I was asked today to provide some information about the "flywheel bearings" used on a particular industrial/marine engine. The customer wants to know the size/material/type for the engine bearings (main/thrust/rod/pin) and in th.e same list he includes "flywheel bearings." Later he asks whether the flywheel bearings are "manual" or "air jack."
The only kind of flywheel bearing I can recall seeing is the pilot bearing used at the rear/center of the flywheel to locate the transmission shaft when a clutch is used. We don't have any of those in our flywheels. I don't know what "manual" and "air jack" would mean in that context, either, unless they're removal methods for the bearings (and even then air seems an odd method vs. hydraulic)... anyone familiar with what this guy is after?
