If you encounter issues with your BOMAG road roller, don’t worry. As a leading manufacturer of road roller parts, we’ve compiled a list of frequent repair cases and their corresponding solutions. For reliable road roller spare parts suppliers or wholesale road roller parts factories, always source genuine components, such as Dynapac road roller spare parts or OEM BOMAG parts, to ensure longevity.

Case 1: Pilot Pump Failure

If the pilot pump outlet pressure drops to 1.1MPa (normal: 3.14MPa), the pump is likely damaged. Check the pilot filter for aluminum debris. If found, replace the pump and adjust the safety valve. Pro Tip: Contaminated filters often stem from low-quality aftermarket parts – always use certified road roller parts factory components.

Case 2: Rear Pump Displacement Mechanism Failure

Symptoms: Slow left travel, swing, arm, and bucket movement. Pressure tests normal (30MPa). Cause: Foreign material jamming the stepped regulating piston in the rear pump displacement mechanism. Solution: Disassemble, clean, and reassemble. Prevention: Regularly inspect hydraulic components; partner with trusted road roller spare parts suppliers to avoid counterfeit parts.

Case 3: Travel Deviation

During testing, deviation shifts to the opposite side after swapping the main pump lines. Indicates main pump or displacement mechanism issues. Recommendation: Use diagnostic tools to pinpoint faulty main parts of a road roller; source replacements from wholesale road roller parts factories for cost efficiency.

Case 4: Rear Wheel Sudden Lock

Cause: Brake master cylinder piston cup sticking due to:

Solution: Flush the system, and use OEM-specified brake fluid. For replacements, choose road roller parts with manufacturer-approved seals. Genuine BOMAG parts prevent fitment failures.

Water/contaminants in brake fluid

Swelling from incompatible fluid

Poor fit between cup/master cylinder bore

Seal material defects or dimensional mismatches

Case 5: ASC Activation & Engine Stall on Incline

1. Low tire pressure: Triggers ASC via reduced traction.
2. Engine issues: Fuel delivery, ignition, or sensor faults causing power loss.
