Use the chart below to determine the minimum ring end gap. Multiply bore size x ring end gap factor. Example: For a naturally aspirated street engine using a cast piston with 4.000″ bore, the top ring end gap would be 4.000 x .004″ = .016″. The second ring end gap would be …

Modern piston design locates the top ring higher for improved requires a larger top ring end gap. To find the proper ring end gap, multiply your bore size by the ring end gap factor listed on the chart (i.e., Street Naturally Aspirated 4.000” bore x .0065” gap factor = …

The following chart indicates the specifications for compression ring gap as outlined by the Society of Automotive Engineers (SAE) as standards for the automotive piston ring manufacturers. Safe, Recommended Automotive Compression Ring Gap Clearances

Always inspect ring end gap during the assembly process and make any adjustments before final assembly! As a general guideline, ring end gap that is larger than expected is less of an operational concern than too little end gap.

Mar 13, 2015 · The following chart indicates the specifications for compression ring gap as outlined by the SAE (Society of Automotive Engineers) as standards for the automotive piston ring manufacturers. An important fact to remember is that the manufacturers rigidly adhere to these tolerances and that the ring gaps are inspected in gauges accurate to .0001 ...

2. The piston ring should be below and square to the deck. 3. Measure ring gap with a feeler gauge or equivalent measuring device. Important: Ring sets are manufactured to fit specific bores. For every .001” over the intended bore size, ring …

Wiseco Piston Ring Gap Quick Tips As a piston moves down on the power stroke, combustion pressure accumulates in the land area of the piston (between the top ring and the 2nd ring.) This accumulation of pressure can cause the top ring to unseat from …

Below is a chart which contains the recommended end gap factor. To use this chart, multiply the bore size by the ring end gap factor to obtain the minimum end gap which should be achieved. Example: 4.000” bore street engine with cast piston the top ring end gap factor is .004”, thus 4.000” x .004” = .016” minimum end gap. It should be ...

Ring end gap should be measured with the ring square in the bore on a fresh hone. Cylinder should be free of any taper. Use this chart to determine the proper end gap for your engine.

Modern piston design locates the top ring higher for improved requires a larger top ring end gap. To find the proper ring end gap, multiply your bore size by the ring end gap factor listed on the chart (i.e., Street Normally Aspirated 4.000” bore x .0065” gap factor = …
