Features & Advantages

• Hydraulic Roller Design: Engineered for heavy-load operation in diesel engines, providing superior oil-filled cushioning for reduced valve train noise and wear.
• Precision Rolled Surfaces: Heat-treated with 0.01mm tolerance for perfect rocker arm fit, extending camshaft life and improving fuel efficiency.
• OEM Balanced Construction: Machined to Mercedes-Benz specs for seamless integration, minimizing vibration in Actros/Axor truck applications.
• Versatile Application: Suitable for construction, mining, and bus operations, ensuring reliable performance in Euro 4/5 MP series.

Common Faults & Replacement Signals

• Valve Train Noise: Collapsed tappets cause ticking or clattering at idle—replace if hydraulic preload fails (oil pressure <2 bar).
• Poor Valve Clearance: Worn rollers lead to compression loss; check for misfires or power drops of 5-10%.
• Overheating or Seizure: Contaminated oil causes sticking; monitor for increased exhaust temps or metal in the oil filter.
• Rocker Arm Wear: High-mileage operation without timely replacement accelerates damage; inspect during 150,000 km service.

Installation Notes

1. Preparation: Drain oil and remove valve cover; measure tappet preload with feeler gauge (0.15-0.25 mm lash).
2. Alignment: Extract old tappet with magnet tool, insert new one ensuring roller orientation; torque rocker arms to 25 Nm.
3. Lubrication: Apply assembly oil to roller and stem; ensure hydraulic chamber fills during priming.
4. Testing: Reassemble, run engine at idle, and listen for noise; adjust valves after 500 km break-in.
5. Pro Tip: Use OEM-grade hydraulic oil and a calibrated torque wrench to avoid preload issues; replace in sets for even wear.
