Q: How to service and repair the piston on Ford F-350 Super Duty?
A: A proper service and repair process for the piston should start through complete subassembly disassembly. Begin by stripping off the clips followed by extracting the piston pin through a combination of piston and connecting rod units so you can detach the connecting rod from the piston. Examine and clean both the piston units together with the connecting rod components. At assembly time position the connecting rod into the piston while its identification markings ought to be in front orientation. Place the connecting rod into the piston opening before applying motor oil to the piston pin bore and pin for lubrication. The piston pin installation process begins by placing it inside the piston and connecting rod and ends with the retaining clip positioning.
