- Installing and removing a scooter crank
First off thanks for everyone’s patience. We are absolutely slammed with work and short staffed: so these videos have taken the backseat. We squeeze them in when time allows!
Today we go the basics on removing a crankshaft from your common 2 stroke scooter, and installing a new one. There are several different methods, and tools, but this is one way of doing it. Remember to always have clean surfaces. Don’t reuse old c clips either. DO NOT use a press to join the cases together; this is far too common, and damages the crankshaft. You can either sweat the bearings in, Or press them in: I tried to make this video as short as possible but it was pretty difficult with all the details. Thanks for watching and remember we’re your number one source for parts, tools and advice!

This is the video I needed. About to do a full build on a PreBug
Thanks for the video! It's tough navigating through the European teenagers and their installation videos and trying to figure what's correct and what isn't. haha A day late, as I actually installed my crank and cylinder yesterday, but looks like I followed the right procedures!
hahahhahahah
Hi, i use premix gas now and i put a plate over the hole where the oilpump use to be, i saw you had a rod going down as well but do you think a plate like i have will do the job, or will it affect the engine. Regards Andree.
I'm so glad I found you guys! I need an honest answer. I have a 1989 Yamaha Riva Jog CG50cc that ran awesome until recently my whole variator assembly on the crankshaft detonated and the back tire siezed. Shockingly my drive belt didn't rip and is still in perfect shape! But in the process the metal pieces chewed up chip marks on the splines of the crank where the variator sits. Should I do a total variator and crank rebuild or should I just junk it as a parts bike? I have a 1984 riva jog CE50cc 1st generation and a 2005 Honda Metropolitan that I'd rather mess with but let me know! Thanks 😅
dammmm yess an upload :D so nice dude and i just worked on my chrome gilera 50cc :D im making it ready for a examination at a rdw office in the netherlands because its not road legal yet and it needs to be verry original to be legal hahaha
Have fun!
I love the shop banter so much

My 4 stroke engine (SYM HD200) uses a paper gasket. I was considering putting a very thin coat of Hyolomar on the gasket. Thoughts?
Awesome video...now you need to show how to cut the cases (on the DIO engine please...hint hint) for a stroker setup!! Thanks for the video!! SSS rocks!! Aloha!
Great suggestion! We are thinking of building a Stroker this year if we get time.
Heat/dry ice bearing just dropped 1/3 down. Panicked. Pulled out.Tried 3x more.Same.Any suggestions. Fire and ice, great concept if Itd work for me.🕊❤🍩
Malossi crank + polini bearings. Thank you.
Please enter me for bug eyes.
Your not heating the cases up enough, or not evenly enough.
Hi, I change the crankcase in Honda X8R when connect to cases is good. The crankcase turn very freely, but when i take bolts and I'm gonna install them the crankcase it's hard to turn. I use the crank tool. I took of cases once again and i didnt watch any problem. I don't know what is fail. Can you help me?
I know this is super old but, is it normal to have free play with brand new bearings?
I follow you from iraq, you are wonderful
Thanks how's the scooter life out there?
How did you pull that oil plug out? I’m having trouble getting my billit oil plug oil my elite
Hey Nathan. What style are you trying to take out?
The Honda elite billit plug that you can screw a 12mm screw in middle. Plugs right in Honda elite
@@nastynatesscooters9896 they can be really tight if they’re in with a sealant. Try taking a bolt with a washer! Thread it half way in and get leverage to pry it out

