Here is a puzzler for ya! I need to finish reassembly of the front cover after chain and rail replacement and I need the tightening value for the lower right guide rail. Part #117 050 18 16

Its attached with two bolts with spring washers and get this - they were only hand tight- when I removed them! The manual has no torque value and does not mention - hand tight!

The rail seems to flop around a bit when the bolts are loose and when tight the rail is stationary. Would that be a problem? Are they supposed to be loose so the rail "moves" to take up slack in the chain?

Would Locktite be a good idea on the bolts? I would hate to leave them -hand tight- and then have the bolts back out from vibration and cause a chain snap.

Someone must have some thoughts on this one.
