Shop Yamaha 90HP Rebuild PartsWhen to Use an Oversize Piston
An oversize piston is used when cylinder wear, taper, scoring or damage requires the cylinder to be machined larger than the original standard bore.
The cylinder should first be accurately measured to determine whether it can remain standard, be bored .010 or .020 oversize, or requires installation of a replacement cylinder sleeve.
Parts to Inspect During an Oversize Piston Rebuild
- Cylinder bore diameter
- Cylinder taper and out-of-round
- Finished piston-to-wall clearance
- Piston rings and ring end gap
- Connecting rod condition
- Connecting rod bolts
- Connecting rod bearings
- Crankshaft main bearings
- Crankshaft journals
- Cylinder head and valves
- Valve stem seals
- Oil passages and lubrication system
- Powerhead gaskets and seals
