I put some permatex ultra gray (same difference as your yamabond 3). this is not true. Yamabond, hondabond, kawabond, etc are made by a company called threebond as I understand it. Threebond 1104 & 1184 are supposed to be the same as yamabond 4. I've never liked permatex, and most of there silicone rtv isn't gas or oil safe, so it can leak and end up inside your motor as little balls of goop. |

Whew, I got the case back together today. I used yamabond number 4 as the seal, I can def see some inside the case is this ok? It's not a lot and I got any bigger pieces out already.
Is there a torque spec for the case bolts? I put mine in hand tight but then the crankshaft didn't want to spin. That's part of my next question is how easily is my crankshaft supposed to move. As it currently sits I can turn it with one hand on the cvt side.
It went together fairly smoothly, I had the large half with the crankshaft and bearings on it in my freezer overnight and then heated the small half at 300° for 30 min and put them together. I did have to use my rubber hammer a little bit, and not hard just tapping it along.
I got a buddy making me a blank for the oil pump hole tomorrow. I have made up my mind on that. I just want the best for my engine after all this work so I'm not gonna trust a 12 year old oil pump.
I got two of the 3 oil seals in, the little one on flywheel side and the inner most one on cvt side. Is there such a thing as pushing them in to far? I used a piece of pvc for each one to press them in with the help of my rubber hammer. I made sure they didn't look crooked or anything but since I have never done this before I'm just hoping I did it right and didn't push them in to far. The case has lips to hold them.
Last thing, HOW DO I POST PICS? I'm dying to show you guys what's going on but can't figure it.

32:1 is 4 oz per gallon right? Correct. I used yamabond number 4 as the seal, I can def see some inside the case is this ok? It's not a lot and I got any bigger pieces out already. That should be OK. Is there a torque spec for the case bolts? I put mine in hand tight but then the crankshaft didn't want to spin. That's part of my next question is how easily is my crankshaft supposed to move. As it currently sits I can turn it with one hand on the cvt side. 50-80kg-cm is what the TGB 2T manual says. That comes out to 3.6 to 5.8 ft-lbs. The crank should move pretty freely with hardly any effort. Take a look at it or get some feeler gauges in there and see if the crank is making contact with one side of the cases. If it is, you may need to move it over. The way I prefer is with a special puller, but you can put a piece of wood over one end and tap it over. If seals are installed, then it's normal that it takes some effort. I got two of the 3 oil seals in, the little one on flywheel side and the inner most one on cvt side. Is there such a thing as pushing them in to far? I used a piece of pvc for each one to press them in with the help of my rubber hammer. I made sure they didn't look crooked or anything but since I have never done this before I'm just hoping I did it right and didn't push them in to far. The case has lips to hold them. On some engines you can push them in so far that they fall out of the other side, so yes. I'm not familiar with the TGBs. You say your case has lips to hold the seals so I'm guessing you'll be OK. I usually try to get the top of the seal about level with the case or slightly recessed. Last thing, HOW DO I POST PICS? I'm dying to show you guys what's going on but can't figure it. |

Ok what are feeler guages? I'll check it out more when I get home. Hopefully I can tap it over without taking the case apart again. I really don't want to take it apart again but I will if I have to

Here is an example of feeler gauges: amzn.to/2uFC2khYou don't really need them. Most of the time you can just look at it and tell. |

 I have been looking at it I dunno if you can tell in the pic but it looks like it's not centered. Like it's to close to the cvt side. I have tried tapping it over some but I'm worried about hitting to much. I have the bolts out of the case, I can move the crank but it doesn't feel as easy as my limited experience says it should. Tell me more about this special puller. For now I'm gonna take it home and try heating the flywheel side with the heat gun and tapping the cvt side. Any tips are appreciated, if I need to take it apart again do I need to replace the bearings and seals again? |

Well it seems I may have averted that disaster  I heated the fly side and air duster what I could get to of the bearing and tapped the end of the crank a couple times. Made a world of difference. I can turn it with one hand now with the case bolts in which I could not do before. I'm gonna continue to build now. |

Looks dry in there. Did you oil the bearings as you were buttoning up the cases? If not, I'd atleast oil as much of the crank as you can and give it a couple more spins before you proceed. See if that helps. It's gonna get oil mixed with gas later. But it's always better to know it's on there now. If you don't put the cylinder on immediately just tape up the cases to prevent dust from getting in. Hope this helps.

I don't know if your planning on going to a BBK but if you do a 19mm might be a better idea. Treatland has a 19mm clone for $60 right now. |

Ok I just noticed that is a phbg, I thought I needed a phva for tgb.
Shit I didn't oil it up in there, I'll shoot some oil in and spin her around a bit later.
I'm gonna install cylinder and start reassembly today, I'll post pics of progress now that I can.

Just realized I have that split throttle cable, where one end went to carb and one end went to oil pump. Since I'm going premixdo I need to delete that throttle cable now or can it wait until I get the new carb? Now I need to decide which carburetor I'm going with. m.1977mopeds.com/item/3338393233This guy looks pretty promising but why does it have two of those hook ups for cables. The general consensus from what u guys told me is no matter what carb I get I'll need a new throttle cable. Which throttle cable do I need and where do I get it? As far as choke goes I'd like to get a manual choke option with cable so I can put the knob up on the cvt side. I also like the look of this one m.1977mopeds.com/item/3338393231Whatever I get I'd like to be able to use the stock air box. I will post some more pics of the original later. This carburetor thing is/has been kinda driving me crazy. |
