Manitou MLA628 Parts Catalog – 636 Pages OEM Exploded Views

Description

If you’ve ever tied up a machine waiting on the wrong part number from a third‑party sketch, you know the pain. The Manitou MLA628 Parts Catalog is the document that kills that headache flat. I’m Mike Callahan, and after 28 years of turning wrenches in San Antonio, I can tell you that guessing on parts eats time and money faster than a blown seal. This is the exact catalog that Manitou’s own parts desk uses – 636 pages of factory illustrations, reference numbers, and cross‑references. No aftermarket re‑drawn garbage. You open this, you see the part as Manitou drew it, with its code beside it.

Axle Differentials and Reduction Gears – Front and Rear

Front axle differential AX2553 and rear differential AX2554 are covered with separate exploded views. Need to pull the reduction gear on a rear axle? Page 611 shows AX1596 with every bearing, shim, and seal called out by the factory part number. The same treatment applies to brake discs (AX1593, AX1597) and axle housings. You don’t need to call the dealer and pray the guy on the phone has the right diagram – you have it in your hand. Manitou MLA628 Parts Catalog is the only source that lines up with what actually ships from the factory.

Boom Assembly and Carriage – Section 5BA305

Boom assembly starts on page 81. Carriage and forks on page 77. If you’re rebuilding a boom that has wear in the pivot pins, the exploded view shows exactly which bushing, pin, and retaining ring belong where. The same goes for the carriage – you can order the weldment or the individual fork stops. This catalog is organized by assembly code, so you can jump from a worn part straight to the illustration without digging through a generic index.

Engine Block and Head Assembly – AP1538 / AP1540

You don’t rebuild an engine in a Manitou MLA628 without knowing which head gasket kit fits. Engine block AP1538 (page 415), head assembly AP1540 (page 423), rocker arm assembly AP1541 (page 427) – each section has a parts diagram with the factory part number stamped next to the component. If you need the timing cover and cam gears, that’s AP1542 on page 431. The gasket kit AP1553 is on page 469. Having this catalog means you can order the right pistons, rings, and bearings for the job the first time. I’ve seen guys spend two weeks waiting for a wrong main bearing set – that doesn’t happen when you source from OEM diagrams.

Electrical Schematics and Misc. Details – 11AA684, 11AA686

Electrical gremlins on a telehandler are a special kind of torture. This catalog includes three sections of electrical misc. details (11CB491, 11CC112, 11CD80) plus a dedicated primary schematic (11AA684, page 289) and a lights schematic (11AA686, page 301). The wiring is factory‑drawn with color codes. For a machine that has a powershift transmission and a boom hydraulic system with multiple solenoids, you need the OEM wire colors to trace a short. K-D Manitou MVT 1230L MVT1230LC Parts Catalog – 264 Pages covers a different model, but for the MLA628, this is the one.

Hydraulic Cylinders and Control Valves – 10CA212, 10DA196

The lifting cylinder assembly 10CA212 (page 253), the compensating cylinder 10CB34 (page 257), the tilting cylinder 10CD80 (page 265), and the steering cylinder 10CE24 (page 269) are all illustrated with individual seal kits and rod parts. Control valve assemblies – 10DA196 (page 273) and 10DA246 (page 277) – show the spools, springs, and O‑rings. If you are rebuilding a leaky boom extender, you go to page 261 for the boom extending cylinder 10CC110. This catalog doesn’t tell you how to rebuild it – that’s a service manual job – but it gives you every part number you need to order so the job doesn’t stop.

Source Validity – Why OEM Matters

This is a reprint of the original Manitou catalog number 547885P, R01‑04. The title page shows Manitou North America’s own address in Waco, Texas, and their parts phone line (800‑425‑3727). When you order from that desk, they use this same document. A third‑party parts book will sometimes merge two revisions or mis‑label a seal. This one has the factory illustration codes like 4AA368 for the air filter assembly and 6BA138 for the brake circuit. Those codes let you cross‑reference with Manitou’s computer system. You can verify any part by calling the dealers with the code from the page.

3 Sections of Cab Misc. – Why You Need Them

Cab misc. is broken into ten sub‑sections, from 8AA297 (page 125) through 8AB551 (page 171). That tells you that the factory intends for you to find every interior piece – trim panels, seals, glass, wiper motors, roof panels – with a dedicated illustration. I have wasted an afternoon trying to figure out which weatherstrip fits a door on an older MLA628. With this catalog, you turn to page 137 for cab misc. 3/10 and see the exact extrusion. Same for electrical misc. details – three separate sections because the MLA628 has a complex wiring harness with relays and fuses on page 315 (11CA59).

How do I confirm a part number without an exploded view?

Every section includes the illustration code and the factory part number next to the callout. Cross‑reference with the alphabetical content index at the front (pages 3‑4) to find any assembly by name.

Does this catalog include torque specs or service procedures?

No. This is a parts catalog, not a service manual. It gives you part numbers, quantities, and illustrations. For procedures, you need the corresponding service manual. But if you are ordering parts for a rebuild, this document is the only way to get the correct number without calling the dealer and holding your breath.

Don’t tie up a machine waiting for a wrong bearing or a mis‑labeled hose. K-D Manitou K5705, K5797, K5755, K1479, K1787 1991 Parts Catalog covers older models, but for the MLA628 with powershift and series 3‑E2, this is the document. this Wikipedia article on diesel engines covers the theory behind the Perkins drivetrain commonly used in these machines, but the part numbers only live in the factory catalog. this Wikipedia article on diesel engines provides general background, but it won’t help you find the right oil cooler for AP1545.
