Bomag wrote this repair manual, publication 0852636, for the BW124D smooth drum, the BW124PD padfoot and the BW124PDB with the leveling blade, serial number prefix A219, and the PDF runs 262 pages. The book is built system by system. Transmission is the biggest chapter at pages 127 to 178, with travel pump repairs and the procedure for flushing the circuit after a failure, then steering on 183 to 204, vibration on 205 to 226 and the leveling blade on 237 to 254. The Deutz F3L1011 gets its own removal and installation chapter, and specifications start on page 13. Nominal values are printed where you need them: 180 bar starting and 60 bar operating pressure on the vibration pump, 200 bar at the vibration valve on page 222, steering relief at 1,850 psi. Guess those and you condemn a pump that was fine. Forty four bookmarks and a live text layer put the right page one tap away.
