Cylinder Block Assembly: Testing and Inspection
1. Measure wear and taper in directions X and Y at three levels in each cylinder as shown.
- Bore Taper
- Limit: (Difference between first and third measurement) 0.05 mm (0.002 inch)
- If measurements in any cylinder are beyond Oversize Bore Service Limit, replace the block.
- If block is to be rebored, refer to Piston, Testing and Inspecting after reboring.
NOTE: Scored or scratched cylinder bores must be honed.
- Reboring Limit: 0.50 mm (0.020 inch)
2. Check the top of the block for warpage. Measure along the edges and across the center as shown.
- Engine Block Warpage:
- Standard (New): 0.07 mm (0.003 inch) max.
