The 6I3189 Spacer Plate is available for parts service. This spacer plate is 0.076 mm (.0030 in) thinner than the standard 2W8601 Spacer Plate. The 6I3189 Spacer Plate provides an alternative to counterboring all six cylinder liner seats in order to increase average liner projection to within the specification range. The cylinder liner projection specification range is 0.03 to 0.15 mm (.001 to .006 in).
NOTE: The 6I3189 Spacer Plate should NOT be installed to achieve liner projections greater than 0.15 mm (.006 in).
Measure cylinder liner projection. See the appropriate Service Manual Module. The 6I3189 Spacer Plate CAN NOT be used unless:
-
- * Inspection of cylinder block indicates no measurable erosion greater than 0.03 mm (.001 in) deep directly under cylinder liner flanges.
- * Cylinder liner projection does not vary by more than 0.05 mm (.002 in) between cylinders.
- * Cylinder liner projection does not vary by more than 0.05 mm (.002 in) between the measurements for any one cylinder.
- * Inspection of cylinder block indicates no measurable erosion greater than 0.03 mm (.001 in) deep directly under cylinder liner flanges.
This type of damage must be corrected by counterboring the cylinder liner seats and installing the appropriate stainless steel inserts prior to final assembly of the engine with the 6I3189 Spacer Plate.
