    Although this is the first time I've seen this test, I knew this was happening from experience. Lock washers are fine on things that don't get a lot of vibration, which is not the case in these engines we use. This is why I'm so adamant of 1) using lock tite (on studs), and 2) the use of double (jam) nuts and or a nut (jam) and self locking nut. Being around the aircraft industry most of my life (50 years), as a son of a aircraft engine overhauler, a systems installer, pilot, and Air Traffic Controller. In fact if I had access to the proper hardware I'd also safety wire certain fasteners. ALL (removable) aircraft hardware that has to do with the engine or airframe either are safety wired or use self (nylon and others) locking nuts. Think they know what they are doing...ya think?

    I changed my clamshell sprocket over to standard bolts, use lock washers and nylon nuts.... It still comes loose! Just a reminder for you guy's to check!!! Don't want a chain lockin you up!

    I can usually tell by the sound when I'm pedaling. You'll hear it's time to snug them back up by the noise the chain makes on the gear. It will sound out of round!
