When a BW 75 H stops shaking mid-pass, the fix usually lives somewhere in these 122 pages: this Bomag BW 75 H service manual PDF (OEM ID 008 915 16) is the factory repair book for the double vibratory roller, from safety regulations through full drum and travel drive repairs. Hydraulic diagram 820 601 13 and wiring diagram 820 031 19 map every line and wire in the machine, and a dedicated troubleshooting chapter works the vibration drive fault by fault. Repair chapters take you through the travel cable, drum bearings, exciter shaft, travel pump, and drum drive, each closing with the correct adjustment. Set exciter shaft end float between 0.8 and 1.6 mm, and heat the drive gears to 200 degrees C before pressing them onto the drum axles. Every hour spent hunting a spec is an hour the roller sits. Bookmarks in this text-searchable PDF put the section you need two taps away.
