Installation Notes
Pre-Installation Checklist:
1.Component Inspection: Verify part number (082V04120-0024) and check for cracks or deformation
2.Cleanliness: Ensure valve bridge seats and contact surfaces are free of carbon deposits and debris
3.Measurement: Check valve stem heights for consistency (max 0.05 mm variation between paired valves)
4.Lubrication: Apply clean engine oil to all moving contact surfaces before installation
Installation Steps:
1.Positioning: Place valve bridge on exhaust valve stems with flat surface facing rocker arm
2.Alignment: Ensure bridge sits evenly on both valve stems without rocking or binding
3.Rocker Arm Installation: Install rocker arm and adjust to proper valve lash specification
4.Torque Specifications: Tighten rocker arm shaft bolts to 85 ± 5 Nm in specified sequence
5.Clearance Check: Verify valve lash (0.25-0.30 mm cold) using feeler gauges
Critical Warnings:
Never reuse old valve bridges when replacing valves or performing engine work
Always replace valve bridges in pairs per cylinder to maintain balanced operation
Check rocker arm and valve stem tips for wear before installation
Verify proper valve bridge orientation to prevent binding or premature wear
Post-Installation:
Prime oil system before initial startup
Run engine at idle and check for unusual valve train noises
Re-torque rocker arm bolts after first 500 km of operation
Monitor valve clearances during initial break-in period
