You'll need an impact wrench to get the front pulley off so you can make sure the weights aren't jammed up in there and take the clutch off too cause belt chunks can get lodged in there as well. This thread will help you understand what's going on in there: www.scooterforumonline.com/index.php/topic,2815.0.html |

Hey, thanks for the link, but did you mean to link me to another thread? That one is on how to change oil. You'll need an impact wrench to get the front pulley off so you can make sure the weights aren't jammed up in there and take the clutch off too cause belt chunks can get lodged in there as well.

The variator and clutch are in the CVT, or transmission. The cover is the CVT cover. There should be no oil in the CVT, or near the variator and clutch. The Crank is inside the engine, and where oil circulates. If all you cracked was the CVT cover, your ok. Never try to force anything together, there are 3 shafts that had to match up to that case cover on the inside, and a couple little positioner type thingies to match up, a little jiggling is more in order, and it is annoyingly easy to shift the cick start gears and spring out of position on these 150's. I would think that oil is leeking from a gasket. It also looks pretty gnarley. You need to change the oil and gear oil, LOL, use that other link  Did you loosen any of the 8mm bolts inside the CVT? It almost looks like it's from the gear box gasket. Clean it up and watch that, may not be too bad to live with. Gasket for the gear box isn't too hard to replace though, that would be the easy one. The actual crank case would be a PITA, and you will be wanting to find another cover for the CVT, is that a long case, 10 bolts to hold the cover on, or a short case engine with 8 bolts to hold the cover on? Can you get a picture a bit farther back on the engine so we can see just where we're looking? |

Its a short case, I loosened the 8mm bolts on the cvt cover and 2 towards the back end of the cvt cover, but when i realized they didnt attach the cvt cover i tightened them back. Would I really need a new cover for that that little crack? I guess it wouldnt be good if any water got in there

You didn't do anything to the gear box then. Those 8mm bolts are inside behind the clutch. When you opened the CVT you may have noticed a little gasket flap down by the bottom of the clutch, that gasket is from the gear box. Is that where your leek is around that gasket? You can probably get away with using that cover. I'de probably try a patch with liquid metal. A lot of guys cut vent holes for cooling, I don't think it's a major issue if that one chunk falls off. They don't allways use all the screws if they open the cover up a lot either. LOL, it would just bug me. You don't need a gasket for the CVT cover either. The Arrow manual here is what you want to download for that 150, www.chinesescooterreference.com/manuals.htm |

yes, I believe that is where the leak is coming from. I am going to open it up today to check and I will try to use some of that JB weld stuff. But I wanna know where this damn leak is coming from. I am going to try to change the gear oil and the oil today...from the looks of it its never been changed.

I would believe that the oil has never been changed, LOL. 15-40 for the oil, and the gear oil is an 80 weight, look for a gear oil with a small pointed tip at the end, it's easier to put in. The gear oil you fill till it is coming back out the fill hole.
There is no way to check your oil level in the gears, I would try to replace the gasket there as soon as possible. ( order a set or get some liquid gasket )If it were a slow drip anywhere else, you could live with it and check your oil often, but the gears only hold a small amount of oil to start with. You access it through the CVT, like I said, behind the clutch. Look over that Arrow manual and it will show exactly what I am talking about. Not any harder to do than your belt change.

Looks like its coming from the crank...any tips on how to replace the seal? The belt wrapping around it must have ruined the seal

I've never had the pleasure of pulling apart the 150.  You need to get to the seal first but it looks like that either means pull that gear off the crank or split the case somewhere else and attack it from the other side. Not an easy job either way. I might be very wrong though. Hopefully someone with a 150 will tell you I'm wrong and it's an easy fix. |

That's not good. There's no gasket there to leek inside the CVT other than the gear box. Could be coming from that hex like thingy above the crank, or the oil seal for the crank behind the gear. Or you may have cracked something more you havn't seen yet. Yes you need to pull the gear to get to the seal, not sure if you'd have to remove the crank. Any tricks without a gear puller for that gear? I found one for $65. I have a short case /case if you find it's cracked, but again, need to pull the gear to remove the crank as I'm pretty sure it's got a bad bearing. PM if you want to discuss that case. Clean it up, find the sorce of the leak, and check the Arrow manual for what you have to get at, and let me know if you need the case. I'll get a picture if I can find where my kid took my camera  |

damn, i tried to rent a puller from autozone, but none of their pullers will fit behind the tiny gear. Someone also told me I have to split the case, but I should be able to get to it once I get that gear out right?

Is that for sure where the oil is coming from behind the gear? If so, then yes you will need to open the case, and pull the crank to get to the oil seal. ( I don't know where to get a replacement oil seal) You'll need to pull the engine. The Arrow manual, starting page 9.
This is what I was looking at for a puller, but argh, $69.
