Cylinder Block Assembly: Testing and Inspection

Piston, Rings and Cylinder Bore, Checking

Piston Ring Gap, Checking





Special tools, testers and auxiliary items required

• Feeler gauge

- Insert the ring into the bottom of the cylinder opening at a right angle from above, approximately 15 millimeter (mm) from cylinder edge.





Piston Ring Groove Clearance, Checking





Special tools, testers and auxiliary items required

• Feeler gauge

- Before measuring, clean the ring groove.





Pistons, Checking





Special tools, testers and auxiliary items required

• External micrometer 75 to 100 mm

- Take the measurement approximately 10 millimeter (mm) from the lower edge of the piston skirt and offset 90° to the piston axis.

Deviations from nominal dimension: Max. 0.04 mm

Cylinder Bore, Checking





Special tools, testers and auxiliary items required

• Internal dial gauge 50 to 100 mm

- Measure diagonally at 3 positions transversely - A - and longitudinally - B -.

Deviation from nominal size: Max. 0.08 mm.

• Cylinder bore must not be measured if the cylinder block is secured to the engine stand with the engine lateral bracket (T03001), or else the results may be incorrect.
