

Published 06/2007. Replacements or revisions may exist.

Can I use this catalog to find torque specs?

No. This is a parts catalog, not a repair manual. Torque specs are in the service manual. But if you need the correct bolt or nut to torque, this catalog gives you the OEM part number so you order the right fastener.
