Found V Drive shaft bolts loose...

[Wrenhaven]

During winterization cleaning I noticed that the bolts that hold the drive shaft to the V drive are loose, like I can turn them with my fingers!? I found one loose while cleaning oil off the bottom of the V drive unit, then found that they were ALL loose! Surprised I didn't have a vibration or noise during use. It's hard to see so I took my phone and snapped a few pics from underneath...



I can spin all of the silver bolts freely. Does anyone know the torque spec for these bolts? Sounds like I need to go around and check all my bolts now!
