A new piston skirt with only one notch is now used. The asymmetrically designed piston skirt must be assembled correctly in order to avoid engine damage. Note: If the piston skirt is not assembled correctly, the piston cooling jet will be damaged and a piston seizure will occur.Refer to the appropriate Disassembly and Assembly Manual in order to remove and install the piston skirts. Refer to the appropriate Specifications Manual in order to find the proper torque specifications.Required Parts
Table 1 contains the parts needed for this change.Note: All six piston skirts must be changed at the same time. Do not use the double notch and single notch piston skirt together.
