Dimensional Checks

Dimensional check of pistons The actual measured values must conform to those indicated in the drawing. Piston nominal diameter: 92.00mm

45.00

28.00

Hole offset 0.8mm

6.00

Diameter of gudgeon pin housing on piston: Ø 20 +0.011/ +0.005 Ext. diameter gudgeon pin: Ø 20 0/ -0.005

The pistons are offset, which means that pistons intended for the right-hand bank are different from those for the left-hand bank. CAUTION! In addition to dimensional checks, always perform a careful visual inspection: The components must be free from dents, grazes, chips and other visible defects. Scoring and marks on the piston skirt resulting from careless handling may result in increased blow-by.
