scooter revs but wont move  By  rickwagner (Read 19,553 times)

Ok, so I put my battery tender on it all night to charge the battery. I just made a new vid ill post here as well. So what I noticed yesterday was that there is a bushing for the bendix that was missing. I made one out of a 5/16 socket. Fits inside the bushing hole and fits around the bendix shaft. I put that in and it works to a degree. Here in the video you can hear the bendix disengaging while I'm in the middle of cranking the engine. At the beginning of the video you can hear the engine fire up and start to rev, but as I'm revving it up you can hear the belts begin to squeak and then it dies. After that its mostly just alot of cranking. But right now I think I may have two problems that just happened to both start around the same time. Probably one is the bushing/bendix. And the other is whatever is causing that belt to squeak. Right now I cannot get it to stay starting long enough to mark the variator. Whatever is causing that belt to squeak like that is like a vampire sucking the power right out of the engine causing it to stall out. That is exactly the same noise it made when it stopped working and I managed to get the engine to start, and every time after that I was able to get it to start since saturday it has made the same squeaking noise and wouldnt move an inch, it would kind of move forward a half an inch but then just settle back, feeling like it wanted to engage but would not.

The clutch....should it just open and close? I grabbed the pulley behind the clutch and pulled it open, but it wouldnt close by itself. I had to try to start the enging to get it to spring back closed...that normal?

On this 50s it makes it difficult to see the cvt working because of the bendix and if you take the cover off you cannot kick start them. If you jack up the rear by the axle so the wheels are off the ground and are able to spin that will show if the clutch is already engaged when trying to start it they will turn.

You are going to have to byte the bullet and take the Variator off and check that and the clutch as well. If it does not move when the motor is working it has to be the Variator, Clutch or inside the tranny or somthing in the axles or differential. So something is binding and not allowing the motor to turn over freely to start.

Ok since you have nothing to loose do this take the belt off and grab the Variator and see if it moves forward it should slide really easy. Then you can grab the outside Fan plate and turn it and see if you can feel anything that is binding on the crank.

Ok, update time. Been away all week at my supervisor's house so I could make it to work. So I did a little work today. Bought the impact wrench and took the clutch off first and tried to crank the beast up. Still very hard to start. Now I took the flywheel and variator off and the variator looked good, didn't seem like there was any damage to the crank shaft or the transmission shaft. However, after trying to crank the thing up, what I notice is that the starter bendix is ALWAYS engaged AFTER I have tried to start the thing up. As if it is staying out and binding up the engine. Unless my socket bushing is binding it up, but I doubt it because even without it in it will still be hard to start. Here is a video I took, let me know what you think allyoop.

Ok, new update. Got the bendix in today. Tried to adjust the throttle screw a little bit to make it easier to start. Was able to get it to start, altho it seems rather hard to get started. After it started, the engine seems to have a knock in it, and a squeak. It will idle for about 30 seconds if I can get it to start, as soon as I try to throttle up, it dies. So it either has to be the piston is F.U.B.A.R again, or maybe the shaft for the fan/flywheel is screwed. I have the tender on it so I can charge up the battery and try to get a video so I can show you what's going on. Probably another update tommorow.
