From the Deutz 2012C diesel with EMR through the hydrostatic travel drive, vibration circuit, steering and electrics, this 255-page Bomag BW 216, BW 219 and BW 226 Service Training PDF (OEM 008 097 20) walks the DH-4 and PDH-4 versions of all three single drum rollers end to end. Wiring diagrams and hydraulic schematics close out the book, behind an electrics section filling roughly the last third with fault code and signal descriptions. Travel pump, drum drive motor and exciter each get their own test and adjustment points, so you chase a weak drive or dead vibration against measured pressures instead of hunches. Set charge pressure at port X near 26 bar on your 216, and pull the plug-type injection pump screws down in stages from 5 Nm to 30 Nm. A roller sitting between passes for want of one valve setting bleeds a whole shift. Bookmarked and text-searchable, the download hands you that figure in seconds.
