09-16 TC flywheel/crank issues
Hey everyone, I have been curious the past few days about anyone having crank issues within these years on their bike or bikes. I've scoured the internet and several other Harley forum related sites and see that most people stop talking about these flywheel/crank issues around 2012'ish. Also, curious for the new M8's as well. A lot of people doing motor builds and I don't see many addressing the flywheel/crank. I'm sure runout is/was measured in these builds, I hope. Just want some 2019 info on this, thanks for your input.

The crank / rod bearings went bad on my 2009 FLHTCU @ 65,000. Crank was replaced with SE Flywheel Kit '06 (# 23729-07A) @ $729.95. The complete bill was $3300 covered by ESP. The same bike had the right side crank bearing walk & spin in the case @ 99,000. ESP covered another $3300 in repair including cases & a crank. Now the good news is that my 2014 FLHTK has only had a rocker box gasket replaced so far and it's @ 114,000.

Thanks for the info guys, would still like some more replies. Like I said, seems that this issue hasn't been as prevalent as it once was. I've been wanting to do a build on my 09 RKC, and have been researching the past few days, its been snowy and its gonna be very cold this week. My garage is not heated so I'm hoping to tear down and check out the gearbox and crankshaft pinion runout next week. I've been talking about doing a 107 build, however that being said, if the crank pinion runout is bad, gonna go with a new S&S flywheel, and that just about kills my budget this year at $2000. If I do the new flywheel, I'm gonna go bigger and I'll have to save more money.
Once again thanks for the replies.

My 2008 spun a wrist pin bushing at 10,000 miles. Then at 50,000 miles it had a crank pin and bearing go bad. Both times, I had the crank fixed by Darkhorse.

When I upgraded my 110" motor to the 117" Pro Race Big Bore Kit, I sent my Crank to Dark Horse to get some love.
In addition, upgraded every new part inside the motor and added a SE Timkem Bearing. It made a big difference performance wise.

I've read good things about Dark Horse, however, there is an S&S video that debunks the welding of the crank pin press. Does it work, yes, but in the long run, I think that is just putting a band aid on it when it needs stitches, my opinion. If you spend $1000 to have that work done, might as well spend $500 more and have a brand new flywheel with no worries, wouldn't you think?
