Manitou MLA628-120 Parts Catalog

If you’ve ever ordered a part for a Manitou and ended up with the wrong gasket or a bracket that doesn’t fit, you know why a factory parts catalog matters. The Manitou MLA628-120 Parts Catalog runs 878 pages of OEM-sourced breakdowns, direct from Manitou North America, Waco, TX. This isn’t a generic aftermarket compilation – it’s the same book the dealer parts counter uses. You get the exact part numbers, supersession notes, and illustration callouts tied to your machine’s serial number range.

Parts Breakdown for Powertrain and Hydraulics

Page 4 of the catalog shows how they group components like the air filter cartridge, alternator belt, and fan belt – each tied to specific machine variants (MLT 630, 731, 634, etc.). Every exploded view includes part numbers, not just descriptions. You can cross-reference the “AA 321” group callouts to find the exact cartridge for the air filter or the correct fan belt length. That means fewer returns and less downtime waiting for the wrong piece to come in.

What the 878 Pages Actually Cover

This catalog is organized by assembly groups: engine, transmission (Powershift), hydraulics, axle, brakes, steering, cab, and electrical. Each group has its own index, so you flip directly to the section you need instead of guessing page numbers. The manual includes multiple update indices (IC 403, IC 485, IC 494) to reflect parts changes from 2004 through 2007. If your machine falls after serial number 187632, you’re covered.

Does This Manual Cover the MLA628-120 LSU Powershift?

Yes, that exact model. The cover reads MLA628-120 LSU POWERSHIFT SERIES 3-E2. If you’re working on a standard MLA628 or an earlier Turbo variant, you’ll need a separate catalog. This one is specific to the 120 LSU with Powershift transmission. The parts callouts reflect the housing, gears, and clutch packs unique to that transmission. Don’t waste money on parts intended for the older directional shift models.

Updates and Bulletins – Why You Pay Attention to Revisions

Manitou issued catalog updates in 2004, 2006, and 2007. Each update adds or supersedes parts – wrong part numbers get corrected, and new components get added. The catalog shows the update date next to each assembly. If you’re using an old printed copy or a third-party PDF, you’re likely missing these revisions. This digital file keeps the factory bulletins intact. Page 1 even includes the note: “Manuals are continually updated … contact your dealer for latest information.” You get the latest published version.

Audience Fit – Who Needs This 878-Page Parts Catalog

Park your ego at the bay door if you think you can eyeball a part. I know techs who’ve ordered a $400 hydraulic pump only to realize the mounting flange changed after a certain machine number. This catalog eliminates that guesswork. Fleet managers, mobile repair guys, and serious DIY owners who run a MLA628-120 will use this to verify every gasket, seal, and fastener before calling the dealer. The exploded views save you from disassembling something twice to read a worn-out part number.

Source Validity – Why OEM Beats Aftermarket

Aftermarket parts catalogs often redraw the illustrations and drop the torque values, thread sizes, and update notes. This is a direct factory file – scanned from the original Microlog catalog ref CD547866. The PDF includes the Manitou North America address and parts department phone number (800-425-3727) because it’s their own publication. You can verify part numbers against your local dealer with confidence. Compare that to a generic website that lists “compatible” parts – not the same thing.

Need a deeper understanding of the diesel engine in this machine? See this Wikipedia article on diesel engines for fundamentals on injectors and fuel systems. But for part numbers, you need the factory catalog.

3 Reasons to Use the OEM Parts Catalog Instead of a Generic List

• Exploded views with callout numbers tied directly to the part number – no translation errors.
• Update history prints right on the page so you know when a part superseded.
• Factory groups match the actual machine – not an aftermarket rearrangement.

FAQ

Can I use this catalog for the MLA628 non-LSU version?

No. This catalog covers only the MLA628-120 LSU Powershift Series 3-E2.

How do I know if a part number has been superseded after the 2007 update?

Check the update column next to each group. The catalog lists the IC index (e.g., IC 494 for 02/2007) that revised that specific assembly. If your machine is newer than the last published update, call Manitou Parts at the number on page 1: 800-425-3727. They can confirm whether a later revision exists. The manual also includes blank observation fields where a dealer may have handwritten bulletin changes – that’s common in field-used copies. Always verify high-dollar parts with your dealer before ordering, especially if your machine serial falls after 187632.

When you’re standing at the parts counter with a torn oil seal in one hand and a phone in the other, having the factory part number saves you the “uh, it’s the one under the bracket” conversation. Access the Factory Manual now and keep the MLA628-120 running without the wrong parts pile.
