V50 L5-2.4L VIN 39 B5244S7 (2005)
There is an arrow marking on the top of the piston. This shall be turned to face forward in the engine block.
The connecting rods are symmetrical and can be turned arbitrarily. However, marked connecting rods shall be turned to face the same way.
Assemble connecting rod and piston with the piston pin.
Check that the classification of each cylinder/piston diameter as well as any numbering of the connecting rod correspond.
Install the piston pin's two lock rings. Check that the lock rings are positioned correctly in the piston. The opening shall be positioned vertically.
Caution! The lock ring can easily come off. Wear protective goggles.
Wipe clean at the bearing position in the connecting rod and the cap.
Install the bearing shells and center them in the bearing position.
Caution! If reusing previously used bearing shells, they must be installed in the same position as before.
Also pay attention when installing with regards to the crankshaft's rotational direction.
Installing pistons in cylinder bores
Use a piston ring compressor.
Lube the cylinder bores, pistons and bearing shells with oil.
Turn the crankshaft so that the crank pin is in lower dead center for the cylinder that the piston is to be installed in.
Make sure that the engine is suspended in such a way that the cylinder bores are as vertical as possible.
Note! The arrow on top of the piston must point forwards. Ensure that the classifications correspond!
Carefully press/tap down the piston (e.g., with the handle of a hammer).
When the piston has released the piston ring compressor, then turn the engine 180° in the stand. Install: 999 5746 Holder See: Tools and Equipment/999
5746 Holder in the connecting rod. Tighten the connecting rod until it is fixated against the big-end bearing journal.
