Wacker's DPU 4045H, DPU 5045H repair manual PDF, 158 pages filed under OEM number 0215959, strips either vibratory plate down to a bare exciter housing and walks it back together in factory sequence. Disassembly and assembly fill most of the book, moving from the covers and centrifugal clutch through the Bowden cable, diesel engine, guide handle head, and exciter shafts, with each rebuild closing on bearing fits and thread-locker call-outs. A malfunction chapter ties weak advance or reverse travel back to the hydraulic control, and metric plus SAE torque tables finish the book in Nm and ft-lb. Measure your exciter V-belt first; at 15.5 mm wide it is done, and when the eccentric weights go back on, torque the cheese head screw to 295 Nm with a 14 mm Allen. Guess at either number and you pay for the teardown twice. Bookmarked and text-indexed, this PDF goes wherever the plate is working.
