Installation Notes
Pre-Installation Checklist:
1.Inspect Components: Verify part number (081V04302-0062) and check for straightness or damage (roll on flat surface to detect bends).
2.Clean Surfaces: Ensure lifter bores and rocker arm contacts are free of debris and oil residue.
3.Lubrication: Apply clean engine oil to both ends of the push rod before installation.
Installation Steps:
1.Position Push Rod: Insert the push rod into the lifter bore, ensuring it sits squarely on the lifter cup.
2.Align with Rocker Arm: Gently guide the upper end into the rocker arm socket.
3.Valve Lash Adjustment: Set valve clearance to 0.25–0.30 mm (cold engine) using a feeler gauge.
4.Torque Specifications: Tighten rocker arm shaft bolts to 85 ± 5 Nm in the manufacturer’s specified sequence.
Critical Warnings:
Never reuse old push rods; replace in sets per cylinder to ensure uniform performance.
Check lifter and rocker arm wear before installation to prevent premature failure.
Avoid over-tightening; use a calibrated torque wrench for accuracy.
Post-Installation:
Prime the oil system before startup to ensure proper lubrication.
Run the engine at idle and monitor for unusual valve train noises.
Re-check valve clearance after the first 500 km of operation
