Transmission

[roadsterrick]

I did not see any posts on this topic, so here goes. My bike's problem appeared without warning. After I pulled away from stop, I shifted into 2nd, but nothing. I could go back to neutral then to first, but again, no 2nd through 5th.
After a $400 tow home, I've begun disassembly of the rear by pulling it off by the swingarm, since I want to replace the u-joints, and perform a general inspection as I work my way forward to the transmission.
I will post my progress as I go along.
2002 23k miles
cheers, roadsterrick.

sounds not good ;(

Man, that seems early (23K) to have such a major problem. I hope you figure it out.

Sounds like it may be a broken shifter fork, youll have to split the engine case to get at them. Its a big job depending on handy you are and how good a tool set you have.

Before you start ripping the engine out to split the case, you might wanna check the shifter linkage for something bent or loose or falling apart. There is a linkage from where your shift levers attach, back to the front bevel gear cover. You will have to pull the outer cover off the left side to have a look at this linkage. Also under the front bevel gear cover there is more shifter mechanism which could be at fault. Pulling the bevel gear cover is a major job in itself and would involve unbolting the rear of the engine and raising it up some. You might wanna hve someone help you and for sure, a manual should be on hand. Chances are Ringadingh is correct about a bent or broken shift fork. It is a problem that happens quite often. Hope you find an easy sollution to your problem!

Welcome to the site from the Great State of Texas. Good luck with your project and if you need help this is the place to come.

I 2nd Lomax... I had a small branch off a tree jam my shifter linkage up where I couldn't see it..

Since I ever heard of Nomads, not once have I see a blown tranny yet..

[nomad]

my yamaha did this..there was a small spring under the cover that brought the lever back up, enabling it to move to the next gear...without it, i couldn't shift. i hope this helps. good luck!

[blowndodge]

nomad, I'm thinking thats it. 23K and shifting forks breaking doesn't sound right either but it could be Ringadingh..

roadsterrick: When you shift from 1st to 2nd through 5th, can you feel it shift each time? If not, it's probably the return spring or somethink it hanging up externally. What feels like shifting 2nd through 5th could be handing up in neutral and what you think is shifting through the gears is not!

4 cogs all gone at once is theoretically possible but you first would be gone too.

Pull the left side cover and have a peek.

Do you have a neutral light? Does it work? when you shift out of first and try to hit second is the light on?

Not being an expert, I agree with the return spring being the culprit. Will be watching to see what you post as to what it was.

[roadsterrick]

My second post.
BLOWNDODGE~~~I feel the shift from 1st to 2nd, and neutral light off. From 2nd to 3rd no clunk, neutral light still on. No matter how many attempts to 3rd, 4th, and 5th, nothing but smooth clean shift mechanism arm movement, but no clunks. So, I agree that I'm still in neurtral.
RIDEMSLOW~~~~the return spring does pull the shift arm back to the normal position automatically every time.
RINGADING~~~~~according the clymer m471-3 manual, there is a 3rd, 4th, and 5th gear shift fork. Since I can't get to any of these gears which fork is bad? Wouldn't you all agree the odds of these forks failing at the same time would be remote? Also, the manual does not show a 1st to 2nd shift fork, as yet I don't understand...
LOMAX~~~~~~~~I don't see the linkage in the manual that runs from the shift arm to the bevel gear assembly that you referred.
My next action~~~I'm going to take the advice and pull the left side cover, and examine the shift arm, spring, and shift mechanism arm attached to the spring, and where it contacts the shift drum. At least for now I don't have to pull the entire engine for this inspection, and it seems like a logical first step.
.............thanks everyone for the replies.

before i pulled anything I would lay on the ground, flat on my back and have a hard look at the linkage which is exposed but out of sight if you are not layin on yer back.. There are atleast 2 bell cranks exposed.

[roadsterrick]

My 3rd post.
MACMAC~~~~~~~~yes, I could not see it very well so I jacked my table lift higher to access it. It is all in one piece, and attached. I originally did not realize it attached to the crank on the bevel gear assembly as Lomax suggested. Schucks, I wished that was the cause. I've begun removal of the stator cover, but that's it for tonight. Looks like this is turning into an elephant of a job. As long as I can take small bites every day I'll be encouraged. Cheers.

[blowndodge]

If your still in neutral all may not be lost. your return spring mechanism may be at issue

[macmac]

Ouch, I was hoping for some external problem..
