Dynapac LG300 Parts Catalog – 75 Pages of OEM Factory Specs

If you’re ordering parts for a Dynapac LG300 Parts Catalog and guessing which gasket or bolt goes where, you’re burning money and downtime. I’ve seen guys pull a part number off a worn-out casting, order it, then stare at a box that doesn’t match. That stops the minute you open this factory catalog. 75 pages of OEM breakdowns, no third-party redraws, no translation errors. Page 4 tells you exactly how to order—machine type, serial number, quantity, part number, denomination, and dimensions if you’re buying by the foot. That’s the kind of detail that keeps your job moving instead of deadlined waiting for the wrong piece.

LG300 Parts Breakdown Accuracy

Every exploded view in this catalog came from Dynapac’s own engineering files. The Hatz 1B30 and Honda GX270 engine sections are separate, with their own part number ranges. You don’t get a generic engine illustration that sort-of matches. You get the exact mounting plate, belt guard, and exciter assembly with the correct hardware callouts. Need a replacement base plate? The drawing shows the plate with weld seam locations and bolt holes dimensions. No guessing which revision fits your serial number range.

Engine Variants: Hatz 1B30 and Honda GX270

Two engine options, two completely different parts lists. The catalog splits them clearly. If you’re swapping a Hatz for a Honda, you need to know which flywheel matches—this catalog has that data. One guy in my shop tried to fit a Honda carb onto a Hatz block last month because “they looked the same.” Cost him a weekend. Don’t be that guy. The OEM part numbers are right there. Order the correct intake gasket the first time.

3 Things You Need Before Ordering Parts

First, the machine serial number. That’s stamped on the frame tag. Second, the part number from this catalog—not the one you scratched off with a wire brush. Third, the quantity. The manual includes a note on page 4: “Dimensions when ordering per length.” That’s for things like hydraulic hoses or seal stock. You measure in inches, you give that length, you get what fits. Miss one of those three, and you’re playing telephone with the parts counter.

Is This Manual for the Shop or the Field?

Both. In the shop, you use it to cross-reference old part numbers against superseded ones. In the field, you pull it up on a tablet to identify which bolt pack you need for the handlebar assembly. It’s not a repair manual—there are no adjustment specs or torque values. But if you’re the guy who has to track down a replacement exciter housing or a throttle cable for an LG300, this catalog saves you from tearing down the whole machine just to read a bearing number. Keep it in your tool crib, keep your parts bins organized.

OEM vs Aftermarket: Why This 75-Page Catalog Matters

Aftermarket catalogs take shortcuts. They compress ten drawings into one and use generic numbering. Not this one. This is a direct scan of the Dynapac factory publication—serial number valid from 13000001, published catalogue issue SLG300-2EN1, dated 2006–06. The original PDF is 75 pages of uncompromised OEM data. You get the same page the dealer uses. No redrawn blobs, no “equivalent” numbers that don’t cross. If you’ve ever ordered a part for a Hatz 1B30 and got a Honda part in the box, you understand why original documentation is worth the byte space.
