What This Piston is Used For
The piston transfers combustion force through the connecting rod to the crankshaft while the piston rings seal combustion pressure and control oil on the cylinder wall.
During a rebuild, the cylinders should be accurately measured for diameter, taper and out-of-round condition before selecting standard or oversize pistons.
Parts to Inspect During Piston Replacement
- Cylinder bore diameter and condition
- Cylinder taper and out-of-round
- Piston-to-wall clearance
- Piston rings and ring end gap
- Connecting rod bearings
- Connecting rod bolts
- Crankshaft main bearings
- Crankshaft journals
- Cylinder head and valves
- Valve stem seals
- Oil passages and lubrication system
- Powerhead gaskets and seals
