Dynapac LG400 Parts Catalog – What You Get When You Stop Guessing at Part Numbers

I have watched guys order the wrong hydraulic filter three times in a row because they used a generic cross-reference chart. That costs money and downtime. The Dynapac LG400 Parts Catalog is the only document that will get you the exact factory part number for every component on that vibratory plate compactor. This is a 66-page OEM spare parts catalogue, printed by Dynapac themselves, not a photocopy of a third-party scan. If you maintain an LG400 – whether it’s the Honda GX390 or the Lombardini 15LD 440 engine variant – you need this on your bench, not a PDF you found on a forum.

What This Parts Catalog Actually Covers

This document is broken down by groups – each group corresponds to a major assembly on the machine. The catalogue lists every nut, bolt, seal, bearing, and casting with its factory part number. You get exploded-view illustrations that show exactly how each piece goes together. The group numbers and page references let you jump straight to the section you need. The manual opens with a spare parts ordering procedure (page 4) that tells you exactly what information to have ready: machine type, serial number, quantity, part number, and denomination. Skip that step and you will get the wrong part. I have seen it happen.

Ordering Spare Parts: The Right Way

Page 4 of the catalogue lists the required information in six clear items. You need the roller serial number – that’s a stamped plate on the frame. You need the part number from the exploded diagram. Do not call your dealer and say “I need the throttle lever for a Dynapac LG400.” They will ask for the part number. The manual prints the part number next to each item in the illustration. If you order without it, you will wait a week for the wrong piece. The manufacturer Dynapac specifically designed this catalogue to eliminate that guesswork. Use it.

Engine Options: Honda GX390 and Lombardini 15LD 440

Two engine variants were offered on the LG400. The catalogue covers both. The front section identifies which engine is mounted based on the serial number break. That matters because the carburetor, air filter, and crankcase parts are different. One misordered gasket can leave the machine down for days. This manual shows the parts for both engines in separate group sections. Do not assume the Honda parts will fit the Lombardini – they will not. The exploded drawings make that clear.

66 Pages of Factory Specs – No Shrink Ray, No Reprint

66 pages does not sound like a lot until you realize every page is a dense group of illustrations and part numbers. There are no fluff pages. No safety disclaimers written in five languages taking up space. The first page is the title and serial number range. Page 2 is blank. Then it jumps straight into the spare parts catalogue. The manual is structured with text pages that explain the layout: a remarks column, a dot system for moved items, and group page references. It is not a repair manual – it is a parts identification book. You pair this with a service manual to do the actual work. That is how professionals keep equipment running. Automotive Industry Overview might give you context, but this catalogue gives you the part number.

Why OEM Documentation Matters for a Parts Catalog

I have had aftermarket parts suppliers tell me their “equivalent” part number is the same as the OEM. Then I install it and it does not fit because the thread pitch is off by half a millimeter. The Dynapac LG400 Parts Catalog comes from the same source that built the machine. Every part number in here was used on the assembly line. When you call your dealer and read the number off this catalogue, they will ship the correct piece. No returns. No waiting. That is the difference between OEM and a third-party database built from guesswork. Do not waste your time on cross-reference websites.

Frequently Asked Questions

Does this parts catalog cover the entire LG400 machine?

Yes. The catalogue includes all major assemblies: engine, baseplate, exciter, handle, and transport kit. Every nut and bolt is listed by group. If it is on the machine, the part number is here.

Can I use this catalog to repair the engine?

No – this is a parts catalog, not a service manual. You need the engine manufacturer’s service manual for overhaul procedures. This catalogue exists to identify and order the correct replacement parts.

What serial numbers does this issue apply to?

Valid from serial number 34000001 onward. Check the serial plate on your LG400 before ordering. If your machine is older, this catalogue may not cover every earlier part. Dynapac updates catalogues when they change components.

Why do I need the serial number to order parts?

Because Dynapac made running changes. The same model year may have different bearings or seals depending on the production run. Giving the serial number ensures you get the part that matches your actual machine. Always include it when ordering from the dealer.

Access the Factory Manual. Stop wasting time with internet cross-references. The Dynapac LG400 Parts Catalog gives you the exact OEM part numbers you need to keep that plate compactor running. Get the 66-page PDF, print the exploded views, and tape them above your workbench. You will never order the wrong part again.
