Manitou MT523, MLT523 Parts Catalog – OEM Factory Specs

If you’re chasing a part number for a Manitou telehandler and the dealer wants a serial number before they’ll even talk to you, this is the solution. I’ve spent 28 years turning wrenches, and half the battle is getting the right part the first time. Aftermarket catalogs leave out mounting variations or skip the brake circuit details you need when the machine is down. That’s why the Manitou MT523, MLT523 Parts Catalog from AutoRepairManuals stays open on my workbench. 810 pages of factory exploded views, part numbers, and illustration codes that match what Manitou North America prints.

Brake Lever Assembly and Pedal Circuit – Exploded Views

Brake issues on a telehandler can be dangerous. This catalog includes the BRAKE LEVER ASSEMBLY (6BA122) and the BRAKE PEDAL AND CIRCUIT ASSEMBLY for both 1st and 2nd mounting. Page 135 shows the lever assembly with every spring and pin. Need the pedal circuit? Page 137 covers the 1st mounting break pedal assembly—note the spelling in the index, it’s a transcription quirk but the part numbers are correct. You get separate sections for each mounting revision so you don’t order the wrong master cylinder.

7 Engine Sub-Sections Covered

Engine breakdown is where most catalogs fall short. Not this one. You get dedicated sections for CYLINDER HEAD, CYLINDER BLOCK, CONNECTING RODS/CRANKSHAFT, FLYWHEEL HOUSING, EXHAUST MANIFOLD, ALTERNATOR, and GASKET SETS—split by MT523 and MLT523. Each engine sub-section has its own illustration code and page range. For the MLT523, the cylinder head section (AP1205) lists valves, guides, and seals with OEM part numbers. The gasket sets (AP1219) save you from piecing together a kit.

Does This Catalog Cover Both MT523 and MLT523?

Yes. It covers the MT523 and the MLT523 Turbo, series A, serial numbers 162006 to 204733. The catalog separates each model where parts differ. For example, AIR INTAKE SYSTEM (MLT523) is on page 53, while the MT523 intake is on page 49. CAB DOOR assemblies are listed separately for each model. If you have mixed fleets, you need one book that handles both. This is it. Related manual: Manitou MT523 MLT523T Parts Catalog gives you the same depth for the T variant.

Air Intake Systems and Boom Assemblies

Two areas that get misordered are intake parts and boom hardware. The intake system sections show the air filter housing, ducting, and clamps with exact illustration codes. The BOOM ASSEMBLY (5BA151) covers the main structure, and BOOM HOSE COMPARTMENT (5BA152) shows hose routing and clamps. These are critical when replacing a worn hose bundle—you need the correct length and fitting orientation. The catalog uses pictorial contents at the front and alphabetical index so you can find any assembly in under a minute.

Source Authenticity: OEM Manitou Document

This is a genuine Manitou North America catalog, Catalog 547730P. I trust OEM documentation because aftermarket reprints often scramble page numbers or omit mounting variations. Compare: the 2nd mounting brake lever installation (6BB118) has different brackets than the 1st mounting (6BB71). A third-party catalog might collapse them into one generic diagram. That gets a tech ordering the wrong part on a Friday afternoon. With factory documentation, you see the exact difference. Also available: Manitou MLT523 Operators Manual – Factory Specs & Safety for operational details and Manitou MT523 MLT523 Operators Manual – Factory Safety & Specs for daily reference.

What section covers the brake system?

Brake lever assembly (6BA122) on page 135, brake pedal and circuit assemblies on pages 137 and 145. Two separate brake lever installations for 1st and 2nd mounting.

How do I know if this catalog matches my machine’s serial number?

This catalog is for series A, serial numbers 162006 to 204733. Check your serial plate on the frame. If yours is outside that range, verify with Manitou North America at the number printed inside the manual. Internal combustion engines are covered in detail—if you need background on diesel operation, see this Wikipedia article on diesel engines or this Wikipedia article on diesel engines. But for the parts themselves, you need the factory catalog.

Stop wasting time cross-referencing aftermarket part numbers. Access the Factory Manual and have the correct exploded diagram and OEM part number for every nut, bolt, and brake piston on your Manitou MT523 or MLT523.
