Timken conversion
Hello all,
Before responding please, ask yourself, "does my response include a fact based answer to the specific question asked?" If the answer to that question is no, please refrain from commenting. Opinions are great things, but that's not what I'm looking for today. If you don't know how to help, start with staying out of the way.
I was planning on doing a timken conversion on my 09' FLHTCU. Another rider I was speaking to said that when Harley went to the left side roller bearing they also began having the left and right case halves manufactured separately and as a result the left side bore is often not true and needs trued to the right side before the conversion can be done.
I hadn't heard this mentioned in the YouTube videos I watched or a few articles I read. So, naturally I wanted to check with some other folks on this.
Thank you for the feedback

When it first happened many people thought they were cheaping out myself included you don't hear as much but I am not sure what other changes were made
I wondered if that could have caused bad stator seal
It is why I am reluctant to do more than stage 1 on 96".
Bike is old now and high Mike. Not sure it is worth dumping money to hop up. Not saying I wouldnt.
Dark horse is known for conversion.
2002 was last year timken followed by cheaper cranks

While I appreciate the feedback, what I'm looking for is less of an opinion of if it's worth rebuilding and more the facts of what needs done to do the best job on the rebuild. More specifically, if the left side bore needs trued or not and if so, where such may be done. I am confident I don't have the proper tools for such.

Changing to an S&S flywheel set of course makes the tapered bearing set mandatory.
One of the sponsors on this forum can do the tricky stuff for you:

Thank you for the reply, but again: I'm looking to get a specific question answered, which you too failed to do in your response.
The question is:
In installing a timken bearing conversion, does the left side bore require trueing to bring it in proper tolerance of the right side?
