Servicing the VM651(TOW TYPE ROLLER) beyond the schedule
Predictive Maintenance & Fluid Analysis
Monitor hydraulic oil condition at 1000-hour intervals by sampling for particle count and viscosity. Check exciter shaft seals for leakage, inspect drum bearings for noise or play, test vibration motor pressure, analyze engine oil for fuel dilution, check coolant pH levels, inspect fuel filters for water, monitor hydraulic tank strainer for debris, track exciter frequency stability, verify pump output pressure, and check hose integrity for bulges.
Corrective & Common Repairs
Replace hydraulic return filter if clogged, clean hydraulic tank interior, inspect exciter shaft bearings, replace worn drum scraper blades, check vibration isolation mounts, inspect tow hitch for deformation, test electrical connections, replace worn drive belts, check drum bearing pivot points, inspect chassis frame for cracks, verify hydraulic hose fittings, and replace faulty vibration switch.
Overhaul & Rebuild Points
Rebuild exciter shaft seals at 2000 hours, inspect drum bearings for wear, check hydraulic pump wear, replace vibration motor seals, inspect drum surface for damage, check chassis welds for cracks, replace worn pivot pins, inspect hydraulic tank for corrosion, check exciter shaft alignment, replace worn drum scraper holders, and inspect hydraulic hose clamps.
Seasonal & Environment Servicing
Use low-temperature hydraulic oil in cold weather, check coolant freeze point, inspect battery for cold cranking, grease pivot points more frequently in dust, clean air filter more often in dusty conditions, check drum scraper for ice buildup, inspect hydraulic hoses for cold cracking, verify vibration switch operation in cold, check tow hitch for ice, inspect drum for frost, and check electrical connections for moisture.

VM651(TOW TYPE ROLLER) fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| P0087 | Fuel rail/system pressure too low | Clogged primary fuel filter, failing lift pump, or air leaks on the suction side. | Replace primary fuel filter; verify lift pump primes at key-on; inspect suction-side hoses for air leaks. |
| P0191 | Fuel rail pressure sensor performance | Erratic rail pressure readings due to sensor failure or wiring issues. | Check filter age; test sensor 5V reference and ground; wiggle-test connector for intermittent faults. |
| P2201 | NOx sensor out of range | Faulty NOx sensor, damaged harness, or exhaust leaks upstream of the sensor. | Inspect NOx sensor connector and harness for damage; check for exhaust leaks upstream of the sensor. |
| P20EE | SCR NOx efficiency low | Poor SCR conversion, often due to sensor issues, DEF injector crystals, or contaminated DEF. | Verify DEF quality (32.5% urea); inspect DEF injector for crystals; verify NOx sensor operation. |
| P1C54 | SCR inducement derate | Power reduction triggered by an unresolved emissions/SCR fault. | Resolve the root SCR/DEF code first; top off clean DEF; complete parked regeneration if required. |
| U029D | Lost NOx sensor communication | ECU cannot communicate with NOx sensor A due to electrical faults. | Check battery voltage; inspect NOx connector pins for corrosion; verify power, ground, and CAN continuity. |
| U0073 | CAN bus off | Module network drop, often caused by low battery voltage or poor grounds. | Load-test battery; clean and tighten ground connections; inspect harness at articulation points. |
| T135 | Transmission oil temperature high | Overheating transmission fluid due to low level or blocked cooler. | Check transmission oil level; inspect cooler fins for debris; allow machine to cool before heavy work. |
| T072 | Output speed sensor no signal | Missing speed signal causing erratic shifting or limp gear. | Inspect speed sensor connector; check wiring integrity at articulation points. |
| ENG OIL | Engine oil pressure low | Oil pressure below safe threshold due to low level, leaks, or sensor failure. | Check oil level immediately; inspect for leaks and filter condition; test sensor before condemning the pump. |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
VM651(TOW TYPE ROLLER) attachments & work tools
Drum Configuration
The VM651 utilizes a single smooth drum with a width of 2.1 m (82.7 in) and a diameter of 1.5 m (59.1 in). The VM651PD variant shares these dimensions but includes a water-filled drum system for increased static line load and compaction force.
Towing & Hitch System
The machine is designed as a tow-type roller with a hitch system compatible with standard towing vehicles. It features lifting and towing eyes for transport and includes a hydraulic drive system for the exciter shaft that connects to the towing vehicle's hydraulic circuit.
Vibration Control
The exciter shaft operates at a frequency of 40 Hz and is hydraulically driven. Vibration can be switched on and off remotely from the towing vehicle, allowing for controlled compaction intervals on larger sites.
Engine & Power
The VM651 is powered by a 3240 cm³ Deutz diesel engine, specifically the F3L914 model, producing 42-57 hp (28-42 kW). The engine provides the necessary power for the hydraulic systems and exciter drive.
Compaction Depth
The machine is designed for compaction depths ranging from 80 cm to 100 cm (31.5-39.4 in), depending on soil type and moisture conditions. This depth capability supports its use in larger compaction sites.
Safety & Operator Protection
Standard equipment includes a Roll Over Protection Structure (ROPS) and a seat belt. An optional ROPS cab is available for enhanced operator protection and comfort in varying weather conditions.
Electrical & Starting System
The VM651 features an electrical starting system, a 12-volt battery, starter, and alternator setup. Optional lighting and a standard back-up alarm are included to enhance visibility and safety during operation.
Weight & Dimensions
The operating weight ranges from 6300 kg to 6500 kg (13,889-14,330 lb). Transport dimensions are 4.6 m (15.1 ft) in length, 2.3 m (7.5 ft) in width, and 1.73 m (5.7 ft) in height.
