2012 Recon engine rebuild question

New to the forum but not engines. Rebuilding my TRX250TM and when I bolted the front cover on covering the clutch and centrifugal clutch the cover bolted down and torqued. When I tried to run it through the gears it wouldn’t do anything and the clutch adjustment would not move at all. As I was turning it around to unbolt the cover something popped in the rear cover and all of a sudden everything was fine, it would run up and down through the gears and spin freely and the clutch adjustment found be moved properly. It sounded like something seated but it just has me bothered lol. Before bolting the front cover on I had verified it would run up and down through the gears. Think I’m ok? Anyone ever have this happen to them?

Thanks, Tom
