Piston ring to groove clearance

Use a feeler gauge to measure the axial clearance (H) of piston rings. If the
piston ring is marked on one side, that side must be facing up.
PISTON

Piston pin to small end clearance (A):

0,019 ÷ 0,01 mm (0,00075 ÷ 0,00040 in.)
Big end side clearance (B):
0,018 ÷ 0,030 mm (0,00071 ÷ 0,0012 in.).

Big end axial clearance

Measure axial clearance "A" between crankshaft (1) and connecting rod (2)
using a feeler gauge. Compare measured clearance with the table below.
