9 Improper Maintenance Practices for Road Rollers – Are You Making These Mistakes?

With the rapid development of machinery manufacturing, continuous advancements in industrial technology, and the ongoing urbanization, road rollers are increasingly utilized in various scenarios. However, 

equipment failures and issues are inevitable during operation, making scientific and standardized maintenance essential. Due to common misconceptions among technicians, improper maintenance practices 

can lead to performance degradation or premature equipment failure. Below are 9 improper maintenance practices for Hengwang Road Rollers – check if you’re making these mistakes!

1. Installing New Parts Without Matching Sizes

When replacing cylinder liners and pistons, always verify the size grouping codes of both components. Ensure the codes match to maintain the standard clearance.

2. Incorrect Cylinder Clearance Measurement

Measure the cylinder clearance along the major axis of the ellipse, i.e., perpendicular to the piston pin hole on the piston skirt.

3. Heating Pistons with Open Flame

Direct flame heating causes uneven thermal expansion, leading to deformation. High temperatures can damage the metal structure, reducing wear resistance and service life.

4. Sandpaper Polishing of Bearing Bushings

Polishing bushings with sandpaper embeds abrasive particles into the alloy layer, accelerating wear on both bushings and crankshafts.

5. Topping Up Oil Without Replacement

Used oil contains contaminants. Simply topping up fails to remove residues in the oil pan and lines, compromising lubrication efficiency.

6. Misuse of Grease

Applying grease on cylinder gaskets allows it to seep into coolant or oil passages. Residual grease under high pressure can damage gaskets and cause leaks. Prolonged heat exposure also leads to carbon buildup 

and premature aging.

7. Over-Tightening Bolts

Excessive torque may strip threads or break bolts, jeopardizing structural integrity.

8. Incorrect Tire Pressure

Over- or under-inflated tires reduce lifespan and pose safety risks during operation.

9. Adding Cold Water to an Overheated Radiator

Sudden cooling of an overheated radiator risks cracking the cylinder head or block due to thermal shock. Allow the engine to cool naturally.
