The BY1000495068 EVB Valve Bridge Assembly is a key element in the valve train of modern SHACMAN diesel engines. It sits directly on top of the valve stems, typically bridging two exhaust valves.
Its primary function is to transfer the actuating force from a single rocker arm or cam follower evenly to two valves simultaneously. This ensures both valves open and close in perfect unison.
This synchronized operation is critical for efficient cylinder breathing. It allows for optimal exhaust gas scavenging, which directly impacts engine power output and fuel economy.
In advanced emission-controlled engines, precise valve timing enabled by the BY1000495068 is essential for the proper function of systems like Exhaust Gas Recirculation (EGR).
A worn or faulty valve bridge can lead to uneven valve lift, causing poor compression, power loss, increased fuel consumption, and elevated nitrogen oxide (NOx) emissions.
Therefore, maintaining the integrity of the BY1000495068 assembly is not just about engine performance but also about environmental compliance and operational cost control.
1. Ensure the engine is cool and the cylinder head is properly secured. Clean the valve bridge pocket and all contact surfaces thoroughly.
2. Lubricate the contact pads and the pivot point of the new BY1000495068 assembly with clean engine oil or assembly lubricant.
3. Carefully place the bridge onto the valve stems, ensuring it sits squarely and engages correctly with the valve stem tips.
4. Install the rocker arm or cam follower assembly above the bridge. Manually rotate the engine to ensure no binding occurs.
5. Perform valve lash adjustment according to the manufacturer’s specified procedure and clearance values for your engine model.
6. Tighten all related fasteners to the specified torque sequence and values. Double-check the valve clearance after torquing.
7. Reassemble remaining components, start the engine, and listen for abnormal valve train noise, indicating proper installation.
• Inspect the BY1000495068 assembly during every major engine overhaul or cylinder head service.
• Check for visible signs of wear, pitting, or cracking on the contact pads and pivot areas.
• Measure the bridge for straightness and check for any galling or scuffing marks that indicate insufficient lubrication.
• Always replace the valve bridge in its designated position; avoid mixing bridges between cylinders.
• Ensure the engine’s lubrication system is clean and functioning properly to extend the life of the BY1000495068.
• Keep a detailed service record, noting the replacement of valve train components like the BY1000495068 assembly.
