Manitou MB-40, MB 40 B, MC-50 B, MC-50 C, 4RM-35 B Parts Catalog

If you’ve ever ordered a part for a Manitou forklift using a reference number from a generic drawing and got the wrong piece, you know the pain. That’s exactly why this factory Manitou MB-40, MB 40 B, MC-50 B, MC-50 C, 4RM-35 B Parts Catalog exists. It’s 180 pages of OEM part numbers and real exploded views, not aftermarket redraws. Page 1 lays out the three machine configurations so you can immediately identify which drivetrain you’re dealing with.

3 Machine Configurations Detailed

The catalog breaks down the models into three groups. The 4×4-4D group covers the MB-40 and MB 40 B with a D-179 engine and IH final drives. The 6×4-HD group covers the MC-50 B and MC-50 C with a D-239 engine and ZF reduction. The 6×4-IRM group covers the 4RM-35 B also with a D-239 but with IH final drives. Each group has its own parts listings and exploded views. Page 1 shows the full breakdown.

One glance at that page and you know exactly which engine and transmission your machine has. No guessing. You can also see how the MC-50 K and 4RM-40 K variants fit in, but this catalog sticks to the base models. If you need the later versions, check the related K-D Manitou MVT 1230L MVT1230LC Parts Catalog – 264 Pages for additional coverage.

Manitou MB-40, MB 40 B, MC-50 B, MC-50 C, 4RM-35 B Parts Catalog: Organization

The catalog is split into groups corresponding to each mechanical assembly. Each group contains exploded views with reference numbers, followed by a full parts list. The list includes the part number, description, quantity per assembly, and any serial number restrictions. Standard hardware like bolts, nuts, and lock washers are not drawn in the views. They are listed in a separate hardware table under each component, identified by size and grade. That keeps the drawings clean and shows you exactly which fastener goes where. For example, a bolt might be listed as “40 40 419 S 3/8″ x 22 mm”. The “S” means bolt. The table tells you the quantity needed even if it’s not drawn.

Page 1 also explains the abbreviations and coding used throughout. If you see a reference number with a suffix like “(xxx)”, that means the part applies only to machines from that serial number onward. Ignore that and you might order the wrong component.

Do You Need the Reference Number or the Part Number?

This is the biggest mistake I see with aftermarket catalogs. The reference number on the exploded view is not the part number. Use only the actual part number listed in the table. The catalog explicitly warns: “Les numéros de repère ne doivent pas être utilisés pour la passation des commandes.” Translation: reference numbers are for location, not ordering. Always quote the part number from the list. If you skip that step, you’ll get the wrong piece and waste a day. This catalog gives you the real part numbers, not a rehash. Compare that to a third-party PDF that might list a different number because they traced a drawing wrong.

If your machine has a later serial number, check the K-D Manitou K5705, K5797, K5755, K1479, K1787 1991 Parts Catalog for updated parts. The 1991 edition may cover supersessions.

Standard Hardware: Listed Separately for a Reason

The explosion of a transmission might show ten gears but no bolts. That’s intentional. The hardware is extracted to a separate table below each component group. The table lists each fastener by size, type, and quantity. If the quantity isn’t shown, it defaults to one. This method keeps the drawing readable and forces you to check the hardware table. You don’t want to order a seal without knowing you also need the six bolts that hold the cover. The catalog includes all standard hardware type codes: S for bolt, M for nut, F for lock washer. Use those codes when ordering from your dealer.

And if you are working on the D-179 or D-239 engine, this Wikipedia article on diesel engines can give you background on the series, but for parts you need the factory listing. Don’t rely on general knowledge – use the catalog for exact numbers.

Get the Right Part Number Every Time

When you open this catalog, start with Page 1 to identify your model group. Then find the appropriate section. Cross-reference the exploded view with the hardware table. Write down the part number – never the reference number. If you need a part that has a serial number restriction, verify your machine’s serial against the listing. The catalog covers the MB-40, MB 40 B, MC-50 B, MC-50 C, and 4RM-35 B. If you have a variant like the MC-60 K, the 2000 edition K-D Manitou K5705, K5797, K5755, K1479 2000 Parts Catalog | OEM Factory Specs may give you the additional coverage.

One more thing: this is strictly a parts catalog. It does not contain torque specs or repair procedures. For that, you need the service manual. But if you are ordering parts, this is the only document you should trust. Aftermarket catalogs often redraw the views incorrectly or drop hardware items. This one comes direct from Manitou’s print files.

Don’t guess part numbers. Access the Factory Manual and get the right fastener the first time.

Frequently Asked Questions

Can I use this to order parts from any dealer?

Yes. Use the part numbers listed (not reference numbers) and any Manitou dealer can process the order.

Does this catalog include torque specs or repair procedures?

This is a parts catalog, not a service manual. It contains part numbers, quantities, and exploded views for ordering correct components. For torque specifications, clearance measurements, and overhaul procedures, you must reference the factory service manual for your specific Manitou model. The exploded views here do show the exact position of bolts, washers, and seals, which can assist during reassembly, but they do not list torque values. You can find related service manuals in our collection of OEM documentation.

What models are covered exactly?

MB-40, MB 40 B, MC-50 B, MC-50 C, and 4RM-35 B.

How are standard hardware items like bolts and washers listed?

They are not shown in the exploded views. Instead, they appear in a separate hardware table under each component group, identified by size and grade with type codes (S, M, F).
