Piston Pin Side Clearance at Bob Campbell blog

Piston Pin Side Clearance. There must be sufficient pin clearance, so the piston can rotate freely while it is under compression, ignition pressure, and during the “pull and push” from top dead center, and. Some original equipment engines may allow as much as.002 to.0025˝ of side clearance for the rings in their grooves. Between the clearance point and. The highest load area on the rod is always on the bottom of the rod eye and the bottom of the pin, especially on the comp stroke and the power stroke. Side clearance between the ring and piston groove is easy to measure with a feeler gauge. With flat pin clips,.005 should be. This allows the engine builder to use narrower connecting rods and bearings. Minimum clearance is determined by the pin length and wall thickness as to how long it retains its heat longer than the piston itself. This approach minimizes rod side movement with tight clearance between the small end of the connecting rod and the piston pin bosses. Most rings for performance applications require.001 to.0015˝ of side clearance.
