When a BW 75 S-2 stops pulling mid pass, the driveline linkages are the first place to look: a stretched control cable, a slipping travel clutch, or a worn centrifugal clutch. Meanwhile the lift sits half compacted and the crew waits. This 24 page PDF is the BOMAG repair manual for the BW 75 S-2 double vibratory roller, serial numbers 101 020 01 1001 and up, publication number 008 912 49.
It covers the mechanical adjustments that keep this roller working: replacing and adjusting the throttle cable and control cable, checking and setting the travel clutch, replacing the brake cable, adjusting the parking brake, and pulling the centrifugal clutch off its taper. Tightening torques and the factory engine speed settings are included, so you set everything back to spec.
Thirteen bookmarked sections in 24 pages mean you open the file, jump straight to the one procedure you need, and get the machine back in the pass.
