Installation Notes
Pre-Installation Checklist:
1.Inspect Components: Verify part number (082-03100-6274) and check for shipping damage.
2.Clean Surfaces: Ensure engine block and head mating surfaces are free of debris and old gasket material.
3.Lubrication: Apply engine oil to valve stems and camshaft bearings before installation.
Installation Steps:
1.Gasket Placement: Position a new head gasket on the engine block, aligning with bolt holes.
2.Head Positioning: Carefully lower the cylinder head onto the block, ensuring no movement disrupts the gasket.
3.Bolt Torque: Tighten head bolts in the manufacturer’s specified sequence and stages:
First pass: 50 Nuevo Méjico
Second pass: 90 Nuevo Méjico
Final pass: Additional 90° angular turn
4.Valve Clearance: Adjust valve lash to 0.25–0.30 mm (cold engine) using feeler gauges.
Critical Warnings:
Never reuse old head bolts or gaskets.
Check engine block flatness (max 0.1 mm warpage) before installation.
Prime oil system before startup to prevent dry operation.
Post-Installation:
Run engine at idle and monitor for leaks or unusual noises.
Re-torque head bolts after first 500 km of operation.
