Professional Piston Ring Friction Pull Measurement ToolMonday, December 19, 2016

Traditionally, ring selection has been more art than science. Now, the patented Professional Piston Ring Friction Pull Measurement Tool (P/N 67657), gives the Engine Professional (Performance, Diesel, Heavy Equipment and Hydraulic fields) the data they need to make get it right. This is an analytic and diagnostic tool like nothing else on the market.

Recording precision cylinder ring analytics, using this tool, builders can fully optimize engine performance and identify flaws before the engine is built. A digital load cell, attached to a patented adjustable fixture, allows a builder to perform the precision cylinder ring analytics by isolating the ring, and pulling it through the cylinder (prior to piston-ring assembly), for a precise measurement of ring drag against the machined cylinder surface.

The Professional Piston Ring Friction Pull Measurement Tool gives engine professionals the ability to:

  • Facilitate engine cylinder ring preparation prior to assembly, which aids in evaluating cylinder bore surface finishes (Ra, Rz,Rk, Rpk, Rvk taper)
  • Compare cylinder quality in the machining preparation stage
  • Accurately measure the consistency of cylinder ring manufacturing (verifying ring set)
  • Balance ring drag from cylinder to cylinder
  • Diagnosing cylinder ring failure after usage
  • Manage friction coefficients for build sheets
  • Analyze lubrication efficiency, and help predict engine temperatures
  • Measure all of the above with the torque plate installed, potentially exposing cylinder deficiencies prior to assembly

With the Professional Piston Ring Friction Pull Measurement Tool you will get it right, and get the trophy!
