Tadano Z300-2 Parts Catalog – 111 Pages of Factory Part Numbers

Tadano Z300-2 Parts Catalog – 111 pages that save you from ordering the wrong seal and sitting on a dead crane for three days. I’ve seen guys swap out a pump on a Z300-2 using aftermarket cross-reference lists, then wonder why the pressure line leaks. That gasket they grabbed? Wrong thickness. This is the factory catalog, not a guess.

Hydraulic Pump Breakdown: Figures PB110-0099-00 and PB110-0130-02

Two full-page exploded views cover the L.13T and L.12L hydraulic pumps. Page 2 shows the pump assembly with every gasket, seal, and retaining ring keyed to a part number. You’ll see items like 316-323-2301L gasket and 466-507-30000 pump, with quantities per design (A through O). That “A B C D…” column tells you which variant uses that part. Miss that and you order the wrong revision. Page 3 lists alternate part numbers – STD, SL.3, SL.8TD – so you can spot a superseded part before you call the dealer.

Part Numbers: Why Factory Specs Matter

That aftermarket cross-reference book you obtained? It’ll tell you “seal, oil 22x36x7” but skip the offset for the SL.3 housing. Tadano prints the exact supersessions: for example, 310-120-10003 (STD) vs. 310-120-10005 (SL.3). One wrong digit and you’re bleeding hydraulic fluid. This catalog lists every combination: L.9STD, G.5STD, SL.7Y, etc. You need the right one for your crane’s build date. Look at the spare P/N rows on page 3 – they spell out alternatives for each sub-model.

3 Systems This Catalog Covers

Hydraulic pump assemblies (L.13T, L.12L, L57, 3B3) – gaskets, seals, plates. Seal and gasket kits – oil seals like 500-509-31510 and retainer rings like 466-621-02060. Part number cross-referencing – STD, SL.3, SL.8, L.5, and a dozen other suffix codes. Each component shows quantity per design variant, so you can order exactly what that specific machine needs.

Who Should Use This Catalog

If you’re a one-man shop maintaining a Z300-2 for a concrete outfit, this is your parts bible. Home garage enthusiasts who keep their own crane – don’t rely on online part finders that guess based on serial number ranges. This catalog is the same book the Tadano dealer parts counter uses. You’ll find every nut, gasket, and pump housing drawing. Pair it with the Tadano ATF 90G-4 2011 Parts Catalog for other models in your fleet, or the Tadano FAUN ATF 80-4 2002 Operators Manual – 779 Pages of Factory Data for operating procedures.

Source Authenticity: OEM Tadano vs Aftermarket

Any third-party parts catalog that claims to cover Tadano is a gamble. I’ve seen aftermarket lists drop the “-L” suffix from a gasket part number, sending you a part that doesn’t fit. This is an original factory-issued parts catalog – TM-Z300-2/P-05. The document is in Japanese and English, and the part numbers match the actual Tadano inventory system. No re-assigned reference numbers. You can take these numbers straight to the supplier. For broader context on why factory documentation matters in the Automotive Industry Overview, read the standards for OEM parts traceability. I also suggest these related documents: FAUN Part E Crane Testing Instructions for post-repair validation and Automotive Industry Overview for industry background.

Frequently Asked Questions

Does this catalog cover the entire Z300-2 crane?

Yes, it includes all major hydraulic components.

Are superseded part numbers included?

Yes. Page 3 lists STD, SL.3, SL.8, L.5, and other suffix variants for each part. For example, the hydraulic pump has eight different spare numbers depending on the model year design letter. You must match your crane’s design code (A–O) printed on the pump tag. If you order a 310-120-10003 (STD) but your machine requires a 310-120-10005 (SL.3), the mounting holes won’t align. The catalog also shows lower-level components like gaskets and seals for each pump variant, so you can rebuild rather than replace the whole assembly. This level of detail is what separates a factory manual from a generic parts list.

How many pages is the catalog?

111 pages of exploded diagrams and part tables.

Can I use this to identify parts for other Tadano models?

No – this is specific to the Z300-2. Hydraulic pump part numbers differ between the Z300-2 and the ATF series.
