8. While pressing in the piston pin, check the press-in pressure. If lower than the index,
replace the piston pin or connecting rod.
Pressure: 4.90～14.70kN(500～1500kgf, 1100～3300lbf)
9. Check the pressed depth of piston pin. If it is out of the standard value, restart from
the 1
st
step.
Press-in depth of piston pin: 1.65～2.05mm{0.0650～0.0807in}
