SCAT TRAK 535 1999 Parts Catalog

If you’re trying to rebuild a SCAT TRAK 535 mini excavator without the factory parts catalog, you’re burning time and cash. I’ve seen guys order the wrong valve block twice because they used a generic cross-reference. This 150-page OEM document from 1999 gives you the exact exploded views and part numbers the factory stamped on the line. No aftermarket reprints. No guesswork on thread grades or seal sizes. You need to know which part goes where inside the boom pivot? The group index gets you there before coffee gets cold.

UNDERCARRIAGE FRAME GROUP: Track Rollers and Sprockets

The first section of the SCAT TRAK 535 1999 Parts Catalog covers the undercarriage frame. Each roller, idler, and sprocket appears with a reference number and OEM part code. I’ve used this to match a worn track chain – the diagram shows left and right orientation as seen from the operator seat. Page 4 starts the group index. If your machine is throwing tracks because a bolt sheared off at the tensioner, you’ll find the exact fastener spec here. Don’t trust a parts store lookup: the factory catalog lists the correct shoulder bolt length and grade.

ENGINE – RADIATOR: Vernier Pulley and Thermostat Housing

Pages under the MOTORE – RADIATORE group break down the engine assembly. The 535 uses a specific radiator mount that differs from the 530 series. You’ll see the cooling fan shroud, alternator bracket, and the valve cover gasket part numbers. I’ve helped a DIYer replace a leaking water pump – he had the wrong gasket from an aftermarket kit. The catalog showed the correct part number because the pump casting changed mid-1999. Relying on memory? Not smart. Every valve seal, injector line, and thermostat housing cap is called out.

HYDRAULIC AND ELECTRIC SYSTEM: Solenoids and Wiring Harness

The hydraulic and electric system group is where most shade-tree mechanics screw up. The OEM catalog shows the pilot control valve, the main relief valve, and every solenoid coil with its resistance spec. I’ve used this to trace a no-swing issue – the parts catalog indicated a sub-plate gasket part number that wasn’t listed in any aftermarket database. Page 73? No, that’s for the arms group. For the hydraulic pump seal kit, you need to reference the group index. The wiring harness diagram uses factory connector shapes – you can match the pinouts to your machine’s year.

4 Reasons OEM Parts Catalogs Save You Money

1. Part numbers are cross-referenced to production date stamps.
2. Exploded views show fastener torque sequences (but the service manual has torques – this is a parts catalog).
3. Group index covers all ten categories: undercarriage, turning frame, engine-radiator, control valve, hydraulic/electric, operator’s seat, arms, decals, tools.
4. No “universal fit” guesswork – every component is specific to the 1999 model 535.

Control Valve – Mechanic Controls: Identifying Spools and Springs

Inside the DISTRIBUTORE – COMANDI MECCANICI group, you get the control valve breakdown. The 535 uses a two-spool auxiliary section. The catalog lists each spring, poppet, and O-ring dimension. If your machine drifts when you release the joystick, you can order the correct return spring kit. No need to disassemble blindly – the diagram shows the order of shims. I’ve seen techs stack washers because they didn’t have the OEM part numbers. Don’t be that guy.

Operator’s Seat – Hood – Power Controls: Cushion Mounts and Lock Levers

The POSTO GUIDA group includes seat cushion part numbers, foam densities, and hood latch spring specs. The 535 had a specific cab mount isolator that changed in late 1999. The catalog identifies the correct one. Also covers the power control lever assembly – each ball joint and boot is listed separately. Good for restoring a worn-out cab.

Arms Group: Boom, Stick, and Bucket Linkage

BRACCI section covers the boom and dipper arm. Each pin bushing, seal, and wear pad has a reference number. I’ve used this to order the right pin diameter for a 535 that had a sloppy pivot. The diagram shows the weld-on bucket ear dimensions – not for fabrication, but for ordering a new bucket with correct pin spacing. If you’re rebuilding the arm, you need this catalog to identify every seal in the bucket cylinder.

FAQ – SCAT TRAK 535 Parts Catalog

Does this catalog include torque specs for bolts?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views. Torque values are in the factory service manual. But the parts catalog tells you the correct bolt grade and thread pitch so you can find the right spec elsewhere.

How many pages is the 1999 catalog?

150 pages total. Group index on page 3. Every page is scanned from original factory print.

Can I use this for a 1998 SCAT TRAK 535?

You can, but verify compatibility. The catalog is for 1999 production. Some undercarriage components changed mid-1998. Check the group index for part number suffixes that indicate revision.

What about the hydraulic pump? Is the valve block covered?

Yes. The hydraulic and electric system group covers the entire hydraulic system, including the main control valve, pilot valve, and all section spools. Each cartridge and seal kit is listed separately. If you need the valve block casting number, it’s in the exploded diagram.
