Dongyang Mechatronics SS3506 Parts Catalog – Factory Spare Parts List

I’m Mike Callahan, 28 years turning wrenches. When you order a part for a stick crane and get the wrong one, the machine sits. That downtime costs money. This factory parts catalog for the Dongyang Mechatronics SS3506 is the tool you need to get the right part the first time. It’s 134 pages of exploded diagrams and part numbers, direct from the manufacturer. No guesswork. The Korean and English bilingual layout means you cross-reference with the original plate on the crane. I’ve seen guys lose a day because they used a generic parts list that didn’t match revision letters. This catalog eliminates that.

What This Parts Catalog Actually Is

It’s an OEM spare parts list for the SS3506 stick crane built by Dongyang Mechatronics. Page 3 shows the owner registration form—that’s how you trace machine history. Page 4 and 5 have the Korean and English instructions for ordering parts: crane model, page number, indication number, part number and name, quantity, address. That’s it. No reprints, no aftermarket garbage. Every part number ties to an exploded view later in the catalog. If you’re rebuilding the slewing ring or replacing a control valve, you need the exact index number from the diagram. This catalog gives you that.

Parts Identification: Exploded Views and Part Numbers

Each major assembly—boom, base, outriggers, hydraulic cylinders—gets its own exploded illustration with numbered callouts. The part number table underneath lists the part number, description, quantity per assembly, and sometimes a note about superseded parts. Dongyang Mechatronics uses a consistent numbering system: the first four digits often indicate the assembly group. If you’ve got a worn-out pin or seal, look up the group number, find the callout, order that exact part. No cross-referencing third-party catalogs. The 134 pages cover the entire SS3506 stick crane, not just the base machine. Hydraulic pumps, valves, hoses, fittings—all there.

Ordering Parts the Right Way

Fill out the form on page 5 exactly. Crane model: SS3506. Page number and indication number (the figure reference). Part number and name. Quantity. Your name and address. Send that to the Dongyang Mechatronics A/S center. They’ll pull from the same catalog. If you skip the page number or indication number, they have to guess. I’ve had technicians call me after getting a cylinder seal kit for the wrong revision because they left off the indication number. This catalog gives you the system to avoid that.

Factory Parts vs. Aftermarket Reprints

Reprints look similar but miss details: revision letters, note boxes about supersession, and sometimes even the part number column alignments are off. I’ve seen a reprint where the callout numbers didn’t match the table. That’s a wasted order. The original Dongyang Mechatronics PDF has the exact layout from the Korean factory. You get the same document dealerships use. If you want to understand the Automotive Industry Overview context, that’s fine, but for this parts catalog, stick with the OEM scan. No aftermarket substitute gives you the original bilingual layout.

3 Critical Tips for Using This Catalog

First: always check the equipment serial number against the cover page—if your SS3506 is an early production run, some subgroups may differ. Second: cross-reference the part number with the quantity column; some parts are sold in kits that include multiple callouts. Third: when ordering from a dealer who handles Dongyang Mechatronics, give them the exact page and indication number. That speeds up supply chain. This catalog eliminates the back-and-forth. I’ve used it to pin down a 30-cent O-ring that kept a $12,000 crane off the job for two days. The cost of not having the right part number is high.

Frequently Asked Questions

Does this catalog include torque specs or maintenance intervals?

No. This is a parts catalog. It lists numbers and diagrams for ordering rotating parts, seals, pins, hoses, and structural pieces. For maintenance procedures and torque values, you need the factory service manual for the SS3506.

Is the catalog in English?

Bilingual: Korean and English on facing pages. The English is straightforward technical English. Even if you don’t read Korean, the diagrams and part numbers are universal.

How do I find a specific part number for the swivel joint?

Look in the table of contents for the hydraulic section. Each assembly has a figure number. Find the swivel joint figure, note the indication number, then match it to the part number table. If the figure isn’t labeled, scan the index—Dongyang groups parts by crane subsystem.
