Greetings,
My 2020 800XC machines continue to give me problems (battery, starter, sprague gear, gauges, ignition.....).  Now it's the cam chain tensioner.
I would appreciate any info/suggestions as to why the plunger on the chain tensioner melted.  It was leaking oil, so I removed it; only to discover the plunger was melted ("welded"). 
Thank you.  Stay safe

Greetings,
One of my 2020 800XC machines has another problem (one of MANY!!).  The cam chain tensioner was leaking oil; I removed it to discover the tensioner was melted.  It cannot rotate/move.  Any idea as to why or what caused this?  When the replacment is delivered, what, if any, special steps do I take for the instalation?  Thank you.
