Let’s take a look at the approximate operating temperatures of each component of a vibratory roller.

Vibratory roller It is suitable for urban road construction and maintenance, as well as for trench excavation, building construction, pipeline backfilling, compaction in sports field construction, and lawn maintenance.
In operation, each component of a vibratory roller has its own specified normal temperature range. For example, the coolant typically operates at 80–90°C, while the hydraulic oil in the hydraulic transmission system should be maintained between 30 and 60°C. Temperatures outside this range can accelerate component wear and lead to changes in material properties.
During operation, vibratory rollers should also avoid overloading in low-temperature conditions and ensure proper functioning during the low-speed preheating phase. Only after the equipment has reached the specified ambient temperature should it be put into travel and work.
During operation, equipment inevitably encounters common malfunctions. When abnormalities arise, we should promptly shut down the machine and perform a thorough inspection; otherwise, the machinery may be forced to operate under excessive load. Such overloading can severely damage components. Therefore, it is essential to carefully monitor the condition of the roller’s cooling system.
What’s the issue with the vibratory roller’s operational difficulties?
I. Air Filters and Valves
1. Due to the harsh operating conditions of certain vibratory rollers, accumulated contaminants in the air filter can become clogged, preventing sufficient airflow into the combustion chamber. This results in inadequate oxygen supply during fuel combustion, causing the engine to fail to start. The solution is to replace the air filter.
2. Valve adjustment in diesel engines is a critical task; if the clearance is too small, it can lead to gas leakage, reduced power output, compromised cylinder sealing, ring scorching and carbon buildup, and even piston‑rod knock. Conversely, excessive clearance can result in incomplete exhaust expulsion, leaving the exhaust system clogged and further diminishing power, while also increasing the likelihood of component impacts within the crankshaft‑connecting‑rod mechanism, accelerating wear and tear. Over time, this can cause irreversible damage to the engine of a 3‑ton vibratory roller. If such issues arise, your machine will likely already be in the shop—so valve adjustments should always be performed by qualified technicians.
II. Grease Degradation and Substandard Fuels
1. When the engine oil in a vibratory roller has been used for too long, it degrades and its viscosity increases significantly. This is especially true in winter, when thickened oil residues can cause the engine to require multiple restarts. In such cases, check whether the lubricant level is low; if it is, replace the old oil with fresh, high‑quality grease.
2. Under relatively low-temperature conditions, substandard diesel engines produce excessive residual deposits that fail to meet specified purity standards, leading to solid paraffin buildup in the fuel lines and causing blockages in the fuel delivery system.
III. Battery Failure
In winter, the battery-powered vibratory roller experiences a decline in stored charge as ambient temperatures drop, leading to insufficient power and unstable idling. In such cases, the battery must be replaced or undergo battery restoration.
