Weidemann Perkins 404D-22 Engine Spare Parts Catalog (de, fr, en)

Out on farms, yards, and construction sites, these Weidemann machines run their Perkins 404D-22 engines hard in dust, mud, and cold starts. This parts catalog is what I pull out when I’m rebuilding or swapping anything on the engine and need to be sure I’m ordering the exact right bits. If, for example, a loader comes in with low oil pressure and I end up pulling the bottom end apart, I’ll use this book to match the correct gaskets, seals, and fasteners so everything goes back together once—without surprises.

Applications & Use Cases

• Trace assemblies from the bare block up, so you can see every washer, seal, and bracket that belongs in a given area.
• Isolate superseded parts when there are multiple versions of the same component and avoid ordering an outdated or wrong revision.
• Verify small hardware—clips, O-rings, bushings—that are easy to overlook during a teardown.
• Confirm correct variants of pumps, manifolds, and covers when the engine has different options across machines.
• Plan a rebuild by printing the relevant exploded views and laying them out on the bench next to the engine.

FAQ

Q: Can I use this catalog on a tablet in the workshop?

A: Yes, it’s practical on a tablet; you can zoom into the exploded views to read part numbers and details clearly.

Q: Is it worth printing pages, or should I keep it digital only?

A: Many techs keep it digital but print the specific assemblies they’re working on, so those pages can get dirty without risking the whole catalog.

Safety Note

Always isolate the machine, follow lockout procedures, and verify the engine cannot start before removing or installing any parts.
