One document settles what the pressures on these single drum rollers should actually read: the Bomag BW 145 D-3, BW 145 DH-3, BW 145 PDH-3 Service Training PDF, factory number 008 099 55, 117 pages covering all three machines. Hydraulic schematics trace the closed-loop travel circuit from travel pump to Poclain drum drive motor, and that travel chapter alone takes the biggest share of the book. Wiring diagrams at the back split the electrics into power supply, starter and monitoring, and brake circuits, so you can chase a dead vibration solenoid wire by wire. Set charge pressure to 25±1 bar, look for 220±5 bar at vibration start, and gap the Deutz valves at 0.3 mm intake, 0.5 mm exhaust. Every hour the roller sits, the lift behind it waits too. Bookmarks follow the factory chapter letters, so the pressure chart is two clicks from the cover; download it and put your gauge to work.
Complete the set for your BW 145 D-3, BW 145 DH-3, BW 145 PDH-3
