Cylinder Block Assembly: Testing and Inspection

INSPECTION
1. Measure wear and taper in direction X and Y at three levels in each cylinder as shown.
^ Cylinder Bore Size:
- Standard (New):
^ A or I: 85.010-85.020 mm (3.3468-3.3472 inch)
^ B or II: 85.000-85.010 mm (3.3465-3.3468 inch)
- Service Limit: 85.070 mm (3.3492 inch)
- Oversize:
^ 0.25: 85.250-85.260 mm (3.3563-3.3567 inch)
^ 0.50: 85.500-85.510 mm (3.3661-3.3665 inch)
^ 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 the block is to be rebored, refer to piston clearance inspection after reboring.
NOTE: Scored or scratched cylinder bores must be honed.
Reboring Limit: 0.50 mm (0.020 inch) max.





2. Check the top of the block for warpage. Measure along the edges and across the center as shown.





^ Engine Block Warpage:
- Standard (New): below 0.07 mm (0.003 inch) max.
- Service Limit: 0.10 mm (0.004 inch)
