– Compare A, B, C and D to determine whether the liner is conical or oval. – Compare the inner diameter of the liner with the external diameter of the piston skirt. Change the piston and liner if the values exceed those specified. Values indicated: Liner inner diameter..........................106,48 - 106,52 mm Maximum out-of-roundness at top of liner .......... 0,05 mm Maximum taper at top of liner ............................. 0,05 mm Piston - Cylinder liner clearance ...............0,08 - 0,15 mm
