Description

Donaldson 05, DA220, 15Graylift, H20, AH05 Technical Manual

You’ve got a Komatsu lift truck with a dead air filter or a leaking lube filter, and the parts counter hands you a generic box that doesn’t match the OE number. Now you’re second-guessing the thread pitch, the bypass valve setting, whether the element seals right. That’s a waste of labor and a safety risk if the filter fails. This Donaldson Technical Manual for models 05, DA220, 15Graylift, H20, and AH05 gives you the factory cross-reference in 17 pages – no guesswork, no aftermarket part number hunting.

Vehicle Cards: What They Actually Tell You

Page 2 opens with the “VEHICLE CARDS – ALL APPLICATIONS” header. That’s where you find the layout: Qty, Description, OE Number, Donaldson Note, and Serial Number. Every entry is a direct line from the Komatsu OEM part to the Donaldson filter that replaces it. For example, the 05 Komatsu with Isuzu DA220 engine lists air primary filter 37Z02AF931 cross to Donaldson P181050. That’s a axial seal air filter – critical detail for fitment. The manual doesn’t sugarcoat; it’s a table of hard data.

Komatsu Lift Truck Cross-Reference: Engine to Filter

The OCR excerpt shows the core structure: each model – 05, DA220, 15Graylift, H20, AH05 – gets its own section under the KOMATSU LIFTTRUCK heading. You’ll see the engine family (Isuzu DA220, Nissan H20, etc.) and the serial number range. Then the Donaldson part numbers for air primary, fuel spin-on, lube cartridge, or lube spin-on. For the AH05 with Isuzu DA220, you get three filters: air primary P522449, fuel primary P550057, and lube cartridge P550018. That’s the level of detail you need to order the right part once.

Does This Manual Cover the Fuel System?

Yes, where applicable. The H20 model with Nissan D11 lists a fuel filter (1640350000) but no Donaldson number – likely a superseded or non-Donaldson application. The AH05 and 05 models get fuel spin-on filters with Donaldson P550057. Lube filters are covered for most models. Air filters are the primary focus. If you need a full fuel system rebuild, this isn’t that manual – it’s a filter cross-reference. But for filter swaps, it’s the only sheet you need on the workbench.

Why OEM Donaldson Cross-Reference Beats a Parts Store Guess

Aftermarket catalogs sometimes group multiple OE numbers under one filter that doesn’t match the bypass pressure or seal type. Donaldson’s own vehicle cards are the original data – they’re the same sheets Donaldson distributors use. The manual lists the exact OE number (e.g., 37Z02AF931 for air primary) and the Donaldson replacement (P181050). No third-party interpretation. If you’re replacing a filter on a 15Graylift or any other Komatsu model, you match the OE number printed on the old filter against this list. End of story.

17 Pages of Filter Specs – What’s Inside

Every page is a continuation of the vehicle card tables. The document covers multiple Komatsu models beyond the 05, DA220, 15Graylift, H20, and AH05 – including DX20, AX, EX, FD10, FD10L, FD10N, FD14, and more. The cross-reference report follows the same format. For a shop that works on several Komatsu forklifts, this one manual covers the filter application for all of them. Page 1 is the title page; the real data starts on page 2. That’s where you live.

Can I use this manual to rebuild the engine on my Komatsu forklift?

No. This is a filter cross-reference, not a repair manual. It tells you which Donaldson filter replaces the OE part – nothing more.

How do I confirm the correct filter for a serial number not listed in the manual?

If your Komatsu lift truck’s serial number falls outside the range shown (e.g., serial N°: (kW – hp) – (00/00 =>)), the manual still lists the filters by engine model. For example, the H20 model uses Nissan D11 or J15 engines. Match your engine model to the Donaldson part numbers given. If your engine is not listed, you need a different manual – check the Donaldson Freightliner M2, Ford, Navistar, GM 2009 Technical Manual for medium-duty trucks, or the Drogobych Crane КТА-16, КТА-25, КТА-28 2004 Installation Manual for a completely different application. For manual transmission work, see Manual Transmission and Manual Transmission resources. This Donaldson manual is specific to Komatsu forklifts with the engines covered.

If you’re rebuilding a forklift, you also need the engine and transmission manuals. Look at the Injectocean Diablo, Murciélago, Defender, Discovery, Freelander Technical Manual for a different brand. But for filter replacement on the 05, DA220, 15Graylift, H20, or AH05, this Donaldson vehicle card is the final word.

Access the Factory Manual and stop guessing which filter goes where. You’ll have the same information Donaldson gives their own dealers – no aftermarket interpretation, no missing part numbers.
