Very good video. Straight to the point. The first time I pulled the gear, the tool confused me but once you do it you'll understand. I wouldn't use a pair of needle-nose pliers or vise grips. A couple of channel locks works good too. One to hold the gear (with rag) and one to gab the tool. Other tools... an adjustable wrench and vise can be helpful too. What ever works best for you.
Had my first engine for years and never noticed that my sproket would kinda spin off when I dropped the clutch. I swapped the engine for a whole till that one blew up in the top end from something that got into the cylinder. Anyway my point is I was just going to bed tonight and realized that these probably have a key and I had stripped mine 😂
My teeth wore out quick. I'm gonna order one but this time heat treat & temper it. Like I did my rear sprocket which has same mileage as front sprocket but has no major wear yet. All you need is propane torch or Mapp gas & simple heat treat/temper instructions. They bother to heat treat them in China in order to keep manufacturing down + u end up buying another one sooner. Just thought 💭 It'd be a good idea to heat treat the puller tool also.
Thank you so much I was trying to figure out how to get the chain off without depressing the clutch as I found this motorized cruiser in the trash & fixing has been fun
Its considerably harder to pull the clutch side drive gear as those threads are like butter. Its super important to get that tool threaded as far in as possible; I know from the experience of stripping it out and its so not fun I almost junked the whole Damn thing out of frustration.
I can’t get my gear off. I threaded the tool all the way on and then threaded the bolt all the way in as far as it can go but the gear looks exactly the same like it hasn’t moved at all and the gear will not pull of the engine. I don’t know what’s still keeping it on
Nice material on your channel I was looking at it because you made a comment on my I have a set up very similar that your with a 80cc port polish ,jack shaft is on my treck mountain bike ,Hart yo fit I did cut and costom made new attachments point
Sorry for the delayed reply. There is only one ball bearing. It suposed to come out. Just insert it back in there and then put the bucking bar back in with some fresh grease.
Question has any one tried adding to the gear to extend it out. It would help the chain to clear the back tire. I've tried to add a thick washer underneath it but it didn't work to hold. I'll have another idea. Cut off the back of a gear. Flat grind it to a thickness of about 3/16 . Then welding it to a new gear with the key slots inline. Or maybe a different size shaft. ? Just an idea, anyway if any one has a good idea let me know.
If u have a coaster brake and want to keep it trying taking the axle out and shift the the locking nutrients assembly on the train Side s qtr inch to the left. I had to also grind the coaster arm so the tag sprocket bolts wouldn't hit it
Jelle Zwart did you end up doing this? I want to do the same because my chain is rubbing the tire and I want to move the front sprocket out a little too see if it moves the chain out of the way
Yelsok Nairb no I haven’t done this. I thought it was best not to mess with the internals. I got thinner tires, which solved the problem for me. Hope this helped you!
@@jellezwart9155 thanks. I did the same. Was hoping to go back to wider tires but thinking more about it I remember if the chain is angled it will pop off the back sprocket easily so I'll probably stick with thinner tires like you.
Saved my life dude! I really only looked it up to see if it was threaded counter-clockwise or not but your info is all good, thanks! Btw, how does that bolt on reed intake work out compared to stock?
the. a bolt on reed is must have for optimal performance and more importantly prevents blowback of fuel and gasses. nothing worse than having a filter saturated with fuel oil mixture which also inhibits proper intake of air.
Master Blaster. Only take the clutch or drive gear out in whatever order you want if need be. Secondly, use a wrench to thread the removal tool as far as it will go. At least 5 turns in.
I just removed the clutch shaft on 2 engines, and on one of them, the treads inside the sprocket weren't cut right. I kept screwing it in, and it never screwed in flat. It was always off to one side, and I thought I was cross- threading. I wasn't. I had one engine (the good one, for the customer's bike) and the bad one, off of the customer's bike. Good one had a bent clutch shaft. (I got that engine second-hand, so I don't know what happened.) Bad engine, had a decent clutch shaft. After figuring the sprocket had S***TY threads cut, it came right off. After getting that bike finished, I did NOT want to part with it. Customer was a former employee, of my former boss, and had the bike, wanting me to fix it. Some @$$HAT had mounted an engine on a Chinese "Schwinn" girls bike. One motor mount, with a single bolt in it, other mount had 2 bolts broken off. The rear sprocket, something "welded" together. To quote something I heard on Roadkill; Looks like it was welded by Ray Charles! With his FEET! steve
@@ericscott8230 One of the local bike shops, also does gas and electric powered bikes. I took the engine in, and asked how much they'd charge to pull that sprocket $15, but we have the puller for $6. Guess how much I paid. (They get engine kits, and some of them have tools with them, so they sell the tools.) steve

Thanks this helped a lot. I never would have been able to figure out how that removal tool worked.
I'm new to the motorized bicycle and I'm finding it very interesting especially working on these small engines you were very informative good job.

Oh, impact driver! Pulled all 4 loose.
No wedging stuff in the way. I've
got a cheap $40 HF electric impact.

What if I don't have the tool?
What occurs with the its electricity when the magnet is incorrectly installed?
I doubt it affects much if anything is literally just a magnetic coil
i cant undo the big bolt and ive already snapped the nut wedged in between 'help me?
I lost the ball bearing can I replace it with 8mm ball bearing ?
Thank you
Thank you!!!
Theyre called vise grips I never heard them called a combination wrench.
My bad. Let me clarify. When I said combination wrench, I was merely referring to using one without it actually being present in the video.
Very well explained, easy to follow along
ive got the sprocket on but the nit wont go on
how do u get it off without this tool I dont have the time or money to get one
Do I have to pull it off to put the chain on
the tool wont thread into sprocket. threads are buggered i guess, any other ways to pull this?
I only know to use that tool. unfortunately the tools ate cheaply made. you may want to buy another and try again.
after removing sprocket my bucking bar is too long and bucking bar cover dont fit
how do i put it back on
I pulled the bucking bar to grease it, and some of the ball bearings came out. Could you help me on putting them back in place. Thank you.
Sorry for the delayed reply. There is only one ball bearing. It suposed to come out. Just insert it back in there and then put the bucking bar back in with some fresh grease.
Where I can Buy the new Sprocket + Remover?

I like the way how you do it look easy I like your video
Where do I get the tool I lost mine
I bought the sprocket removal tool and its less than a millimetre to big. What should I do?
I need your help. Could you tell me what the tool is called and what size it is and where can I buy it to remove 10 tooth clutch drive gear

Have a question my whole drive sproket moves in and out what dose that mean? Is there any way to fix
Does anyone know if there's a replacement sprockets for these that use #35 chain ?

Hello,
Can you use a couple of washers to get the sprocket a little to the outside?
Thanks
yes but you may want to leave it as is unless absolutely necessary.
Jelle Zwart did you end up doing this? I want to do the same because my chain is rubbing the tire and I want to move the front sprocket out a little too see if it moves the chain out of the way

do you supposed to take out the clutch and drive gear first. my sprocket will not come off this way. the removal tool keeps popping out? pls help.
Master Blaster. Only take the clutch or drive gear out in whatever order you want if need be. Secondly, use a wrench to thread the removal tool as far as it will go. At least 5 turns in.
how do you know if its bad?? any help will be good. i cant get it to ingage.
Master Blaster, if what's bad? Get what to engage? Please elaborate.
What can I use if I lost that little piece?
If your referring to the woodruff key, I would say there is no substitute. You can find those at Lowe's or HD or a specialty hardware store.
I snapped i peice of my engine block doing this
What piece?
