Rexworks SP-1000 Service Manual

If you’re wrenching on a Rexworks SP-1000 dual drum vibratory roller and you don’t have the factory service manual in your hand, you’re working blind. I’ve seen too many guys guess at torque specs on frame bolts and end up with leaks or worse, a cracked housing. This is the genuine OEM document – 152 pages of what the factory intended, not some aftermarket rewrite that missed half the details. That’s why I keep a copy on the bench.

Frame and Superstructure Coverage

The manual opens with the main frame – front (engine) and rear (fuel tank) – then moves through every superstructure component. You get the exact location of instruction decals and name plates, plus assembly details for the steering lock link, engine hood, side covers, operator’s platform, handrail, toolbox, battery tray, control console, instrument panel, travel control, seat mountings, hydraulic tank, and the sprinkler tank and water pump assemblies. Two separate sections cover sprinkler tanks before and after serial number GB-147. Drum scraper assemblies and spray bar assemblies are also included. For the ROPS assembly, the torque sequence is critical – the manual lays it out.

Power Unit: Engine and Fuel System

Engine mounts and their torque values are on page 46. The manual covers radiator and shroud, oil cooler, exhaust system, fuel system assembly, throttle connections at engine, air cleaner system, and the recommended service procedure for the engine air cleaner/element. Fuel system plumbing is shown with factory routing – not an aftermarket hack. Sending units for instruments are also detailed. If you’re chasing a fuel delivery issue, this section saves you from replacing parts that aren’t broken.

7 Systems Covered

This factory service manual breaks down the SP-1000 into seven major systems, each with its own diagnostic and repair procedures:

• Electrical Components: lights, battery, wiring diagram (main system), optional aedameter.
• Steering Components: articulating joint, hydraulic schematic, power steering cylinder, pump, Orbitrol control.
• Traction Drive Components: disc brake and mounting, daily test, emergency/parking brake procedure, brake bleeding, hydraulic motors and pump.
• Vibration Drive Components: wiring diagrams for standard and intermediate water spray, hydraulic schematic, vibration motor, tandem pump, frequency meter, isolators, drums.
• Drum Drive Planetary Gear Box: traction-only planetary gear.
• Pump Drive Assembly: drive gear box for two hydraulic pumps, controls and mounting.
• Hydraulic Systems: schematics for steering, traction, and vibration – all with component locations.

No guesswork.

Torque Values and Fluid Capacities

For the disc brake and mounting, the factory torque specs are on page 94. Engine mount bolts are on page 46. Hydraulic system schematics include pressure and flow data – you won’t find that in a generic repair guide. The manual also lists capacities for the hydraulic tank, sprinkler tank, and fuel tank. If you’re rebuilding the drum drive planetary gear box – similar to some Manual Transmission designs – the shim and bearing specs are in chapter 510-120. Don’t trust a third‑party print; use the OEM numbers.

Why OEM Beats Aftermarket Documentation

Aftermarket manuals for heavy equipment are notorious for omitting safety warnings and mislabeling wire colors. This is an original Rexworks print – the same one dealers use. The wiring diagram for the main system (page 104) and intermediate water spray system (page 106) are accurate. The hydraulic system schematics for steering, traction, and vibration show every valve and port. If you’ve ever chased a short using an aftermarket schematic, you know the difference. For smaller rollers, check the Rexworks SP-900 Vibratory Rollers Service Manual; for padfoot versions, the REXWORKS SP-848PD Padfoot Single Drum Vibratory Roller Service Manual; and the REXWORKS SP-910B Vibratory Roller Service Manual covers the 910B series. But for the SP-1000, stick with this factory release.

FAQ

Does this manual cover the SP-1000 serial number GB-147 and later?

Yes, it includes separate sections for sprinkler tank assemblies before and after that serial number.

What about the electrical system?

Covers lights, battery, wiring diagram for main system and intermediate water spray system, plus recommended maintenance for the 12V battery. The wiring diagrams (pages 104-106) show every connection – no guesswork. If you’ve ever chased a short in an aftermarket schematic, you’ll appreciate having the real thing. General theory on Manual Transmission systems won’t help here; this manual gives you the exact wire routing for the SP-1000.

So if you’re about to tear into the fuel system or troubleshoot a vibration drive issue, get the right document on your screen. Access the Factory Manual from AutoRepairManuals and have it open while you work. It’ll save you a headache.
