A tandem roller that creeps in neutral or loses vibration mid-mat leaves a whole paving train standing, and the Bomag BW 180 AD repair manual PDF (OEM 008 912 53) is the factory answer: 326 pages on the tandem vibratory roller, from pressure tests to full drum teardown. Flushing schematics map the front and rear drum drives and the vibration circuit, while the troubleshooting diagram traces each symptom back to the failed component. Supplier documentation fills the back half of the book, rebuilding the A4VG and A10VG travel pumps, MS/MSE drum drive motors and the A2FM 32 vibration motor down to the rotary group. Check the steering circuit against its 200 ±10 bar nominal, and confirm the brake releases at 26 bar before you condemn the drive. Every hour this machine sits, the lift waits. Bookmarked and text-searchable, the PDF puts each of those sections one tap away.
