Soosan SCS876, SCS877 2012 Parts Catalog

If you’ve ever tried to order a replacement seal for a Soosan crane and ended up with a part that didn’t fit because some aftermarket parts list used a different numbering system, you know the frustration. That’s exactly why I keep the factory Soosan SCS876, SCS877 2012 Parts Catalog on the bench. This isn’t a reprint or a third-party compilation. It’s the OEM document Soosan released in 2012 for the SCS876 and SCS877 hydraulic cranes. 148 pages of genuine part numbers, assembly breakdowns, and ordering instructions. Nothing else saves you that headache when a customer’s crane is down and you need the right part today.

148 Pages of Factory Part Listings

Every assembly on the crane is covered. The catalog splits the crane into major sections: CRANE ASS'Y (page 5), BOOM ASS'Y (page 11) with its telescopic cylinders in three stages, SWING POST ASS'Y (page 31), FRAME ASS'Y (page 43), PIPING ASS'Y (page 63), HOOK ASS'Y (page 81), STICKER ASS'Y (page 83), TOP SEAT ASS'Y (page 87), and MOUNTING ASS'Y (page 89). Each section includes an exploded-view drawing and a numbered parts list. Need the telescopic piping? Page 73 gives you the exact part numbers for hoses and fittings. No guessing which line goes where. The catalog shows the routing and the correct Soosan part.

Why OEM Matters for Parts Ordering

Aftermarket parts books often copy old numbers or change them without notice. The foreword in this catalog states it clearly: use only Soosan genuine parts. If you use another part and it fails, there is no compensation. That's not a threat – it's a fact. The crane industry, like the Automotive Industry Overview, runs on precise part numbers. One digit off and the seal doesn’t seat, the hose doesn’t reach, the pin doesn’t slide. With this catalog you get the numbers Soosan designed the crane around. For more context on why precision matters, see Automotive Industry Overview.< /p>

What Does Each Assembly Include?

Knowing what you’re looking at saves digging through unrelated sections. The boom assembly covers the main boom structure and the telescopic cylinder assemblies: 1st stage (page 19), 2nd stage (page 23), 3rd stage (page 27). The swing post assembly includes the winch reduction gear (page 33), the derrick cylinder (page 37), and the swing reduction set (page 39). Frame assembly has the rotary joint (page 45) and the operator’s valve stand set (page 49). Piping assembly splits into distributor, derrick, main winch, telescopic, swing, outrigger, and over-winding alarm piping – each with its own drawing. Hook assembly (page 81) lists the hook and its retention hardware. Sticker assembly (page 83) covers all decals and warning labels. Top seat and mounting assemblies finish the crane structure.

How to Order Parts Using This Catalog

Flip to the foreword (page 2). It tells you exactly what information to have ready: crane model (SCS876 or SCS877), part name, part serial number, quantity, and upper assembly name. The drawing shows a leader line with a number that matches the list. Each list gives the part number, description, and quantity per crane.
Take the derrick cylinder assembly (page 37). If you need the rod seal, find the cylinder section, note the part number, order that number from a Soosan dealer. That’s it. No cross-referencing three different catalogs.

One thing I tell every junior tech: never order a part from memory. Always have the catalog open. The part numbers change when Soosan improves a component. This 2012 edition includes those updates up to that year. If you’re working on a newer machine, you might need a later supplement, but for these models this is the definitive list.

Real-World Use Case: Avoiding a Costly Mistake

A shop I know once ordered a complete telescopic cylinder seal kit from an aftermarket supplier based on a model number alone. The kit arrived – wrong dimensions. The boom couldn’t extend under load. They had to pull the cylinder again, wait for the correct Soosan kit, and eat three hours of labor. With this catalog on the workbench, they would have seen the exact Soosan part number for the 2nd stage cylinder (page 23) and ordered the right kit the first time.

The same logic applies to outrigger piping (page 77), swing piping (page 75), and the over-winding alarm assembly (page 79). All the part numbers are there. All the quantities are for one crane. Use them as-is.

Frequently Asked Questions

Does this catalog cover both the SCS876 and SCS877?

Yes. The cover and contents are for both models side by side. Part numbers are listed per assembly.

Are torque specs included in this parts catalog?

No. This is a parts catalog, not a service manual. It lists part numbers and assemblies only. For torque values you need the separate Soosan service manual. But having the correct part numbers prevents buying the wrong fastener in the first place.

Can I use this to order parts for a 2013 or newer Soosan crane?

You can reference it, but Soosan may have changed part numbers after 2012. Use it as a starting point, then verify with the machine’s serial number and a current dealer.

What is the best way to keep this catalog usable in the shop?

Print the PDF and put it in a three-ring binder with sheet protectors. The drawings are detailed and you’ll want them open while standing at the crane. Digital is fine for research, but paper keeps grease off your phone.

The only way to guarantee you get the right part for a Soosan SCS876 or SCS877 is to have the factory document in front of you. Access the Factory Manual now.
