Weidemann Perkins 403D-11 Engine Spare Parts Catalog (ru, pl, en)

The Perkins 403D-11 in a Weidemann is a small industrial diesel that spends its life in tight barn aisles, muddy yards, and construction sites, running loaders, handlers, and similar machines. This spare parts catalog is what I use when I’m rebuilding that engine or chasing damage after a belt snaps or a hose rubs through. It lets me break the engine down on paper first, so I can match every gasket, seal, and bracket before I touch a wrench. For example, if a front crank seal is leaking, this catalog helps me confirm the exact seal design and any related hardware so I don’t have to tear it apart twice.

Applications & Use Cases

• Identify the correct revision of brackets, pulleys, and covers when Perkins or Weidemann changed designs mid-production.
• Trace exploded views of the fuel, cooling, and air systems to spot small O-rings, sleeves, and clips that are easy to overlook.
• Verify fasteners, washers, and bushings so you order the full set and avoid reusing worn hardware.
• Compare similar part variants (e.g., different sensor or alternator options) to avoid wrong deliveries.
• Plan a full overhaul by listing every seal kit and gasket you’ll disturb during the job.

FAQ

Q: Can I use this catalog on a tablet at the machine?

A: Yes, it’s practical to zoom into the exploded diagrams on a tablet, which makes it easier to match parts while you’re standing at the engine.

Q: Is it worth printing sections of this catalog?

A: Many techs print just the relevant assemblies so they can mark part numbers, circle replaced items, and keep a clean copy in the job folder.

Safety Note

Always isolate the machine, follow lockout/tagout procedures, and let the engine cool fully before using this catalog to guide any work.
