Cylinder Block Assembly: Testing and Inspection

1. Measure wear and taper in directions X and Y at three levels in each cylinder as shown.





- Cylinder Bore Size:
- Standard (New):
- A or 1: 85.010 - 85.020 mm (3.3468 - 3.3472 inch)
- B or 11: 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 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)
