If you cannot find the PDF, your local Mitsubishi Forklift or Fuso truck dealer can still order microfiche or printed copies, though this costs significantly more ($150+).
Before you search for the PDF, verify that you have the correct engine. The 4D32 is often confused with the 4D31 or 4D34. Here are the standard specs you will find in the manual:
| Specification | Detail | | --- | --- | | Engine Type | Inline 4-cylinder, water-cooled, 4-stroke diesel | | Displacement | 3.56 Liters (3,560 cc) | | Bore x Stroke | 102 mm x 108 mm | | Compression Ratio | 17.5 : 1 | | Firing Order | 1-3-4-2 | | Injection Pump | Bosch Inline (A-type) or Mini-pump | | Aspiration | Naturally aspirated (Non-turbo on standard models) | | Valve Clearance (Cold) | Intake: 0.25mm / Exhaust: 0.30mm |
Always verify these numbers with your specific manual, as revisions exist for different chassis codes.
Do not rely on a single 10-page “data sheet” claiming to be the full manual. The complete Mitsubishi 4D32 Engine Workshop Manual is typically 250–350 pages long, with fold-out schematics. If you cannot locate a free legitimate PDF, consider purchasing a dealer-reproduced manual – it will pay for itself by preventing a mis-timed engine on the first rebuild.
If you specify whether you need the manual for a vehicle (like Mitsubishi Canter) or an industrial engine (bare power unit), I can help refine the search or suggest equivalent cross-reference manuals (e.g., 4D30/4D34 share many 4D32 procedures).

Do not attempt to remove the injection pump without reading Section 5 of the manual. The pump drive gear is a taper fit; prying on the housing will crack the gear case.
