Install short pieces of rubber hose over both connecting rod bolts in order to protect the crankshaft from the threaded portion of the connecting rod bolts. |
- Lubricate the bearing for the upper connecting rod journal with clean engine oil.
- Align the piston rings on the piston so that the distance between the gaps is 120 degrees.
- Install Tooling (A) on the piston.
Note: Ensure that Tooling (A) is installed correctly and that the piston can easily slide out of the tool.
Note: The arrow or the "FRONT" mark that is on the top of the piston must be toward the front of the engine.
