Use Tooling (A) to turn the flywheel in order to access the connecting rod cap that will be removed.
Illustration 2 g01431477Note: Inspect and carefully handle the fractured connecting rod and the connecting rod cap for the proper identification mark. The connecting rod and the connecting rod cap should have an etched number on the side. Clean with Tooling (D) if the etching is hard to view. The number should match the cylinder number. Mark the connecting rod and the connecting rod cap, if necessary. Improper handling of the fractured connecting rods and the connecting rod caps can cause misalignment during assembly. The connecting rod caps should be placed on the side in order to prevent damage.
Remove bolts (3) and the spacer. Remove connecting rod caps (4).

Use the adjusting nut to raise the piston until the connecting rod is above the crankshaft journal. Remove Tooling (B) that is not against the crankshaft journal. Remove the upper half of the connecting rod bearing.
Push the connecting rod into position and remove the rest of Tooling (B). The connecting rod should swing over the crankshaft journal. Check in order to avoid contact between the connecting rod and the connecting rod journal. Installation Procedure
Clean the connecting rod cap and the connecting rod bearing bore with Tooling (D) and clean lint free rag. Inspect both the connecting rod cap and the connecting rod bearing bore. Check for carbon on the connecting rod cap and the connecting rod bearing bore.
Inspect the fractured joints and remove any loose material. Clean the face with a clean paint brush to remove loose material on the fractured areas.
Check the clearance of the bearings. Refer to Disassembly and Assembly, "Bearing Clearance - Check" for the correct procedure.
Use Tooling (D) and a lint free rag to clean the new bearing. Apply a light film of clean oil to back of bearing surface and a generous amount of oil on the front of each bearing
Install the upper half of the connecting rod bearing in the connecting rod. Inspect in order to ensure that the tab on the back of the bearing is in the bearing tab groove on the connecting rod.
Inspect the connecting rod bearing and the crankshaft journal for seating, alignment, and cleanliness. Apply clean engine oil.
Push the connecting rod into position over the connecting rod journal and install Tooling (B).
Position the connecting rod over the crankshaft. Use Tooling (C) to lower the piston on the crankshaft journal.
