LF200GY-5 Transmission doesn't shift
2007 LF200GY-5 / 1064 km
Transmission won't shift, shifter moves but doesn't feel right, clutch works. Bike will move under it's own power, just can't shift gears... Removed kickstarter, rear brake pedal, disconnected clutch cable, thirteen (13) 8mm bolts securing clutch cover/case. Tapped on cover/case with wooden block until it broke loose from gasket... gasket was undamaged and reused. Found the bolt that secures stopper-plate to shift-drum loose and partially backed out. Stopper-plate no longer engaged pin mounted on shift-drum, or spring loaded stopper-arm (with roller) that holds transmission in gear. Used circlip pliers to remove circlip holding gearshift plate. (circlip, spring, then plate) Removed gearshift plate, bolt that secures stopper-plate, and stopper-plate. Held stopper-arm out of the way so stopper-plate could be positioned to engage alignment pin on shift-drum. Used thread locker on bolt and secured stopper-plate to shift-drum. Make certain the roller on stopper-arm rolls against stopper-plate. Replace gearshift plate, spring, and circlip... I used anti-seize compound on bolts during installation of clutch cover/case. Grease shaft on brake-pedal when you install, and use new cotter pins. Start to finish was four hours, including lunch break, pictures, clean-up, and test ride. Bike is now back in everyday service, shifts better than new. http://i226.photobucket.com/albums/d...0239Medium.jpg http://i226.photobucket.com/albums/d...h_DSCN0241.jpg |

Phil, Thanks for taking the time to put this all up in post. Isn't that the new counter balance shaft engine?

Great Post!
Very clear and concise. Fantastic pics. I think this could be kept in the tech info section permenantly. :wink: |
Very cool post. Learn something everyday.
|
Good deal, and the best part is you fixed it yourself. Nice work and thanks for sharing.
|
Great detailed post. Thanks.
|
Nice job, thanks for the detailed post...
|
Thanks Phil,
It is posts like this one that make "China Riders" so important for all of us. |
I created a sticky for great post like this. This one has been added.
Thanks Phil Allen |
I have been having this same problem (occasionally) with my 85 Yammy Big Wheel, and after reading Phil's experience, I am tempted to tackle the problem with Papa Bear myself -- I strongly suspect that the basic engineering of the shifting apparatus is pretty close on all bikes -- I could be wrong (It wouldn't be the first time).

It's located sideways by the clutch casing. So when the casing is removed the location is lost. There should be no more than about .5 mm sideways movement of the shaft with the clutch casing fittted. The correct gasket is important here, I used some thin gasket paper and the selector shaft was pinched and it was difficult to change gear.

Right here goes, the selector shaft ("shifter plate and shifter bar/axle thing"), to put simply, is trapped in place by the outer casing. As the outer casing has been removed it's now free to slide out.

I have a Hensim HS250DB enduro that I bought a few months back. I've rode the crap out of it and it's been a great bike. The other day I was changing the oil and when I replaced the dipstick/oil plug I heard a snap! I backed it out and the little plastic piece at the end of the dipstick had broken off inside. I'm trying to get the cover off to retrieve the piece of plastic right now but after taking out (12) 8mm screws, the brake pedal, kick starter, and releasing the clutch cable the cover won't budge at all. I've tapped on it with a hammer and a piece of wood but it won't break free. It feels really secure like there are still screws holding it. I've looked everywhere but only found 12 screws. Is there 1 more that is hidden or something. Anybody have any advice?

Glad you got it worked out.
Please tell us more about the bike if you will and how you are doing with it. Lots of interest in it earlier. Thats a good looking bike. Thanks for the pics too. |

I have that same problem sometimes. Looks like I'll be looking at that bolt. Thanks for the post.
I know it's old but... lol |

Cool... the original post pictures are the same engine I have. Useful to see. Hope I don't experience this issue, but if I do... looks like it's an easy fix.
Cheers! |
It might be a good idea to Loctite the bolt in proactively.

I just took mine out and used red loc tite. Don't think it will come out. haha
After I screwed back in I shifted into 1st then tried 2nd. (Not holding the clutch in since I had the clutch free floating until I get the special socket) It wouldn't go into 2nd. I'm think because I don't have the clutch together and the clutch lever pulled in. Not sure.? I took the screw back out wiped the red loc tite off and put blue loc tite on the screw but now I can't screw it in. Looks like I have to align the holes up to. Anyone taking this screw out try to make sure you don't move anything. lol Well looks like I'll have to wait to get the tools to align it up. Can't do with the clutch on. Just my luck. I should of just left the red loc tite in. And worried about it if I couldn't shift into 2nd with everything back together. Oh welllllll ... haha Dan |
Yeah, it would take awhile to get where you want to go, if you only have one gear.
