Manitou M2 30, M2 40, M2 50, M4 30, M4 40 1998 Parts Catalog

You pull a filter off a Manitou M2 30 and the number’s rubbed off. Call the dealer? Wait two days. Grab a generic cross-reference? Risk the wrong micron rating. That’s why you need the factory Manitou M2 30, M2 40, M2 50, M4 30, M4 40 1998 Parts Catalog on your bench. 245 pages of OEM part numbers, illustrations, and filter cross-references that match exactly what Manitou bolted on at the factory. No guesswork, no “close enough.”

Parts Index and Filter Chart: Where to Start

This catalog opens with a clear Parts Index and a Filter Chart that covers every fluid system on the truck. Engine oil filters for Perkins 4.236, Perkins 1004, and Caterpillar are listed separately on page 1 — because mixing them up gets you a leak or a bypass valve that won’t seat. Air filter cartridges, transmission oil filters, fuel filters (both Perkins cartridge type and Cat canister type), hydraulic oil filter cartridges, and even the axle oil cooler filter for poultry cabs are all tabbed by page number. If you’re working on a poultry spec machine with the 84” or 77” cab, the filter list includes those too. Page 2 breaks down the model designation system so you know exactly which truck you’re dealing with: M2 is front-wheel drive, M4 is four-wheel drive, 30 means 6000 lb lift capacity, 40 means 8000 lb, 50 means 10,000 lb. P is Perkins, C is Caterpillar. The serial number range that this catalog covers is printed on page 1: M2300545, M240331, M2500263, M4300287, M4400371, M4500251 and below, plus the gasoline versions. If your serial falls in that range, this is your parts bible.

Engine, Transmission, Fuel: Three Critical Systems

You’re rebuilding a Perkins 4.236? Need the fuel injection pump seal kit? The catalog breaks down the engine group into individual components with illustration numbers and part quantities. Same for the Hurth axle and the Dana Spicer transmission — the identification plate locations are diagrammed on page 3 so you don’t confuse a torque-converter transmission with a hydrostatic unit. The fuel system section includes the pre-cleaner and turbo pre-cleaner II (poultry trucks). And if you’re chasing a hydraulic suction screen or a vaculator element (Nelson or Donaldson), it’s in here. I’ve seen guys order a fuel filter for a Perkins engine when they had a Cat — this catalog keeps that from happening because the part number is tied to the truck model and serial range. For deeper context on how diesel engines in these machines work, read this Wikipedia article on diesel engines.

Does This Catalog Cover Your Specific Model?

Look at the truck’s serial plate — located inside the cab behind the driver and to the right, or above the right rear tire on the frame. The catalog covers M2/4 30 thru 50 CP-P-G, M2/4 30 CP-PL-G, and M2 30 CP-PXL-G with manual forward/reverse transmissions. Serial numbers M2300545, M240331, M2500263, M4300287, M4400371, M4500251, plus the gasoline versions M230G0150 and M240G0150 and below. If your truck has a different prefix or a higher serial, call Manitou North America — the number’s on page 1. But for the vast majority of late-90s M-Series trucks, this is the correct parts catalog.

245 Pages of Factory Part Numbers

Every page is a scan of the original Manitou publication — catalog B238, revision R04-98B. No aftermarket recompilation, no third-party data entry errors. The part numbers are drawn directly from the factory master. The illustrations show the exploded view of each assembly, and the item numbers line up with a column that gives the part description, dimensions when needed, quantity per truck, and model applicability. Page 4 explains the ordering protocol: common hardware like nuts and bolts should be replaced with Grade 5 zinc or stainless steel; for everything else, use the part number listed. Don’t lose these pages — if you’re ordering a transmission or engine component, you need the exact item number. Need a parts breakdown for a different model? Check Manitou M2 30 40 50 Lift Truck 2000 Operators Manual or Manitou M2/M4 30/40/50 Series Operators Manual for operating procedures and maintenance intervals.

OEM vs Aftermarket Catalogs: Why It Matters

Aftermarket parts catalogs often group parts by “fits many models” and skip critical differences like the fuel filter thread pitch or the hydraulic suction screen micron size. This is an original Manitou publication, printed in 1998 and distributed by Manitou North America in Waco, Texas. The part numbers are the same numbers the dealer uses. If you’re doing a transmission overhaul, the Dana Spicer identification plate on the left-hand side of the transmission lower half is key — the catalog references it. And if you want to understand the full lubrication system, this Wikipedia article on diesel engines explains the oil circuit basics. Between the catalog and that background, you’ll order the right pump and filter.

Will this parts catalog tell me how to rebuild the engine?

No. This is a parts catalog, not a service manual. It gives part numbers, quantities, and illustrations for ordering. For assembly torque specs and procedures, you need the repair manual.

How do I find the correct part number for my transmission?

Start by locating the transmission identification plate on the left-hand side lower half. The catalog’s model designation page (page 2) will tell you if you have a torque-converter (C) or hydrostatic (H) unit. Then flip to the transmission section in the Parts Index. Match your truck’s serial range to the illustration — the item number leads to the part number. If you’re between serial ranges, call Manitou North America Parts at 800-425-3727. They’ll ask for your serial number and this catalog’s revision (R04-98B) to cross-reference. Write the serial number down before you call — it’s on the frame above the right rear tire. The catalog also includes the Hurth axle and Dana Spicer transmission sections, so you can order seals, gears, and clutches exactly.

If you work on these Manitou M-Series trucks regularly, this catalog belongs on your shop desk. The filter chart alone pays for itself the first time you order the correct fuel filter instead of wasting an afternoon with a universal. Pair it with Manitou M2/M4 Forklift Parts Catalog for complete coverage. Access the Factory Manual and stop relying on stamped-on numbers that wear off.
