Disassembly And Assembly Of Subassemblies: Piston: Assembly

WARNING: This page is about a different car, the 2009 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Lubricate all parts with clean engine oil.

NOTE: Install the piston in the connecting rod with the cylinder number side of the rod and the indentation notch in the piston on the same side.

NOTE: The oil hole in the connecting rod must face the RH side of the cylinder block and the arrow on the piston must face the front of the engine block.

NOTE: If the piston pin is removed from the piston, a new piston and piston pin must be used. Do not reuse the piston or the piston pin.

Gradually heat the pin bore side of the connecting rod to approximately 232°C-316°C (467°F-626°F) and immediately install the piston pin.
Using the Piston Pin Service Set, press the piston pin into the piston and connecting rod assembly.
