Part of the John Deere Repair Manuals.
Working on a John Deere 646B? This 55-page JD646-B Technical Manual PDF (OEM TM-1116) walks you through predelivery, delivery, and after-sale service on the compactor, from fuel system bleeding to lubrication points. Inside: factory safety procedures, full machine specifications (engine power, hydraulic system, dimensions, capacities), and a maintenance section covering storage prep, pre-cleaner service, and gauge operation. You also get torque tables straight from Deere engineering. Set the wheel retaining cap screws to 450 lb-ft, tighten the transmission and steering oil filter covers to 55 lb-ft, and run tire pressure at 70 psi. Change engine oil every 200 hours, not when the forum says so. Your compactor doesn't care about guesses; it cares about numbers. Bookmarked PDF opens on any device, so bring the tablet to the machine and get wrenching.
