Fig. 2.169. Measurement of a side gap of the lower head of a rod

Measure a side gap of the lower head of a rod (fig. 2.169).

If the side gap of the lower head of a rod exceeds a maximum, replace the piston, a piston finger, a piston ring and a rod assembled.

Normal gap: 0,14–0,36 mm.

Maximum gap: 0,435 mm.
