PISTON RING GAPS The rings should be checked in the cylinder to ensure that the end gaps are sufficient. Drop in ring sets typically require no adjustment to end gaps, but MAHLE recommends that the rings be checked for minimum end gap. File fit rings require individual gap adjustments to the top and second rings.
The mahle Original® repair pistons are ready for installation with mounted piston rings. Piston diameter, installation clearance, and if applicable – direction of installation are marked on the piston crown. The stated piston diameter added to the corresponding clearnace gives the cylinder diameter.
Performance rings. MAHLE pioneered the use of piston ring simulation and computer development tools to engineer rings that provide “free” horsepower by successfully minimizing friction. MAHLE’s ultra flat ring flanks and precision finish also maximize ring to piston sealing.
Featured are MAHLE Motorsport's tech video's and instructional video's that offer an in-depth discussion into the latest in piston technology. The Compression Ratio Calculator and Ring End Gap Instruction Information is also available for download.
Performance Piston Ring Fitment. The AERA Technical Committee offers the following information on fitting piston rings for performance engines. This information is also supplied and supported by the Mahle-Motorsports company.
