Troubleshooting
Main bearing oil channel depth and width
misalined or insufficient oil pressure result
in poor lubrication of the cylinder wall
Repair or adjust the oil pressure to
specification
Excessively big clearance between the

Poor lubrication for cylinder wall and piston
Dredge the oil line to improve the
lubricant splashing problem
Piston pin and connecting rod end are
installed too tightly
Adjust piston pin tension to normal level
Connecting rod bearing is assembled too

Adjust the bearing tension to normal level
Piston skirt ovality is too big
Replace the piston with normal ovality
