TCM PPU340 Parts Catalog – 130 Pages of Factory-Grade Component Data

If you’ve ever ordered a replacement gasket or a hydraulic fitting based on a picture on a screen and ended up with a part that doesn’t seat, you already know the kind of headache I’m talking about. A parts catalog is supposed to kill that guesswork. The TCM PPU340 Parts Catalog does exactly that — but only if you’re using the original factory print, not some third-party rehash that renumbers parts and drops crucial notes. I’ve got 28 years in the bay, and I’ve seen more misordered pistons and wrong seals than I care to count. This manual puts the real data in your hands: 130 pages of factory-assigned part numbers, exploded diagrams, and application tables that track engine number ranges down to the month of manufacture.

The catalog breaks down the PPU340 Nissan gasoline engine used in TCM forklifts like the FG35N5 and FG40N5. You get the exact same documentation that TCM (Toyo Umpanki Co., Ltd.) issued to dealers and service centers. Every bolt, every bearing, every fuel system component is listed with its original part number, the engine model it fits, and the revision code that tells you whether it supersedes an older piece. That last bit alone saves you from buying a part that was replaced ten years ago and no longer exists as a separate item.

How the Parts Manual Organizes Data

Flip to the “HOW TO USE PARTS MANUAL” section (starts after the cover). The manual uses a five-field system: Model code, Fig. number, Section, Revision history code, and Item numbers. Each illustrated figure groups related components — say, the cylinder block assembly or the carburetor. Item numbers in the illustration correspond directly to the numbered list below it. You look for the part number in the Parts No. column, check the quantity (Req’d column), and note any remarks like “A” for assembly or “*” for set / kit component. This is the same structure TCM has used for decades, and it’s dead reliable.

One thing I respect: the manual flags parts that are not sold separately with the [§] symbol. That means if you see that next to a piston pin, you don’t order just the pin — you buy the whole piston assembly. Aftermarket catalogs love to list every widget as a standalone item, then you get a box with half the parts missing. This OE Catalog saves you that frustration.

Engine Number Ranges: Get the Right Parts

Page 5 of the catalog spells out applicable engine numbers. For example, engines numbered up to E513635 (built through August 1975) use one set of parts. Engines from 513636 onward (September 1975 and later) use different components in some areas. The manual gives you the specific cutoff numbers so you can match your engine serial to the correct revision. If your forklift was built in late ’75, ordering parts intended for early production can land you a block that doesn’t accept the new water pump or a crankshaft with different journal sizes. This is why you need the factory manual — it records those split points.

Parts Numbering and Abbreviations

The catalog uses a clean table system. Columns: Fig. number, Item No., Parts No., Description, Req’d, Remarks. Abbreviations like “A” for Assembly and “*” for set component appear in the Remarks column. The “+” symbol marks parts that are not illustrated (usually hardware like bolts or washers that go with an assembly). Every part number is a genuine TCM / Nissan factory number. If you walk into a dealer with that number, they’ll pull the exact part off the shelf. I’ve tested this on a dozen different TCM models — the numbers match what’s in the system.

The manual also includes a section for revision history codes. When TCM updates a part — say the carburetor flange gasket gets a thicker material — the old part number gets a suffix change or a new number entirely. The revision code column tells you which version applies to your engine. You don’t have to guess whether that new gasket will leak because you’re buying the latest spec.

Who Needs This Manual

Anyone maintaining a TCM PPU340-powered forklift — whether you run a warehouse fleet or own one machine in a hobby shop — will get concrete benefit from this catalog. Parts counter people hate looking up stuff for old Japanese equipment if you don’t have a part number. Hand them this manual’s page, and they can order blind. For DIY shop owners: if you’re rebuilding the top end on a PPU340, you need the correct valve guide seals and keepers. This catalog shows you the parts breakdown and the quantities. Not having it means you either buy an aftermarket kit that may or may not have the right bits or you spend an hour cross-referencing vague online listings. That’s lost time and potential misfit.

Related catalogs in the same family cover larger engines: TCM FD60Z8 FD70Z8 FD80Z8 FD100Z8 Parts Catalog – 650 Pages, TCM Isuzu-4218A-E Parts Catalog – 478 Pages OEM Factory Manual, and TCM 125B Parts Catalog – 244-Page OEM Factory Manual. Each follows the same factory format, so you can cross-reference if you’re maintaining multiple TCM models.

Why Factory Documentation Beats Aftermarket

Aftermarket parts catalogs often photocopy original data, then re-number parts to fit their own inventory system. That creates confusion when you try to order from a different supplier. They also leave out revision notes and engine number cutoffs because they don’t want to maintain detailed historical data. The TCM PPU340 Parts Catalog is a direct scan of the official TCM publication. Every page is exactly as issued by Toyo Umpanki Co., Ltd. You’re getting the same info a TCM dealer service manager used in the 1970s. That’s your insurance against ordering a part that doesn’t belong on your engine.

Frequently Asked Questions

Does this manual include torque specs or repair procedures?

No. This is a parts catalog only. It contains part numbers, exploded views, quantities, and application data. For service procedures, you need the separate TCM PPU340 Service Manual.

Will the part numbers still be valid for current ordering from Nissan or TCM dealers?

Most part numbers remain active, especially for engine internal components and gaskets. TCM and Nissan have superseded a few numbers over the decades, but the catalog lists the original number and any revision code. Your dealer can check supercessions from the base number. The manual gives you the correct starting point — far better than walking in with a vague description like “the little brass fitting near the carb.”

When you need replacement parts for a TCM PPU340 engine, you save time and cut error by working from the factory document. Access the Factory Manual from AutoRepairManuals and keep it on your workbench — either printed or on a tablet. You’ll pull the right part number every time.
