I need some help on this one. I have a 2010 FLHTCU with 25 K , the primary bearing is making a thrashing sound. Harley Tec said it was going out. I am going to perform the trans bearing and primary bearings and seal reinstalls. My mind bender is why did it go out in 25K , the reading is pointing to the primary chain slack adjuster. It gets to tight and put excessive pressure on the primary bearing. I have been looking at the baker chain tensioner. Should I install the Baker chain tensioner and the high tourque primary bearing and seal or just stay with the Harley stock. Any ideas appreciated . I have done all maintenance myself to the book. I am a mechanic by trade. Thanks in advance.
