New Holland OM 352 Parts Catalog – Factory Parts Breakdown

If you have ever ordered a part for a New Holland machine with an OM 352 and ended up with the wrong gasket, the wrong seal, or a bearing that didn’t fit, you know exactly why this Parts Catalog exists. That kind of mistake costs time and money. The aftermarket cross-reference books are hit or miss. I have seen guys install a piston ring that wasn’t even close to the right gap because they trusted a third-party number. A factory parts catalog kills that guessing. This is the Sperry+New Holland issue 496828, printed for the Mercedes-Benz OM 352/900.411 turbo engine. 45 pages, no fluff, no translations, just exploded diagrams and genuine part numbers.

Crankcase and Cylinder Breakdown

The first section hits the crankcase (page 3-B 3). Every bolt, every plug, every dowel pin has its own factory number. The cylinder head and cover are right after (page 7-B 7). If you are pulling the head on an OM 352, you need the correct head gasket. There are different thickness options depending on deck height. This catalog lists them by part number. Don’t trust an internet forum. Trust the factory drawing.

Crankshaft and Timing Specs

Section 3 covers the crankshaft (page 9-B11). The OM 352 uses a forged crank with specific main bearing sizes. The journal diameters are not published here, but the bearing shell part numbers are. You order those by the code in this book, not by a generic “fits 352” listing. Timing components are separate on page 13-B15. The gear train and injection pump drive gear are all indexed. If you replace a timing gear, match the tooth count and the keyway orientation from the diagram.

Fuel System: Injection Pump and Filter

Sections 5 through 7 cover the injection pump (page 15-B19), pump drive and lift pump (page 19-B23), and fuel filter (page 21-C 7). A parts catalog is essential when you are rebuilding a Bosch-style inline pump. The delivery valves, plungers, and governor parts each have their own number. The lift pump diaphragm part is there. The fuel filter head assembly—all listed. Do not mix up the pump drive coupling. The catalog shows the correct orientation and part numbers for the drive flange and rubber element.

Cooling System: Water Pump and Fan

Water pump and cooling section (page 29-C19). The OM 352 is a wet-sleeve engine and relies on good coolant flow. The water pump impeller, seal, and housing numbers are all broken out. Fan blade part numbers on page 33-C23. If you need a fan clutch or just the bolt pattern, it is there. Automotive Industry Overview background can explain why OEM cooling system parts are critical, but I will tell you this: using a wrong water pump can cavitate and overheat the engine in under an hour. Get the factory number.

Turbocharger and Lubrication

Turbocharger section (page 35-D 3). The OM 352 turbo variants (900.411) used a Garrett or KKK unit. The catalog lists the cartridge, turbine housing, and oil feed line part numbers. Oil pump (page 25-C11) and oil filter (page 27-C15) are separate. The oil pump gear clearance specs are not in a parts catalog, but the gear set part number is. You can verify the gear width by ordering the correct set.

Why the Factory Parts Catalog Matters for Your Build

If you are a farm mechanic, a diesel shop owner, or a hobbyist restoring an old New Holland combine or tractor, you need original documentation. Aftermarket parts catalogs renumber parts to their own system. You end up with a box of wrong pieces. The New Holland OM 352 Parts Catalog gives you the Mercedes-Benz factory numbers that any dealership or online parts house can verify. 45 pages, indexed by section (English, French, German, Dutch). The index on page 36-L 1 lets you cross-reference quickly.

Source Authenticity: OEM Factory Print

This is not a scanned reprint from some third-party aggregator. It is a direct digital copy of the original Sperry+New Holland publication from 1976 (issue 496828, superseding 496744). The page numbering uses the factory grid (e.g., 3-B 3). The drawings are crisp. The part numbers are exactly as they were when the engine was new. You will not find a section that says “refer to dealer” – every part has a number. The Automotive Industry Overview can tell you about standard parts numbering, but this manual predates modern electronic cataloging. It is the real deal.

Audience Fit: Who Needs This Catalog

Owners of New Holland equipment with a Mercedes-Benz OM 352 engine. That includes combines, forage harvesters, and industrial power units. Also DIY mechanics rebuilding the engine in a truck or generator set that uses this powerplant. If you are buying a used OM 352 and want to verify that all internal parts are available, this catalog shows you every last bushing and seal. Beginners need to understand that a parts catalog does not teach you how to assemble the engine. It gives you the numbers to order the right pieces. If you have never rebuilt a diesel, pair this with the service manual for torque specs and clearances.

Does this manual include torque specifications?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views only.

Can I use this to rebuild my OM 352 engine?

You need this catalog to order the correct bearings, gaskets, seals, and injector parts. However, you also need the factory service manual (separate document) for assembly procedures, torque values, and wear limits. The two manuals complement each other. Using this catalog alone will leave you without clearance specs or tightening sequences.

What years and engine variants does this cover?

This publication (issue 496828) supersedes issue 496744 and covers the Mercedes-Benz OM 352/900.411 turbocharged engine. It is the factory catalog for that specific turbo variant as used by Sperry+New Holland. Naturally aspirated OM 352 engines may share many parts but always cross-check the part numbers.

Is this an original factory document or a reprint?

This is a direct digital copy of the original Sperry+New Holland printed catalog from 1976. It is not a third-party reprint with altered numbering. The PDF preserves the factory layout, including the multi-language parts lists in English, French, German, and Dutch.

Drag this file onto your tablet, phone, or laptop and keep it in the shop.
