Ford LSG-423, SSD-327, SSD-437, SSD-655, SSD-681 Parts Catalog

If you’ve ever ordered a gasket set for a Ford industrial engine and ended up with a part that didn’t match the casting number, you know the pain. Wasted time, return shipping, and a machine that sits idle while you hunt for the right piece. That’s exactly why this 41-page factory Ford LSG-423, SSD-327, SSD-437, SSD-655, SSD-681 Parts Catalog belongs on your workbench. It’s the same binder Ford Power Products distributors used to look up part numbers before everything went digital – except this one isn’t scanned from a third-generation copy. It’s a clean, readable PDF of the original Ford publication.

This catalog covers the diesel line: SSD-327 (168 CID, 3-cylinder), SSD-437 (224 CID, 4-cylinder), SSD-655 (335 CID, 6-cylinder), and SSD-681 (495 CID, 6-cylinder). Also included is the LSG-423 gasoline engine (2.3L, 4-cylinder). Every section is organized by engine system, so you go straight to the assembly you need. The illustrations show reference numbers keyed to the parts list – no guessing which bolt goes where. Page 36, for example, shows the alternator assembly with every bracket and pulley identified by Ford part number. Want the fan blade? That’s on page 22. Timing gear cover? Page 6. It’s all there.

Cylinder Block and Head: Finding the Right Casting

The block-cylinder section (page 4) lists the bare block, cylinder liners, and core plugs. If you’re rebuilding an SSD-437 and need to know whether your engine uses a dry or wet sleeve, the illustration and part number tell you exactly which casting you need. Cylinder head assembly is on the same page – includes valves, guides, and springs. Page numbers match the index, so you don’t flip through forty pages looking for one gasket. The rocker arm cover and front timing gear cover sections are separate, because Ford knew you’d need to order them independently.

Fuel System Breakdown: Injectors, Filters, Lines

Fuel injector assembly (page 33) and fuel filter (page 34) are detailed with the correct injection nozzles and filter heads. The fuel system for 4-cylinder engines is on page 26, and for 6-cylinder on page 30. Each page shows the complete fuel line routing – steel lines, clamps, and return hoses. If you’re dealing with a leaking injector line on an SSD-655, you look up the reference number and order the exact pre-formed tube. No bending copper lines from a universal kit, because that never seals right.

Camshaft and Crankshaft: Identifying Wear Parts

The camshaft and bearings section (page 14) lists the camshaft gear and thrust plate. Crankshaft and bearings (page 10) gives you the main bearing set, rod bearings, and thrust washers. When you’re ordering a bearing kit for an LSG-423, the catalog shows the year-range symbol – for example, ’72/75′ means those parts were used from 1972 to 1975 and then changed. That little detail saves you from buying a bearing set that was superseded three times. Connecting rods and bearings (page 8) and pistons and rings (page 8) are also in there, with ring gap specs and piston pin dimensions. Note: the manual lists parts, not service procedures – but if you need to know which piston to order for a 168 CID diesel, this is the source.

Alternator and Starter: Electrical Component Locators

Alternator assembly (page 36) and starter motor assembly (page 37) show the exact Ford part numbers for the charging and starting systems. The tachometer drive assembly (page 38) and thermostart assembly (page 24) are included – thermostart is the cold-start aid on these diesels. If you’re chasing an intermittent no-crank on an SSD-437, the starter section helps you identify whether you need the drive end housing or the solenoid separately. That beats replacing the whole starter assembly because the parts counter couldn’t look up a brush holder.

Why This OEM Parts Catalog Matters

Aftermarket cross-reference databases are . . . optimistic. They’ll tell you a Champion part fits a Ford engine, but the bolt holes might be a quarter-inch off. This catalog is the original Ford publication – it’s the same document that Ford Power Products distributors used before the internet. The illustration style is old-school line drawings, but every reference number links to a Ford part number. If you’re maintaining industrial equipment, irrigation pumps, or generator sets that use these engines, you need the factory part callouts. Don’t trust a third-party parts list that might have been compiled by someone who never torqued a head bolt in their life.

Gasoline Engine Parts Catalog covers the smaller gas version, Ford Power Products BSD-444/444T Parts List handles the turbo diesel siblings, and Ford Power Products CSG-649 300 C.I.D.

FAQ

Can I use this catalog to order parts for an LSG-423 gasoline engine?

Yes – the catalog explicitly includes the LSG-423 4-cylinder gasoline engine on page 3 (engine identification table). The part numbers and illustrations cover both gasoline and diesel models listed in the title.

How do I read the year symbols in the parts list?

The symbols are explained on page 2: a single year means the part was used from that year onward; two years separated by a slash (e.g., 72/75) means the part was used only between those years; a year followed by a slash (e.g., 75/) means the part is still in current production at the time of printing. Match the year range of your engine’s serial number to the column to get the correct part.
