Need the factory specs for your vibrating tandem roller? This 319-page JCB VMT260 Service Manual PDF (OEM #9803/9530-6) covers the VMT160, VMT260, VMT 160-90, VMT 260-100, and VMT 260-120 rollers with Kubota D722 engine variants. Inside, you get full hydraulic schematics detailing the exact routing for the propulsion, steering, and vibration circuits. Open up the electrical section to find complete wiring diagrams alongside step-by-step troubleshooting charts covering everything from the Kubota engine to the automatic vibration system. Lock down the ROPS structure mounting bolts to 210 Nm and secure the M16 drive motor bolts to 195-215 Nm before sending the roller back to the job site. Your crew is waiting on this machine. Grab the right numbers instead of relying on internet guesses. This file is fully bookmarked so you can pull it up on your tablet, jump straight to the correct spec, and get to work.
