This is the Wacker RD11 repair manual, covering the RD11A, RD11V, and RD11AEC vibratory rollers built under item numbers 7693, 7694, and 7695. Depending on the machine it carries a Vanguard or Honda GX610 engine. Across 112 pages the manual is organized by system for practical shop repair.
You get technical data and hydraulic pressures, operation and maintenance schedules, and detailed coverage of the hydraulic system with the series and parallel drive schematics, manifold blocks, and relief valves. The roller chapter documents the front and rear drum assemblies, the exciter, and the drive motors.
Electrical schematics, a troubleshooting chapter for the drive, vibration, steering, and starting systems, a threadlocker and sealant guide, and full metric and inch torque tables round it out. Whether you are chasing a vibration fault or rebuilding a drum, this is the reference for servicing an RD11 roller.
