Do you know if the tranny is "fixed" if the problem is corrected...Im not worried about BDM they always take care of the fix, I just wonder if this will continue to be a problem...

Great, I hope it will be soon...waiting by the phone to hear from the vet to give me the good news(fingers crossed)...the call should go like this..."hey, your bike is ready, only a minor adjustment, nothing broke, your good to go!"

This is my second Big Dog and it has been running perfect for 7000 miles...and then it just quit...

thought he said that he had the same symptoms as Skully's and my bike. May have mis-read but, that's what I thought I read above.

Creeping when in gear etc. sound like the clutch hub issue. Losing power to the ground and the clutch at the same time == mainshaft broke.

Hello Everyone...I'm new here, I was intesested in this because yesterday 6/17. I was on the freeway cruising around 65mph...went to pass, pulled in the clutch and felt like the cable broke..but, the tranny went limp...engine revs as if in neutral...I was able to coast to the shoulder and put bike in neutral(green N)...cluth cable has slack but tranny will not engage...needles to say flat bed to the shop...

6950 miles... 07 chopper...wtf
Gas, based on this post, I'd say the man has a broken mainshaft....

OK... will note that in the mental file. Now that you mention it, I remember Jake saying creeping when carrier went out.

What kind of tranny fluid are you running and is your bike stock?

Unfortunately, I've had both problems.......

When my hub broke, the bike was hard to get into gear and the thing would creep when in gear.

When the mainshaft broke, I lost power to the ground and it felt like I broke the clutch cable, no tension on the clutch at all.... it was just flopping around.

TCALZ07...

My bike is stock...the fluid was replaced at the 5000 mi service by the shop...I'm not sure what they used...I will find out and let you know.

Has anyone had the mainshaft broken twice on here? Does BDM have an upgraded main shaft?

Watched some Vids on here by Ray...There is one were a Big Dog is riding a wheelie after a burnout...Nice show of power....Just wondering if he had the Baker DD6? I want what hes got!

This sucks and you're one of the only 07's I've heard of.

If you can ask your dealer if they can verify your alignment is correct for your trans before they remove it and how do they do it. Such as tools and process.

My guess is a lot of these dealers don't do what they are supposed to do from my personal experience and others

TCALZ07...Agreed, Couldn't have happened at a better time...I just hope that I can get the wrenches working on it...I dont even have a diagnosois or prognosis at this point...with riding season in full swing the wrenches are at a premium.
From what I've read around here it wont be good news, But, im ok with that, as long as I get it back soon and the problem is not recurring...I will try to get some answers to your questions and post them...But, like I said I still need a wrench at this point...

I've looked around this site and I cant find that this is a recurring problem once its replaced, but if they are putting the same mainshaft in, I would think that it could be...Maybe the lightweight and compact tranny(Baker) is not the best combination after all...although they seem to really have a large market share...

I searched around other sites(no bike, I have time now) to see if this was a problem with the Baker system in general and I wasnt able to find anything other than praise for the system...Baker is Da Chit...

I don't think anyone has enough miles on their replaced main shafts to know.
I've only been around since Sept 07 but this whole tranny thing just seemed to pop up quick.

I've heard the idea that the 300 tire is causing it but I think the 300 has been around for 2 years so why now? Some are saying bad metal but I would think there would be more then.
I'm guessing it may be a combination of things but I'm wondering about Alignment of the trans.

Update...Add me to the list...My '07 stock chop w/7000 miles has a broken main shaft...BDM has given them an RMA# (good news) so they are pulling the entire tranny as a unit(so no pics of damage) and sending it back tomorrow...Is that the proper procedure? I thought they could pull the gears without removing the entire unit...and get a new gear set and plug them back in...to simple I guess...

Mechanic confirmed (over the phone) that the tranny was in proper alinment was within specs and that there was no wear to the inner primary, that i've seen with other owners on here, thats more good news...

WOW... they are dropping like flies and making me nervous!!

The wear on the inner primary is the broken carrier problem... different issue..

Thx Gas...
I only mention the inner primary wear because there was a question earlier about main shaft flex being an issue...
Also the mechanic stated that since the tranny has id#'s on it they have to send the entire unit back to BDM...I thought they would pull the gear set and replace it...what is standard procedure?

SOP from what I can tell is just like you said... they send them to BDM for fixing. Not sure why... BDM must figure most of their field mechanics aren't tranny experts. IDK

Mine had about 6,500 on it when it went. I got it back last week and don't think it was the unit I sent in. It's scratched and dinged up, and the belt drive is rusty in one spot like it had been sitting. Mine should have been all clean as I had ridden over 150mi the day it went out. It looks like someone had hit it a few times around where the input shaft seal is and I am not so sure that you could get another seal in it since there is a nice burr on the inside of seal area.

It's going back to the dealer in the morning to have them take a look at the damage. I hope I don't have to get any more pissed off about this than I already am. I've been down over a month now. *&$(#)@$!

That and I sent it in with the shift lever still on the danged thing, as well as the speedo sensor and neither of them came back with it. The dealer is trying to make this part right.

I was told by the local tech, take that for what it is worth, that they cannot get the tools to open the trany until they take the required training from BD. That is why they are having to send them in.

This is for the guy asking about shift pawl adjustment.





Piece of cake Lee!

Can the bike shift when it isn't running?

IF you raise the shifter does it return to it's normal position or does it flop?

If it flops your shifter pawl spring could be broke...it happens!

You have to be able to get the bike into third gear to do this adjustment.

Put the bike in third gear and disconnect the shift rod from the lever on the tranny.

Move the lever fore and aft and you should feel equal movement and spring tension going either way (you may feel a bit of freeplay before feeling any spring pressure but it should feel the same both ways).

Just forward and below of the shift arm you'll seen a nut with a threaded shaft sticking out of it. This is the shifter pawl adjuster. It has an allen head on it so you'll need an allen wrench (may have to shorten it a bit if clearance is a problem...I don't remember off the top of my head what size it is I'm thinking 1/4" but could be wrong)

loosen the nut and rotate the adjuster either way until the adjsutment feels the same both waysYou shouldn't have to go more than about 1/2 a turn either way. when all feels good, tighten the nut and reattach the shift rod.
