SCAT TRAK 545 1999 Parts Catalog

If you’ve ever tried to order a part for a 545 using an aftermarket parts list, you know the headache of a wrong reference number leading to a week of downtime. I’ve been there. That’s why this 167-page factory parts catalog from 1999 is what you need on the bench. It’s the original SCAT TRAK 545 1999 Parts Catalog, not some photocopy of a photocopy. Every group – from the Engine to the Valve controls – is laid out with the same part numbers the assembly line used. Flip to the groups index on page 4 and you see exactly what’s inside: undercarriage frame, turning frame, engine/radiator, control valve, hydraulic and electric system, operator’s seat/hood/power controls, arms, decals/accessories, and tools. This is factory documentation, period.

Undercarriage Frame Group: Start at the Bottom

The undercarriage frame group is the foundation of the 545. On page 5 you get the full exploded view of the undercarriage – tracks, sprockets, rollers, and the frame itself. Each part is numbered clockwise starting from bottom left, exactly as the factory intended. The usage code tells you which serial number range that part fits. I’ve seen guys try to cross-reference aftermarket catalogs and end up with a roller that’s 10mm too wide. This manual kills that guesswork. You see the exact part number, the reference arrow, and whether it’s left or right hand. No reprints, no third-party edits – just the original Scat Trak print.

Engine and Radiator: Cooling and Power

The engine group covers the powerplant and cooling system. You get the radiator, fan, belts, and all mounting hardware. The parts are listed with quantities and the reference number matches the diagram. If you need a thermostat housing gasket, you look at the engine group, find the figure, and order that number. Aftermarket catalogs often lump engine parts together wrong – this separates them by actual physical location on the machine. The group index makes it fast: engine/radiator is group 03. Flip there, find the page, and you’re done.

Control Valve Section: Hydraulic Heartbeat

The control valve and mechanic controls group is where the hydraulic logic lives. Every spool, spring, and seal is exploded in the diagram. If you’ve got a stuck valve or a leaking seal, you need the exact part number from this section. Aftermarket parts suppliers sometimes substitute a generic spool that changes the metering. With the factory catalog, you order the same part that came off the line. The diagram includes arrows showing work direction – that matters when you’re assembling. Don’t rely on a third-party copy that might have a missing reference.

Does This Parts Catalog Cover the Hydraulic and Electric System?

Yes – the group labeled “HYDRAULIC AND ELECTRIC SYSTEM” is in there. It covers hoses, fittings, pumps, filters, and the wiring harness. But understand: this is a parts catalog, not a service manual. It gives you the part numbers for every connector, hose, and bracket, but it won’t tell you how to bleed the system or set pressures. For that you need the service manual. What this catalog does is let you order the correct hose assembly with the right end fittings, so you’re not splicing or using adapters. The electric side shows the entire harness layout with each connector part number. That alone can save you a whole afternoon on the phone with a supplier who doesn’t know the 545.

3 Reasons to Use the Factory Parts List Instead of Aftermarket

One: Aftermarket catalogs often use generic part descriptions that don’t match the actual casting numbers. You order a “hydraulic filter” and get one with the wrong thread pitch. This catalog gives you the exact factory filter part number. Two: The diagrams are photographically accurate line drawings, not re-drawn approximations. That matters when you’re trying to identify a bracket that’s been bent. Three: The usage codes tell you which serial number range each part fits. Scat Trak made running changes during production – a roller from early 1999 may not fit a late 1999 machine. Aftermarket catalogs ignore those codes. This manual doesn’t.

Understand the Parts Diagram Before You Order

Look at the diagram on page 5. Notice the arrow directions – the operator’s left and right are defined from the seat. The reference numbers are clockwise, bottom left to top. If you ignore that convention, you might order a right-hand track adjuster when you need left. The manual explains how to read it on page 2. Take three minutes to read that page – it’ll keep you from ordering the wrong part. I’ve seen apprentices skip it and then wonder why the sprocket doesn’t line up. Read the instructions. Use the factory diagram orientation.
