1. Preparation
Note: On some engine types, the supply unit is in a different position. It can be
necessary to remove some platform components to get access to the top
end bearing cover.
Note: This procedure is for engines where the supply unit is near the middle of
the fuel side on engines with 9 to 12 cylinders. For engines with 6 to 8
cylinders, the procedure can look different because the supply unit is in a
different position on the engine.
1) Read the data in 0012−1 General Guidelines for Lifting Tools.
2) If necessary, remove the applicable platform components to get access to the top
end bearing cover.
3) Prepare the piston, refer to 3303−3, paragraph 1.
4) Install the platform (94143, Fig. 1).
5) Make sure that the turning gear is locked to prevent movement of the crankshaft.
