Piston, Connecting Rod, and Bearing Installation





1. Install the connecting rod bearing clips in the connecting rod and connecting rod bearing cover.
2. Apply engine oil to the connecting rod bearing clips.
3. Set the piston ring joint, piston 2.

* First piston ring, right-hand ring, in position (1)
* Second piston ring, minute ring, in position (4)
* Interim ring of oil scraper ring in position (5), steel band rings of oil scraper ring in position (2 and/or 3)





4. Install piston 2.

* Apply engine oil to the piston and cylinder bore.

Important: The arrow (1) on the piston head points to the engine timing side. The bead (2) on the connecting rod points to the transmission side of the engine.


* Force the piston rings together with the piston ring tensioning belt.
* Push in the piston.





5. Set the piston ring joint, piston 3.

* First piston ring, right-hand ring, in position (1)
* Second piston ring, minute ring, in position (4)
* Interim ring of oil scraper ring in position (5), steel band rings of oil scraper ring in position (2 and/or 3)





6. Install piston 3.

* Apply engine oil to the piston and cylinder bore.

Important: The arrow (1) on the piston head points to the engine timing side. The bead (2) on the connecting rod points to the transmission side of the engine.


* Force the piston rings together with the piston ring tensioning belt.
* Push in the piston.





7. Install connecting rod bearing covers 2 and 3 (1).
8. Apply engine oil to the connecting rod bearing journal.

Notice: Refer to Fastener Notice (Fastener Notice) .

9. Install the bolts.
