So I ordered them 16/50 gears from Scrappy as per Millsc's advice, but I've been thinking this through and I'm confused as to how I get them pressed. I know the basic procedure that I take my gears off, then I take the parts to the press shop and they press my old gear off then my new gear on the shaft. But... How do I do that when my only vehicle is a scooter? Is my only option to first take my scooter to the shop parking lot, disassemble my gear box, then take the gears and shaft inside, have them press it, then put my scooter back together in the parking lot? It sounds unrealistic, but I guess I'm up to the task...  I should've thought this through before ordering them... They might come in the mail today with my brakes.  |

Are you sure they do need to be pressed on ? some don't.If you have a bench vise, you may be able to use that as a press

[replyingto=hank]hank[/replyingto]There's the tiniest chance that I can ask one of my mother's friends, but they cost as much as a taxi, and all my friends with cars are at college a few cities away. I guess taking the bus could be an option if I could figure out the route and such, but I've never been to this machine shop so I barely even know where it is, I had planned on using GPS to find it. What if I buy the gear that needs the shaft on it so I have an extra one for them to press on? I've heard they come in supposed "racing quality"? 
Would you be able to tell me the name of this "gear thingy"? I'd be able to point and grunt to pick it out of a picture, but I don't know its name.  EDIT: Found it I think: "Transmission, Gear Box , Short Case, GY6 50cc, 139QMB" Thank you. |

Doesn't your mother have a CAR? Also taking it out is a piece of cake putting it back is not 1, 2,3 you will need a gasket and oil to put back into the tranny and make sure it is not leaking. If you have some money you can buy a little press from HARBOR FREIGHT. Look for COUPONS and it will be less money. www.harborfreight.com/1-2-half-ton-arbor-press-3551.htmlAlleyoop |

I have 4 sets of gears. When I ordered a new set I also order a stock counter shaft reduction gear. It cost me an extra $30 bucks though, but this way I don't have to press the gears off and on when I want to change them. All my sets are hoca gears and they were real tight going in. I have an 80 ton press at work and the press gauge was reading about 10 tons to get the stock gears apart.

Another way you can press the gears if want to save a little money and DIY:
What I did was "rent" a 3 way 2 ton (I believe it wasn't that large) gear puller from autozone/advance for about $30 to use and take it back for your money back.
Use the gear puller to take off the old and to put on the new gear
Use an impact wrench is a lot easier to press off/on. Or a socket wrench works too, just is a pain.
When you are done you can test ride it (after putting back together and filling the gear oil).
If you like the new change, take the gear puller back to the store and get your money back!
Though that harbor freight press is a better option if you want to spend the money. I'd say its worth it to buy that 1/2 ton press anyway, its sure to have many more uses.

I'm almost relieved that the gears didn't come in the mail today. The delivery estimate was today, but I guess I should be getting them monday. This gives me some time to figure out what to do... millsc; No problem finding a machine shop, or some auto store that can press them. The problem is that my one scooter is my only vehicle. The process seems easy enough... Thanks for the link. @alley, no one in my house has a car. My scooter is the only mode of transportation we have. Everyone we know with a car charges at least $10 to travel anywhere, and any friends of mine that I know with a car are down state in college. Buying my own press seems like a good option at this point. roy, that's what I'm talkin' about! If I buy an extra "countershaft gear" and have the gear put on that one, then I can safely ride home and then just install my extra countershaft gear thingy into my scooter. Brilliant! |

[replyingto=bwader]bwader[/replyingto]Good idea Bwader! I'll see what my options are and whether I should get the press or to "rent" a gear puller...

If you do order a new counter shaft reduction gear you will have a spare stock gear. So if you need to change them back, no pressing would be needed.

Are you sure they do need to be pressed on ? some don't.If you have a bench vise, you may be able to use that as a press  I'll try that. I've got ocd tendencies so I'll be obsessing over these gears all day until I get them in. First I'll try the DIY methods, using my bench vice and autozone gear pullers, and when those fail I'll pay one of my mother's friends to give me a ride to the damn machine shop. The gears are scheduled to come today, so I tried picking up my mail, put it on hold and everything, but they shipped my mail out anyway and now since it's on hold it's technically lost until they deliver it, hopefully in an hour. Been waiting to install these gears since 6a.m. now, can't wait to see the difference! |
