Note: The bearings for replacement in the table are for later 3116 engines. The bearings for replacement on 3114 and 3126 engines will be found in the appropriate Parts Manual.

Note: Some 3116 cylinder blocks do not have oil grooves in the bearing saddle. The part number of the cylinder blocks that do not have oil grooves in the bearing saddle are 149-5403 Block Gp .

Note: The part number for the cylinder block is located on the right side of the cylinder block. The exhaust manifold is mounted on the right side of the cylinder block.

Note: Incorrect bearings cannot be accidentally interchanged between earlier 3116 cylinder blocks and later 3116 cylinder blocks. The bearing tabs and the tab slots on the cylinder block will not be in alignment if the incorrect bearings are used.

Note: Additional information on reconditioning procedures can be ordered. Refer to the following documents:
