I'm asking for suggestion for what kind of tool to buy to pull the gear on the variator side.
I need to split the case, remove the damaged crankshaft, and then decide if the case is still good enough for a rebuild.
I would prefer an affordable Harbor Junk tool as I don't know when I may use it again.
The last thing I want to do is to have to custom-weld a tool as shown on the Youtube link below.
Thank you,

Any suggestions on what tools to use to pull the Timing Gear of GY6 150cc? I'm trying the 2-1/4" Bearing Splitter (from EBay) and Puller Set (from Harbor Freight Tools #93980) method. (see scootdawg.proboards.com/thread/40748/leaking-cracked-gy6-crankcase?page=1 3/4 down the page). I'm having a hard-time fitting the Bearing Splitter in it, before tightening it, and then using the Puller Set. Has anybody bought through AliExpress? Is it safe if we use PayPal? They have great prices directly from their vendors, but I don't know how safe the purchasing transactions are. Thanks |

I'm surprised that a lot of the part suppliers don't sell an item to remove that gear. It'd be nice if they did, but maybe there is some reason that they don't...or maybe some scooter site does.... hmmm..
This topic comes up several times a year, and the answer is usually-- rig whatever you can, try a certain puller..etc. which is fine. I guess whatever works...

This is an old Pitman arm puller that I had. Only slight modifications were required but it pulls the gear in 30 seconds Attachments:

I already purchased a $13 bearing splitter (small, 2-1/4") from ebay. That, along with my existing wheel puller set from Harbor Freight (http://www.harborfreight.com/46-piece-bolt-puller-set-37824.html), I'm going to try to yank this thing. If I can't, I'm going to bite the bullet and try the EBay of China called AliExpress, for a tool that is specific in pulling it out, kind of like the Pitman Arm Puller mentioned above. They have GY6 specialized tools such as this Timing Gear Tool. Apparently $20 + free-ship. www.aliexpress.com/item/Timing-Gear-Tool-For-WJ-125-Motorcycle-Repair-Tools-AT-G236-Free-Shipping/370890172.htmlJust like in the early days of EBay, gotta try once to see if we can trust it. They have other tools specific to GY6 that seem inexpensive and very handy when you need them: 1. Manual Variator Face Holder, so you can remove that Variator Nut, $10.12 + free-ship www.aliexpress.com/item/GY6-Scooter-Variator-Remover-Puller-Tool-Scooter-Parts-AT-G204-Free-Shipping/332348117.html2. Bearing Puller RemoVer Set, $33 + free-ship www.aliexpress.com/item/Bearing-Puller-Remover-For-Scooter-Motorcycyle-ATV-Yamaha-Honda-Suzuki-Automobile-Bearing-take-off-Repair-Tools/710451548.html |

I have bought from aliexpress with no issues. I used the bearing splitter and pulled method when I did mine. Can't fully tighten the splitter, not enough room. Just snug it up, put some tension on the puller then wack it with a hammer and it should pop right off. To put it back on use a piece of pipe and a couple washers then tighten the nut on the crank to pull it on.
