Recip Compressor: Piston & Rider Ring Wear
Recip Compressor: Piston & Rider Ring Wear
(OP)
Due to various reasons, our rod-drop measuring capabilities are not available. What would be the best way of tracking piston & rider ring wear for a study? Some have suggested using a feeler gauge to measure the top clearances but this only gives you the sizes of the outermost (crack-end) rings. What would be the best way of assessing the ring wear rates without rod-drop facilities?
The goal is to trend the ring wear & then extrapolate to predict the ring life.

RE: Recip Compressor: Piston & Rider Ring Wear
It would probably be easier to measure the rod run-out. As the rider band wears and the piston drops, the run-out will increase. This can be measured with a dial indicator and does not require you to pull the outer head.
