Sperry New Holland OM 352A Parts Catalog – 45 Pages of Factory Parts Data

If you have ever tried to order a gasket or a bearing for an older agricultural engine without a proper part number, you know the headache. You end up with the wrong size, the wrong thread pitch, or a part that looks close but doesn’t seal. That waste of time costs you money. This Sperry New Holland OM 352A Parts Catalog fixes that. It is the factory-issued parts list for the Mercedes-Benz OM 352A/900.417 turbo engine used in Sperry New Holland equipment. 45 pages of exploded views, OEM part numbers, and cross-reference data from the original 1970s release.

Cylinder Head and Crankshaft: What’s Inside Group 2 and Group 3

Group 2 covers the cylinder head and cover – valves, springs, retainers, the head gasket. Group 3 goes to the crankshaft, main bearings, and connecting rods. The exploded diagrams show exactly how each piece fits, with Mercedes old and new part numbers listed side by side. If you are rebuilding the top end of an OM 352A, you need these pages to order the correct valve stem seals and head bolts. Page 2 includes the errata table that updates part numbers. Do not skip that page – I have seen guys order a Seal ring (part 007603 018104) using the old number and get a different diameter.

Fuel System Coverage: Injection Pump and Filters

Group 5 is the fuel injection pump. Group 6 covers the pump drive and fuel lift-pump. Group 7 is the fuel filter. If your OM 352A is hard starting or losing power, the issue is often in the injection pump or the lift pump diaphragm. This catalog gives you the exploded view of the pump drive assembly and the correct part numbers for the fuel filter element. No guessing – you see the exact Mercedes part number. The manual also includes the startermotor (Group 8), oil pump (Group 9), oil filter (Group 10), waterpump and cooling (Group 11), and turbocharger (Group 12). That covers every rotating and fluid-handling component on the engine.

Audience Fit: Who Needs This Parts Catalog

This is for the guy who owns a Sperry New Holland baler, combine, or forage harvester with the OM 352A engine. Also for the shop that services these machines. If you are a DIY mechanic working on old agricultural equipment, you know that aftermarket parts catalogs often skip the turbo version or merge diagrams. This manual is specific to the OM 352A/900.417 turbo. The parts lists are in four languages – English, French, German, Italian, Dutch – so you can read the description in your preferred language. The index on page 98 lets you find any part number fast. Keep it near the parts washer, not on a shelf.

Source Validity: Factory OEM Beats Aftermarket

This is not a third-party compilation. Sperry New Holland, a division of Sperry N.V., printed this in 1976. The cover reads “SERVICE PARTS CATALOGUE” and the inside shows the Mercedes-Benz engine type OM 352A/900.417 TURBO. The part numbers are direct from Mercedes – you can cross-check them at a Mercedes dealer. Aftermarket manuals often re-draw the diagrams and lose detail. This is a scan of the original factory issue. The part number table on page 2 lists old and new Mercedes numbers, so you can order the updated part. That level of accuracy keeps you from ordering a crankshaft main bearing that is 0.001 inch off.

3 Groups You Should Memorize

Group 1: Block – the engine block, oil pan, and mounting brackets. Group 4: Timing – the timing gears, chain, and tensioner. Group 5: Fuel injection pump – the heart of the fuel system. If you are tearing down an OM 352A, start with these three groups. The block group shows the cylinder liner arrangement and the main bearing caps. The timing group shows the gear timing marks – essential for getting the injection pump timing right. The fuel injection pump group shows the delivery valves and plunger assembly. Every part has a Mercedes number. That is what you need when your local parts house says “I need a part number.”

Frequently Asked Questions

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views, not torque values or repair procedures.

How are the groups organized?

Each group (1–12) covers a major engine system: block, cylinder head, crankshaft, timing, fuel injection, pump drive, fuel filter, starter, oil pump, oil filter, waterpump, and turbocharger. The diagrams show each component with callouts linked to a part number table. Use the index on page 98 to locate any part by name or group. The manual also includes an errata page (page 2) with updated part numbers for several items, including seal rings and gaskets. If you need to order a replacement cylinder head gasket, look at Group 2 and cross-check the part number against the errata to get the latest revision.
