When Cylinder Block and Crankshaft Are Reused

  1. Measure the dimensions of the cylinder block main bearing housing inner diameter and crankshaft main journal diameter individually. Refer to [ENGINE UNIT: INSPECTION AFTER DISASSEMBLY ] and [ENGINE UNIT: INSPECTION AFTER DISASSEMBLY ].
  2. Apply the measured dimension to the "Main Bearing Selection Table".
  3. Read the symbol at the cross point of selected row and column in the "Main Bearing Selection Table".
    CAUTION: There are two main bearing selection tables. One is for odd-numbered journals (No. 1, 3 and 5) and the other is for even-numbered journals (No. 2 and 4). Make certain to use the appropriate table. This is due to differences in the specified clearances.
  4. Apply the symbol obtained to the "Main Bearing Grade Table" to select main bearing.
    NOTE: Service part is available as a set of both upper and lower.
