Manitou MLT630 T, MLT634 120 LSU, MLT731 T LSU, MT732 Parts Catalog

Figuring out which part number you need for a Manitou MLT630 T, MLT634 120 LSU, MLT731 T LSU, MT732 Parts Catalog shouldn’t take three phone calls and a prayer. I’ve been wrenching in San Antonio for 28 years, and nothing burns my time worse than ordering the wrong brake lever assembly because the aftermarket diagram had the wrong mounting variant. This is the OEM Parts Catalog — printed from Manitou North America’s own files — and it fixes that problem. 1300 pages of exploded views, part numbers, and cross-references that actually match the machine on your lift. If you’ve been relying on photocopied dealer pages or scanned PDFs that look like they were run over by a truck, this is the upgrade.

Brake Hydraulic Circuit Coverage

Brake systems on these telehandlers aren’t interchangeable across models. The BRAKE HYDRAULIC CIRCUIT for the MLT634 and MLT731 lives on page 243, with its own illustration code 6BA123. The MT732 uses a separate circuit — 6BA124 on page 251. If you pull a master cylinder from a 634 and try to bolt it onto a 732, you’ll be bleeding air for an hour. This catalog gives you the exact part numbers for each circuit, including seals and lines. No guessing which O-ring fits. You also get BRAKE LEVER ASSEMBLY (page 241) and separate installation setups for the MLT630, 731, MT732 (6BB90) versus the MLT634 (6BB99). That level of detail matters when you’re ordering from a dealer and they ask for your serial number.

Air Intake Systems – Model-Specific

The AIR INTAKE SYSTEM section breaks down into three separate listings depending on which model you’re working on. For the MLT63 and 731, it’s code 4AA315 on page 59. The MLT634 gets its own — 4AA316 on page 65. And the MT732 uses 4AA314 on page 53. Each page shows the filter housing, pre-cleaner, ducting, and clamps with part numbers that include supersession information. If you’re replacing an intake hose on a 634, you don’t want the 731 hose — different routing, different clamps. This catalog saves you the return trip.

1300 Pages of Factory Part Breakdowns

You read that right — 1300 pages. That covers everything from the CAMSHAFT, TIMING GEAR (AP1494, page 965) down to DECALS, CARDS (12AA290, page 869). Each section is laid out by illustration code and page number, so you don’t flip through a phone book looking for one bolt. The alphabetical contents index at the front lists every major assembly: cab components, cylinders, drive axles, alternator installations. Need the alternator installation for an MT732? That’s AP1486 on page 927. For the MLT634 it’s AP1517 on page 1061. Everything is cross-referenced by model and mounting variant — first mounting, second mounting, third mounting. If you’ve ever ordered a tilt cylinder for a 731 and got the wrong one because there are three different tilt cylinder assemblies for that model, you’ll appreciate the precision.

Who Needs This Catalog?

If you maintain a fleet of Manitou telehandlers — or just own one and fix it yourself — this catalog is the difference between ordering the right part on the first call and paying restocking fees. I’ve seen shop owners waste $200 on a wrong alternator bracket because they used a third-party site. This manual is the raw OEM data from Manitou North America, based in Waco, TX (catalog 547848P, revision R10-08). It covers the MLT630 T, MLT634 120 LSU, MLT731 T LSU, and MT732 across the B-E2 series. If you want to know how to read the exploded diagrams, this Wikipedia article on diesel engines won’t help directly, but it’s background on the engine platforms you’ll be working with. For the part numbers themselves, stick to this catalog.

Source Authenticity – OEM vs. Aftermarket Trash

Aftermarket parts catalogs often combine multiple model years into one drawing, leaving out the mounting variants that matter. This one came straight from the Manitou factory. The PDF is the same file the dealer prints from. Look at the this Wikipedia article on diesel engines for general engine theory, but for hardware numbers, trust the OEM document. I’ve been burned by aftermarket manuals that skip the AIR CONDITIONING appendix (page 1242) because “it’s optional.” This catalog includes the entire appendix. No shortcuts.

FAQ

Does this catalog include part numbers for the brake system?

Yes. The brake hydraulic circuit is covered for the MLT634/731 on page 243, for the MT732 on page 251, plus separate brake lever assembly and installation sections. You get every seal, line, and lever part number.

How are the diagrams organized — by model or by system?

By system first, then split by model and mounting variant. For example, CAB, DOOR ASSEMBLY, MISC. appears as 1st mounting and 2nd mounting for the MLT630/634/731 (pages 353 and 385), and as a separate section for the MT732 (page 321). You always know exactly which diagram matches your machine’s build date and serial number range. The alphabetical contents at the front lets you find the system, then the illustration code leads you to the right page. It takes about 10 seconds once you get used to it.

Stop cross-referencing blurry dealer faxes. Access the Factory Manual and get the exact part number the first time. Your machine’s downtime is expensive enough without ordering wrong parts.
