Flywheel Side Movement -T5

[Stovie]

So posted t he other day as no spark, this turned out as dodgy big of solder on the stator. So when putting everything back it started, but sounds like a bag of spanners. Further investigation has led to me being able to see a bit of play/movement in the flywheel. Probably a mm or two, which doesn't seem good. Get t he following:

1. Play in flywheel, this is movement when tight (torqued) on, so think this is reflected in the crank too.
2. Move it about a quarter turn a movement is less.
3. Move another quarter turn and no movement.

now thinking this is an engine stip at this stage, but wondering once stripped what I should be looking for? Any thoughts?

flyside roller bearing n clutchside ball bearing play ,theres usually a very small amount unless bearings are new/good ones , as play gets worse it starts eating fly side seals ,had it on my hack for a while coz i couldt get time to take it out of service ,it ate a seal every 3-4 months an i got replacing it down to bout half n hour tops .
if it gets real bad fly can contact ya stator which is expensive , H

Thanks Henri. I am on stator number two, there seems to have been some rubbing, so excessive movement is there already I think. Guess it's an engine split to replace bearings either side?

[henri]

definitely , did have a idea to mention a dry joint on ya stator n came on this morn to suggest it , only to find you'd sussed it n robbed me of a opportunity to look like a genuis, i dont get many chances for that ,ah well.
bearings n seals an whilst there kickstart rebound rubbers n check end play/shims on output shaft/loose gears , cruccy an if its a later efl with internal hub seal do that aswell. there all cheapish little things but if they go later would need cases apart again , a ballache , best done whilst ya can .

Haha....only took me buying two stoats to clock the dry solder...mare! Mind you the movement seems to have wrecked them a bit.

Was thinking of what else I could check and replace while in there...so thanks for the heads up.

Struggling....enjoy out scoot, stripped down but cannot get casings to split, there is movement, get a few mm's movement but cannot split completely, won't separate. Any suggestions on what could be holding it?

[henri]

turn the kickstart/shaft a bit ,quadrant catches on the cases ,an it will fall apart , honest/promise , an a bit of heat on the lower locating dowel never hurts , H

[Stovie]

Turned out the bearing had collsed and caused the issue getting the casings split. Took some 'persuading' to seperate, but all bearings and seals done now and scooter back together.

no knocking noises, sound great moving by hand, good compression....but no bleedin spark! Man just stuck again...unless I trashed stator before sorting issue.

Is there a way to test and confirm a stator is working, either in or out of the scooter?

[vespasco]

Yes there is a way

Multimeter (1 - 100Ohms) between ;

The red and white should read 110ऊँ's +/- 5. This is the one you can check if you have no spark.

Also, the green and white wires coming of the stator should read 500ऊँs +/- 20

Thanks Ace. eventually had to swap stator even though readings were looking decent. has started now with borrowed stator but running like dog. Mentioned in another thread...but barely got 10MPH at full throttle.
