Dynapac LH 300 Parts Catalog

Ever ordered a gasket for a plate compactor and ended up with the wrong part because the aftermarket catalog had a fuzzy drawing? I see that mistake every week. For the Dynapac LH 300, you need the OEM Parts Catalog – the one Metso Dynapac printed in Sweden, not some third-party reprint that swapped the fuel tank for a hydraulic reservoir. This 52-page document gives you exploded-view diagrams with real part numbers, not guesses. The Dynapac LH 300 Parts Catalog is the correct reference for identifying every bolt, seal, and bracket on the LH 300 forward and reverse plate compactor, whether it’s equipped with the Hatz 1B30 or the Honda GX270 engine.

Check the Binder Label on Page 3 First

Page 3 contains the binder label that tells you which serial number range this catalog covers. Ignore that label and you risk ordering a fuel tank that doesn’t fit your machine’s production run. The issue SLH300-1EN4 is valid from 2002-08. Earlier machines need a different catalog. Cross-check your machine’s serial number before you do anything else.

52 Pages of Factory Parts Diagrams

Every page in this catalog is a direct scan from the original binder. You get the same diagrams the Dynapac dealer uses when ordering parts. The table of contents splits the machine into logical groups – ground plate and frame, engine, power transmission, hydraulic system, electrical equipment, handle assembly, and decals. Each section shows the exploded view with callouts pointing to each component and a parts list with quantities. If you’ve ever tried to read an aftermarket parts list that renumbers everything, you know why this matters.

Engine: Hatz 1B30 and Honda GX270 Options

This catalog covers both engine variants in separate subsections. Page 16 starts the Engine section, with detailed breakdowns for the Hatz 1B30 (page 18) and the Honda GX270 (page 24). Each engine gets its own fuel tank drawing – page 20 for the Hatz, page 26 for the Honda. The engine installation pages (pages 22 and 28) show the mounting hardware, vibration isolators, and fasteners so you can order the correct bolt without digging through a bin of miscellaneous metric hardware. If you need the fuel system components, those pages are your source.

Transmission: Clutch Assembly Details

Power transmission starts on page 30. The clutch section is split the same way – Hatz 1B30 on page 32, Honda GX270 on page 34. You’ll see the drive plate, friction disc, release bearing, and all associated hardware. The exploded view shows the stacking order, which matters if you’re replacing the clutch and need the bearing depth correct. The catalog doesn’t give you torque specs (that’s a service manual job), but it gives you every part number so you can order the right friction disc the first time.

Hydraulic System and Electrical Equipment

The hydraulic section (page 36 onward) covers the hydraulic system separately for each engine – Hatz on page 40, Honda on page 38. The eccentric element section (page 12) shows the vibratory assembly. Electrical equipment starts on page 42, including wiring harness connectors and switches. If your LH 300 has a dead handle kill switch, you can find the exact switch part number on page 44. Handle section (page 46) includes the throttle control – old version on page 50, new version on page 52. That’s a common failure point; the plastic throttle bracket cracks, and this catalog gives you the metal bracket part number.

Source Validity: Why OEM Matters

I’ve had customers bring me aftermarket catalogs that show a generic drawing with a note like “oil filter – use equivalent.” That’s a problem when the hydraulic filter on a LH 300 has a specific bypass setting. This catalog gives you the genuine Dynapac part number. The binder label on page 3 tells you which serial numbers the catalog covers – you must check that before ordering. If your machine serial is outside the range, you need a different issue. The official Dynapac website may have updates, but this PDF is the factory file. For background on why OEM documentation matters in the Automotive Industry Overview, the same principles apply to construction equipment.

Dynapac LH 300 Parts Catalog: Audience Fit

This is for the equipment owner, the mechanic who actually turns wrenches on plate compactors, and the parts department that needs correct numbers. If you’re a DIY guy with a LH 300 that won’t start because the fuel line is leaking, you can find the fuel hose and clamps in the engine section. If you’re a rental yard mechanic replacing a cracked ground plate, the frame section has the plate assembly with grommet and bolt specifications. Do not use this to set valve clearances – that’s not its job. Pair it with the workshop manual for repair procedures. The Dynapac LH 300 Spare Parts Catalog is the parts side of the equation. Yes, that’s the same product – this one.

One more thing – the catalog is 52 pages, not reprints, not scanned copies. It’s the OEM file. If you’re tired of guessing part numbers because some aftermarket site used a drawing from a different model year, get this catalog and stop wasting time on returns.

FAQ

Does this manual include torque specifications?

No. This is a parts catalog. Torque specs are in the workshop manual.

Can I identify the fuel tank for the Honda GX270 engine?

Yes, page 26 shows the fuel tank assembly for the Honda GX270 option. The catalog breaks down each component with part numbers, quantities, and illustrations. If your machine has the Hatz 1B30, refer to page 20 for the fuel tank. But you must check the serial number range on page 3 first – that binder label tells you exactly which production run this catalog covers. Ordering parts from the wrong issue means you get the wrong tank, even if the picture looks right. I’ve seen mechanics order a Honda fuel tank for an early Hatz machine and wonder why the mounting bracket doesn’t line up. Don’t skip that step.

What does the Power Transmission section cover?

The Power Transmission section starting on page 30 covers the clutch assemblies for both the Hatz 1B30 and Honda GX270. It is split into two sub-sections: Clutch Hatz 1B30 on page 32 and Clutch Honda GX270 on page 34. Each shows the drive plate, friction disc, and release bearing with factory part numbers.

Is this catalog compatible with the LH 700?

This catalog is specific to the LH 300. The LH 700 uses a different frame and hydraulic system. If you need the workshop manual covering both models, look for the DYNAPAC LH 300 LH 700 2001 Workshop Manual – but for parts, stick to the LH 300 catalog.

You know what it’s like when a part doesn’t fit and you’ve got the machine torn apart. Don’t waste a day chasing wrong numbers. Access the Factory Manual and get the correct part numbers for your Dynapac LH 300.
