Transmission Bearing Failure Question

Greetings
The transmission in my 2010 FLTRX started growling at me in gears 1-5, and then got (eerily) quiet again in 6th ... And the oil came out looking like chromed pudding. I'd heard these things have a tendency to fail in the 35,000 mile range...but I was hoping the previous owner had already gone through that part for me. However current indications imply otherwise...

On a brighter note, another member here just so happened to have a complete (2012) replacement tranny that they needed rid of, so we able to help each other out. Which brings me to the question. Should I replace the - apparently (quite) common failure point - offending bearings in the new tranny before I put it in? ...and if so with what?

It's an ultra low mileage tranny in perfect condition, but if the main shaft bearings are really that prone to fail ...(current indications being what they is)... Since I'll have it out and in my hands before putting it in ... would it behoove me to give it a better fighting chance of a long(er) life to give it a different bearing?

Thank you,

Stoic Joker

Their easy enough to change, I'd go for it .Just rebuilt my 2010 6 speed because of said bearing.

Understood ... I wasn't worried about the level of difficulty. I was just looking for options on where to get what bearings. The dealer will have the stock bearings ($200), but are they new and improved enough to not -(be from China)- suck? Then there is the highly recommended Jim's bearing (/rebuild) kit ($460). I was just hoping someone knew of something between those two options that would be better than stock, yet less than a bundle.

e.g. I want it to be right, but I ain't exactly had time to budget for this action ... Ya know?

Just guessing but maybe the Jims kit would be the better option, you know the old saying "you get what you paid for". I would just look at the trans fluid in the trans you acquired and see what it looks like, the bearings may be good in that trans. My 08 has the original bearings and over a 100,000 miles on it with no problems but I used 75w140 full synthetic gear lube in the trans since the bike was new.

Yes, but there's another one about not being able to get blood out of a turnip ... Which is to say this little surprise didn't come with time to budget for it. So the money just ain't there for it. I'd love to go that route, but... Turnip.

No case to drain, just a gear set with shafts in a trapdoor. From what I've been hearing, and according to the HD parts guy that was looking up the service history for the input shaft bearings ... They weren't worth a shit from the factory. So I'm a tad nervous about tossing in a second set of the same thing that just went kablooey.

I ordered a complete set of - hopefully updated - bearings from the dealer ... So I should be good for another (at least) 30,000 miles. I'm just not incredibly warm and fuzzy about how far (and if...) I'll make it past 50k with another set of HD bearings.

Hence the attempt at finding a mid-range third option.

I don't know about the previous owner, but I'd been running the HD Synth oil in mine, and it was always just fine...right up until it wasn't. It went from clear as a spring day to chromed pudding somewhere on the run.

What bearing failed?

If it's the main drive gear bearing, which was poorly engineered, Baker has a fix for that. Replace that double row ball bearing with a Timken set.

If its the needle bearings, then something else is up. Same for the trapdoor bearings. Generally that,s contamination from milled parts or lack of lube.

Holy Crap, $600.00 for one bearing?!? ...... That's not in the budget.

Given that it growls in 1-5, and quiets in 6th, I'm assuming the main drive gear to input shaft needle bearing have taken a shit ... I haven't had time to tear it down yet - That's for tonight. But from the dealers reaction, and a look up of the part's service history, the needle bearings in question were also quite fail prone back in the 9-12 year range (mine is a 10).

Lube was there, and the tranny's never been opened since it left the factory to the best of my knowledge (no history under the SN).

Update: After doing the tear-down, and getting eyes on the internals. It was the double roller main bearing that failed and not the needle bearings on the input shaft. So why the hell it got quiet in 6th is a complete mystery to me ... but apparently - since everything else looks/feels clean and smooth - I now have a complete spare transmission.

Shit...

Glad you got it fixed! It never hurts to have spare parts either.

When in 6th, the bearing has gear load as the main gear tries to move outward. That was prolly enough to quiet it down.

That bearing is the most common failure in the cruise drives.

What lube was in the trans? Early on some MoCo dealers tried to blame it on Shockproof gear oil. But many indies are saying it's a Syn3 issue. Personally, I think it bearing from the lowest bidder.
