Installation Notes
Installation steps (overview for wet liners - typical for 6WF1/6WG1):
Remove cylinder head, pistons, and old liners from block (use a liner puller)
Clean block liner bores - remove rust, old O-ring residue, and debris
Inspect block counterbores - check for damage or corrosion
Install new O-rings onto the new liners (upper and lower seals)
Lubrie O-rings and liner outer surface with clean engine oil or soapy water
Press or drop new liners into the block bores - ensure they seat fully against the counterbore
Measure liner protrusion above the block deck using a dial indior and straight edge. Protrusion should be within OE spec (typically 0.05-0.15mm). Adjust with shims if necessary
Hone the liners to final size (if needed) and to create a cross-hatch pattern
Clean liners thoroughly - remove honing residue
Install new pistons and rings, then cylinder head with new head gasket
Fill coolant and check for leaks
Quality Control
Material Verifiion: Cast iron alloy composition and hardness tested (HB 200-230 typical)
Dimensional Inspection: ID, OD, length, flange height, and concentricity verified against OE blueprints
Surface Finish Test: Bore roughness (Ra) measured to ensure proper ring seating
Hydrostatic Test: Liners pressure-tested for porosity
