SCAT TRAK 516, 520V 1999 Parts Catalog – OEM Factory Manual

Ordering wrong parts because you guessed at a number from a third-party list costs you time and money. The SCAT TRAK 516, 520V 1999 Parts Catalog gets you the exact OEM part number the first time. This is the same binder the dealership parts counter uses – 172 pages of exploded diagrams, factory callouts, and genuine part numbers. No aftermarket translations, no ambiguous cross-references. If you are maintaining a 516 or a 520V mini excavator, this catalog belongs on your bench.

Why a Parts Catalog Beats Any Aftermarket List

I tell every tech who works for me: trust the factory drawing, not a website that guesses. Aftermarket part sites often substitute a seal or bearing that *looks* right but has a different bore or material. This OEM catalog shows the exact part, its reference number, and where it lands in the assembly. Flip to page 2 – the manual explains how to read the diagrams: clockwise from bottom-left, left/right as seen from the operator seat. That alone eliminates the confusion that sends a $50 hydraulic line back because you ordered the wrong side.

What This 172-Page Catalog Covers

The catalog is organized by machine group. Each section has its own exploded view and parts list. Here are the major groups:

• 01 – Undercarriage Frame
• 02 – Turning Frame
• 03 – Engine-Radiator
• 04 – Control Valve – Mechanic Controls
• 05 – Hydraulic and Electric System
• 06 – Operator’s Seat – Hood – Power Controls
• 07 – Arms
• 08 – Decals – Accessories
• 09 – Tools

Every group shows the assembly breakdown. You find the part in the drawing, note the reference number, then locate it in the table with the official part number. For example, need a new idler for the undercarriage? Group 01, Fig. 010A (page 4) lists it with the correct bore size and seal spec.

Engine and Valve Components – Getting the Right Part

The Engine-Radiator group (03) covers the motor mount, cooling system, and related hardware. The Control Valve group (04) breaks down the main valve body, spools, and seals. If you are replacing a valve spool or a seal kit, this catalog gives you the factory number. Don’t guess a generic Viton O-ring – order the exact size and compound the engineers specified. The valve section includes both mechanical controls and the hydraulic manifold details.

Hydraulics and Electrical: Diagrams That Save a Saturday

Group 05 – Hydraulic and Electric System – covers the pump, lines, fittings, and wiring harness connectors. The exploded views show how each hose routes and what fitting goes where. You will also find the solenoid valves, switches, and relay positions. This is the kind of detail you need when a hydraulic line chafes and you need the exact replacement length and fitting orientation. Without it, you end up with a hose that is too short or has the wrong swivel angle. Automotive Industry Overview for context on why component standardization matters across construction equipment.

Using the Factory Diagram System on Page 2

Before you start ordering, read the instructions on page 2. It explains abbreviations (SX/left, OX/right, NF/not available alone), direction arrows, and how parts are numbered. The system is consistent across all groups. Once you understand it, you can navigate any page in the catalog. The manual also notes that parts marked NF are only sold as part of a larger unit – that saves you the frustration of ordering a seal that comes only with the whole hydraulic cylinder.

FAQ – Common Questions About This Parts Catalog

Will this catalog work for a SCAT TRAK 516 built after 1999?

This manual covers the 1999 model year. SCAT TRAK made production changes after that. Use it for 1999 machines and earlier serial numbers that match the original release. For later builds, get the corresponding year catalog.

Does the catalog include engine part numbers for the diesel motor?

Yes. Group 03 covers the engine and radiator assembly, including block, head, gaskets, injection system, and cooling components. Orders for internal engine parts require the full model number from your engine plate.

Is this a digital access or a bound book?

Digital PDF.

How do I read the diagrams if I don’t know Italian?

The catalog is bilingual – Italian and English. Group titles, callouts, and notes appear in both languages. The table of contents on page 3 lists groups in Italian and English side by side. The diagram abbreviations are explained on page 2 in English. You don’t need Italian to find parts. If you still get stuck, the illustrations are clear enough to match visually.

Stop wasting money on parts that don’t fit. Access the Factory Manual and get the exact numbers from the source that built your machine. It’s the difference between one trip to the parts counter and three.
