At a Glance
The BMW R51 R61 R66 R71 Service Repair Manual German 1939 is a workshop reference for owners, restorers, and mechanics working on these classic BMW motorcycles. Written in German, a factory manual from this period typically covers routine servicing, mechanical adjustments, and repair procedures using technical descriptions and illustrations. It can help readers understand the original service approach before tackling maintenance or investigating wear on a motorcycle built in 1939.
Typical coverage includes engine lubrication, valve adjustment, fuel delivery, ignition, clutch operation, transmission servicing, and final drive maintenance. Guidance on brakes, wheels, steering, and electrical equipment may also help with fault diagnosis and restoration planning. Where provided, torque specifications, clearances, component diagrams, and part references help identify correct assembly practices and suitable replacement items. Because specifications and arrangements can vary between models, check each procedure against the motorcycle's exact designation and existing components. German technical vocabulary should also be interpreted carefully before applying settings or repair instructions. The PDF is available for download.
