Rexworks SP-1100B Service Manual – No Aftermarket Guessing

If you’ve ever tried to rebuild a hydraulic vibratory roller with a third-party manual, you know the pain. Wrong torque values for the damper pulley. A wiring diagram missing the magnetic pickup circuit. A brake system schematic that doesn’t match the actual machine. That’s why I only trust OEM documentation when I’m inside something heavy. The Rexworks SP-1100B Service Manual is a 69-page factory book that came from Rexworks themselves, not some aftermarket reprint house. It covers the SP-1100B dual drum vibratory roller (R 183) with every exploded view, torque spec, and hydraulic routing you need to do the job once.

One look at the index tells you this isn’t generic. The manual dedicates pages 9 through 14 to the power unit option, mounting, air cleaner, muffler, and power steering pump with belts and sheaves. That’s the kind of detail you need when the isolator pad cracks and you’re trying to figure out which Donaldson element goes in the horizontal air cleaner. Pages 15–17 cover the frames, guards, engine housing, hydraulic and fuel tanks, electric control console, and operator seat. The Engine section includes the John Deere model 06359D (Spec. #FC-16089) with part numbers like the damper assembly AT30428 and the 7-blade 18″ fan AT35158. No “refer to generic engine manual” nonsense – it’s all here.

Wiring Diagram and Magnetic Pickups (Pages 25–28A)

The Wiring section is worth the price alone. Page 25 through 28A gives you the complete wiring diagram for the power unit, magnetic pickups, speedometer, amplitude control, and hydrotransmission valve. That magnetic pickup circuit is the first thing to fail when the vibrator amplitude stops working – the manual shows exactly how to test the solenoid bracket and the Cole Hersee #24037 fuel pump shutoff solenoid. You also get wire routing for the solenoid bracket and the full wiring harness reference. If you’re chasing an electrical gremlin in the control console, this is where you stop guessing.

Hydraulic Systems: Steering, Vibrator, Propulsion (Pages 30–44)

Three separate hydraulic systems get their own chapters. Pages 30–35 cover the power steering hydraulic system with the Vickers VTM42-60-75-15-MD-R1-14 pump. Pages 36–37 deal with the vibrator hydraulic system. Pages 41–44 handle the propulsion hydraulic system. Each one includes hose routing, pump mounting brackets, and the exact matched set of two “V” belts for the steering pump. The Gear Case Assembly – Roll Drive (pages 50–53) and Hydraulic Motor – Traction Drive (pages 54–56) give you the internal seals and bearing numbers so you don’t order the wrong kit.

Brake System and Vibratory Roll Assembly (Pages 58–65)

Brake work on a roller means safety first. Pages 58–60 cover the brake system with the exact cable routing and adjustment specs. The vibratory roll assembly (pages 61–65) shows the eccentric weights, drum seals, and the water tank components (pages 66–67.15) including the spray bars and gauges. The Water Tank section includes the pump, strainer piping, and hose routing for wet compaction – a common failure point on these machines. If you’ve ever had a spray bar plug up because the strainer was wrong, you’ll appreciate the factory part numbers.

Valve and Control Override: When the Operator Panel Goes Dark

The operator controls chapter (pages 15–17) covers the forward/reverse, vibration override, and power steering valve. That vibration override is a unique Rexworks feature – it lets the operator disable vibration for transport. The manual explains the hydrotransmission valve adjustment so you don’t accidentally override the safety cutoff. Combined with the instruction plates and warning decals locations (pages 67.1–67.15), you can verify every control cable is attached to the right bracket. The throttle bracket, cable clamp with shim, and rod end are all illustrated with Rexworks part numbers.

Fuel System and Engine Accessories

The Fuel section is baked into the power unit chapter. The manual includes the fuel pump shutoff solenoid, transfer pump (ref. only – see engine parts book), and the complete radiator and oil cooler assembly. Pages 9–14 show the radiator hoses (2″ I.D. and 2¼” I.D.), the hydraulic pump driven sheave, and the grade 5 drilled cap screw for the pulley. If you’re swapping the John Deere engine, you get the front and rear engine brackets, damper, and the soft iron wire (16 ga. x 2″ lg.) for safety-wiring the cap screw. That’s not something you’ll find in a $20 reprint.

OEM documentation matters because aftermarket manuals skip torque values. This manual doesn’t. Every cap screw – from the 1/4″ x 3/4″ H.C.-H.T. cap screw to the 3/8″ x 1″ zinc plated bolt – has a grade specification and lock washer requirement. The isolator pad, muffler clamps, and hose clamps are all called out by part number. If you’ve ever had a reprint where the page numbers don’t match the binder, you’ll appreciate that this is the original factory file – 69 pages, scanned from the actual Rexworks binder, not a copy of a copy.

Who Needs This Manual?

Whether you’re a rental yard mechanic, a compaction contractor, or a home garage enthusiast who bought a surplus SP-1100B at auction, this manual covers everything from the water tank pump to the brake system. The hydraulic routing alone will save you from chasing leaks for hours. If you’re also working on other Rexworks rollers, check the Rexworks SP-1000 Service Manual – OEM Factory Specs for Dual Drum Roller or the Rexworks SP-900 1977 Service Manual – Factory Specs for Vibratory Roller or the Rexworks SP-848PD Service Manual – Factory Specs for Padfoot Roller. For general knowledge on different transmission types, Wikipedia has a decent article on Manual Transmission and Manual Transmission – but for the hydrostatic drive in the SP-1100B, stick with the factory book.

The manual is 69 pages. It’s not a 500-page all-model soup. You get exactly what the Rexworks dealer tech had on the shelf in 1980. No extra fluff. No third-party interpretation. If you need the charge pressure for the propulsion pump, page 41. If you’re rebuilding the vibratory roll, page 61. Access the Factory Manual and get the job done right.

Does this manual cover both dual-drum and single-drum Rexworks rollers?

No. This is specifically for the SP-1100B dual-drum vibratory roller model R 183. For single-drum or other models, see the related Rexworks manuals listed above.

What engine is included in the manual?

The manual covers the John Deere model 06359D (Spec. #FC-16089) with full mounting brackets, damper, fan, radiator, and fuel shutoff solenoid. Engine internal rebuild specs are not included – those require the separate John Deere engine parts book.

Are torque specifications printed in the manual?

Yes. Every fastener callout includes the grade and lock washer. The mounting bracket cap screws, hydraulic pump sheave bolts, and damper assembly all have specific torque values referenced in the exploded views. The manual doesn’t list a generic torque chart – it gives you the exact spec for each bolt based on Rexworks engineering. For example, the grade 5 drilled cap screw on the steering pump adapter pulley has a note about safety-wiring with 16 ga. soft iron wire.

I have a later model SP-1100B with a different serial number range. Will this manual still apply?

The manual covers the SP-1100B dual drum roller (R 183) from the 1980 era. Rexworks issued updates via service bulletins. This manual includes the warning decal locations and instruction plates that were current at publication. If your machine has a newer wiring harness or a different air cleaner mounting, you may need a supplemental bulletin. Check the serial number against the manual’s illustration – the parts list calls out part numbers that may have superseded. Use the manual as the baseline, then verify any discrepancies with your machine’s serial plate.

Stop wasting time with translations and reprints. This is the original factory service manual for the SP-1100B. Access the Factory Manual and start your repair with the right data.
