Dynapac LF90 Parts Catalog – 44 Pages of Factory Spare Part Listings

If you’re ordering parts for a Dynapac LF90 plate compactor without this catalog, you’re guessing. I’ve seen guys slap on aftermarket junk and then wonder why the machine won’t hold compaction. This 44-page factory Parts Catalog is what Dynapac ships to its dealers. It’s the difference between getting the right bearing and holding a handful of wrong-sized washers. Every part number in here came from the same engineers who built the machine. No aftermarket translations, no guesswork.

Spare Parts Ordering: The Six Pieces of Information You Must Have

Page 3 of this catalog lists exactly what Dynapac expects when you call for parts. Machine type, roller serial number, quantity, part number, part denomination, and dimensions if ordering by length. Miss one of those and you’ll wait an extra week for the wrong part. The catalog includes a serial number range – from 29011003 to 29011017 and 29011200 up – so you can cross-check before you order. I’ve had techs skip the serial number step and end up with a Honda GX120 gasket set when the machine had a Hatz 1B20. That’s a wasted afternoon.

Engine Coverage: Honda GX120 and Hatz 1B20

Your LF90 shipped with one of two engines – the Honda GX120 or the Hatz 1B20. This catalog lists spare parts for both. You’ll find separate sections with exploded views and corresponding part numbers. For the Honda, that covers cylinder heads, crankcases, recoil starters. For the Hatz, it includes injection pumps, fuel filters, and cylinder liners. If you’re rebuilding an engine, you need this catalog to pull the right part numbers – then refer to a service manual for torque specs and assembly procedures. Don’t mix them up.

How to Read the Parts List Structure (Group 3 as Example)

Page 4 shows the layout. Groups are numbered – Group 3 covers engine parts. Each group has a page number and a notes column. Items with a dot and moved indicator mean the part is listed in a different group. The text pages are structured with remarks at the bottom of the parts list. Once you understand that system, you can find any component in under a minute. The catalog uses standard Dynapac grouping – same logic across their compactor line, so if you later work on a Dynapac PL2000LS Parts Catalog (258 Pages) – OEM Factory Spec, you’ll already know the layout.

44 Pages of OEM Part Numbers – No Aftermarket Substitutions

Every part in this catalog carries a Dynapac original number. The manual lists all hardware, seals, filters, and wear parts specific to the LF90. I’ve seen too many machines fail because someone used a generic O-ring or a mismatched bolt. The thread pitch and material spec matter – especially on a vibratory plate that shakes at 100 Hz. Loose hardware comes back as a safety hazard. This catalog eliminates the guess. For more on Dynapac equipment, check the Dynapac official site. Understanding how parts catalogs fit into the broader equipment maintenance workflow is part of the Automotive Industry Overview – even though this is construction, the same discipline applies.

Audience: Who Needs This Catalog?

Home garage mechanics who maintain their own compactors, rental fleet operators, and any technician who wants to avoid the “close enough” trap. Beginners will benefit because the ordering guide on page 3 removes the fear of calling a dealer with the wrong info. Pros will appreciate having a single source for every part number rather than hunting through online forums. If you own an LF90 and don’t have this PDF in your toolbox, you’re working blind.

Frequently Asked Questions

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views only. For torque values and assembly procedures, you need the factory service manual.

Can I use this to rebuild the engine?

You can use it to identify every part you’ll need – pistons, rings, gaskets, bearings. But for disassembly steps, clearances, and torque sequences, you’ll require the engine service manual from Honda or Hatz. A mechanic who relies solely on a parts catalog for a rebuild is setting himself up for a leaky, loose engine. Don’t be that guy.

Stop ordering parts by eyeballing them. Download the Factory Manual from AutoRepairManuals – it’s the only OEM source for the LF90, and it saves you from making expensive mistakes on a machine that needs to work hard every day.
