Here we go for round 2 of the neutral rattle challenge. In this corner, the Baker Street Door, in the opposite corner is the HD cast door. May the best door win! As some of you remember , I installed the '17 Scissor low gear out of a '17 in my '16 hoping it would reduce or maybe cure the infamous rattle. It didn't make a difference unfortunately. What it did do was make it almost fall into low gear with out the big clunk especially when I used Redline primary fluid, at least I got something out of it ..lol
After talking to both Mark @ Baker and John Sachs. I found out there are two weak links in the HD 6 speed. Trap door bearings that are moving back and forth and the main drive gear. As a lot of you know with all helical gears ( except low) and a main shaft that weighs 5.83 lbs that's a fair amount of "swinging beef" back and forth. Both the counter shaft move laterally back and forth as they are "fighting " each other so to speak.
With a weak cast trap door and snap rings that compress, the bearings and other things move around when the shafts move back and forth laterally. Not a good situation. Especially when you have more cubic inches (110) + combined with the pulses of the motor when idling, I can certainly understand why SOME rattle. I'm not too sure all of them don't rattle to some degree. Just speculation on my part and I may totally off on my theory.
After another conversation with John Sachs What i decide to do this time was add the Baker Street Door. Plus install the new MDG & MDG bearing I mentioned in another thread and new inner primary bearing and race. Gear set is currently out, other parts are ordered hopefully I will get to slip it back together next weekend and we will see. Mark & John both said it may not totally eliminate it , but it should reduce it.
i just had enough of the damned rattle. Have a fresh 117 and I'd like it half way quiet. Guess the good news if the lifters start rattling, I won't be able to tell..lol At least the Baker Door is chrome and it will look nice!
Damn I didn't want to know this much about the HD 6 speed..oh well...the story goes on..stay tuned

Yea thought about that too Don..May have to try some of Jerry's secret sauce with special noise dampening particles from a secret location deep in the woods of Indiana..Already have a marketing angle on that!...If this works ..baker doors may become very popular..or the damned sauce...

Anything Baker is top quality, and that looks like a robust unit. Curious to know if this solves the problem.

The Baker is US made but why are they using Japanese bearings? Are they superior to any bearings made in the USA? That would be an interesting question to ask.
I enjoy these type threads not necessarily for something I want to dive into but for the repairs/fixes/aftermarket company engineering that is required to make our HD's run/operate as we expect instead of how we purchase them....good luck with the rattle reduction, Tex.... :2vrolijk_21:

Boy Howdy.!.. me too! thinking it should be at least quieter...

Baker Door & Shift Drum Installed Along With '17 "Scissor" Low Gear. Now if work will just slow down a little we'll see if this either fixes or reduces the rattle. Guess if it doesn't it will look damn good along with the new chrome inner primary. If it isn't quiet..it will look good!

Hey Tex!
Any word on your transmission project?

Hey Tex!
Any word on your transmission project?
Yes ! , Fired it up Saturday, pretty quiet on the lift. Took a 50 mile ride yesterday , banged on it pretty good. Looks like the door did most the deal. Still noisier thanI like hot in neutral at idle I noticed a little compensator rattle at idle ..grrr , should have checked the spring stack height when I had it down, missed that. Guess that's the little stuff you miss when you are a weekend warrior vs doing this for a living. lol . Overall it was a lot of fun and one hell of a learning experience!
No biggie, warranty will take care of the comp and will put some miles on it,later this week probably this weekend, and bang on it again. Just want to make damn sure the door took care of everything ,before I post the final result. Overall I'm pretty pleased , with the door and the new Baker shift drum ,it shifts like dream in addition to being much quieter .

so you only changed out the trap door....or you have a list of parts

I "fixed" neutral rattle on a 2012 RGU, a 2014 SGS and a 2012 CVO SG by just using a good synthetic transmission gear lube. This post is not to stir the pot, just saying what worked for me.

Really don't have a parts list. I just changed out the Baker door it also comes with a shift drum. Picked up the stock door next to the Baker, no comparison, it's like a friggin paper weight. We also slipped the "scissor' gear in there out of a '17 . PN 35600103 $47.81 . Now it Drops right into gear, nice . Very pleased with the outcome....Finally!

I had also heard that before I did anything I tried Spectro, Redline , Formula+ still rattled . Was very tempted to try Jerry's sure fire cure...hand full of sawdust.

Trans update came out good, got most it. Still not happy with it. Scissor. Gear slips right on when changing door. Would buy a new needle bearing while I was at it. You will like that mod! Nice and quiet not perfect but a great improvement.
I have another gear set I got from a 2010, going to freshen it up, put the Baker door on and see what it sounds like. I have changed everything EXCEPT the gear set from the compensator in chasing this noise. It's almost Jan.,no racing to watch , just as well get some garage therapy..lol
If you pull it down I would damn sure install the new final drive gear single roller bearing .That's the other change in '17. The old double roller bearing has been a POS for a long time.
Tight primary chain, tight drive belt coupled up with a 14 lb clutch assembly flopping around on the end of the mainshaft makes it tough on that bearing. I posted up part numbers in another post.
