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
