Built for the Bomag BW 27 RH-4i rubber tire roller, this 706-page Service Manual PDF (OEM ID 008 922 89) provides the factory repair data required to keep your compaction equipment moving on the mat. Detailed hydraulic schematics map out the closed-loop travel pumps and A6VM travel motors, and dedicated troubleshooting sections isolate faults fast. The documentation also unpacks complete EMR4 fault code lists, pneumatic diagrams for the tire inflation system, and full electrical wiring schematics. The text lays out exact factory measurements, such as the 6 bar fuel pump operating pressure and the 0.17 to 1.45 mm gap clearance for the crankshaft speed sensor. When the paving train is waiting and the machine stalls mid-pass for want of a single sensor value, this bookmarked, text-searchable file gets you to the correct specification the first time.