I have the same problem with me 01 Honda Dio...where you guys located and you doing job for public
Whats with the nitrile gloves?
They’re gloves
problem is, with that tool you are forcing the inner and outer ring apart from eachother, and that is gonna create tiny indentations in the bearing, where the running surfaces of the balls are. my method of choice is to heat the bearings & freeze the crank, assemble the crankshaft, and THEN heat the block halves and then assemble the whole thing together. during the assembly I don't use any pulling tools, I quickly tighten all screws and then all it needs is one small longitudinal tap with a metal hammer to ease out the stress.
Yea everyone has a different method. I will say I have been doing this for over 8 years and have never once had any failures or issues. I also don’t like heating the bearings up red hot personally.
@@Scooterswapshop not red hot, but the perfect amount of heat is when water droplets bounce off the surface (I believe 180-200°C when that happens, it doesnt hurt material structure). tell me that it's unscientific, but have you ever seen an infrared thermometer that can read on shiny surfaces? ha...! everybody does it on their own practice, I even know people who assemble everything cold turkey, with pullers and presses.
New sub aloha from hawaii 82 mini stroker 🤙🤙
Where can i getthe wrist pin toolplease? Need an answer ASAP please, GOD BLESS YOU, this video is letting me help a scooter rider serving at church.
call the shop!
@@Scooterswapshop number please?
can you do a motor mount alignment on a scooter tutorial?
alignment? like how to put the bolts in?
Hi, i'm a fan of your work. Just wanna ask about some problem of my scoot coz it got stuck on the rain and my parking lot got flooded. Now good thing is the engine starts but the real wheel wont spin. I hope you can help with this one.
Could be 30 different things.
Currently in the process of rebuilding my Honda 4T 125cc Scooter so this video helps a lot. In regards to HondaBond, I've bought Three bond 1215 which I believe is the same thing... my worry is putting too much on and it breaking off inside the case and blocking oil passages. Does that happen with this stuff or is that mainly the RTV sealant? My first rebuild so want to do everything right the first time. Thank you for the video!
I don't know that brand but honda bond done too much can be bad yes
@@Scooterswapshop I had a change of heart... got mixed reviews about ThreeBond 1215 which is meant to be a HondaBond 4 equivalent. Just to be on the safe side, I've just ordered HondaBond HT... it's a bit pricier in the UK. I'll stick the threebond on ebay get my money back!
Why did you use Motion Pro on one case half,and Tusk on the other?
Because those are the brands I keep in the shop for personal use. Doesn’t matter which brand is used
@@Scooterswapshop Do you have a preference?
Can I ask you the best way to clean the out side case . I do not want to take the whole thing apart . And Thanks
degreaser
why is the piston covered with a towel?
So it doesn’t get damaged
Do I have to take the whole motor off &’ apart just to change my crankshaft??
Yes it’s in the middle of your motor
Wow you made it looks so easy what size belt you use on that dio
call the shop for your fitment
Hi, my magneto will not come of! (is as if it is stuck). I have removed the screws. Do you have any tips?
heat
This Chanel should be call HONDABOND!
ReyAleja Hondabond is life
What case splitter should I get to split my Honda elite af16?
tools all on our website
Nice vid! Quick question when the rod becomes loose and has play is the repair procedure the same as far as pulling it back into spec with a tool?
You have to replace the crank
@@Scooterswapshop thanks had a feeling that's what it was gonna be 😅
I wish you would have said if it was left hand thread on all, or on the stator side, vice versa. I get there not all the same but still just advice.
cant cover every single bike and piece sorry
22:00 Y’all sell that tool? Or what size is that?
What grease do u use on ur crank oil seals and do u lube bearing with grease or leave them dry as they come only asking as 1st time builder
We use 2 stroke oil or Lucas assembly oil
I use 2 stroke as it burns off
i have a question if the crankshaft moves up and down where it hold the variator does that mean i have the replace the crankshaft or the bearings?
means you have issues with something
Should only be the bearings but check for play in the rod :)
Havent seen any post from SSS.. was wondering what yall were up to. Great video
850 ARE thanks! Super slammed on top of short staffed
Scooterswapshop i bet.. i know bicycles and scooters and anything 125cc and under are selling out everywhere
Is it possible to put Yamaha tmax 500 engine into Yamaha versity 300 frame?
anything is possible
What size bearings go into the crankcase? Qmb139 50cc
should be on the site or call the shop Paul can source them
Maybe it is easier to take the brake caliper off instead of disconnect the brake line. If you habe brake disck in the rear. Otherwise you will need to get new brake fluid and you will need to bleed the system.
many ways of doing things.
Hi guys, i am rebuilding my sons Aprilia SR50R. I have split the cases and installed new crank bearings. Put the crank it one side and it was spinning fine. Joined the 2 cases and the crank does spin but it takes quite an effort to spin it. I didnt use a crank puller. just hot and cold method. thoughts? some people are saying the crank is not centred and i need to tap the crank ends with a rubber hammer?any help appreciated.thanks
Good chance either the bearing didn’t go into the case all the way. Or the crank didn’t get fully seated into each bearing. This is where the hot and cold method can fall short, and the puller comes in handy
@@Scooterswapshop Thanks for the reply. its a learning curve eh? :) after a lot of thought and staring at the engine. i decided that the crank was very close to being in the right place .i know that hitting the crank ends is not good practise but gave the stator side a whack with a hammer and a bit of wood in between and it freed the crank right away :) hope its going to be ok :)
Hella good vids 🔥🔥 But i have a gilera runner 50cc and i have a realy tight budget so if you have some tips for mods or other stuff i would appreciate it. I have looked on a technigas rsll or next r, do i need to do jeting tune or am i good. But i feel a Huge bog and the rpm is rising But i aint moving and after a while i start picking up speed, is it the clutch sliping? But i cant look at the clutch cuz i dont have the pul thingy. But if u recomend smaller mods or cheap things that will make it morse complete and Nice i would be so greatfull. Om not looking fore huge preformance more like clean and btw im 13yo so thats why my budget is shit and tools😂btw love ur chanel and keep it up👍🏻
thanks!
What sup fam, if i instal the bearing uneven and i whack it out and put it back even, is the bearing stil good to use?
you whacking it in will likely ruin it... if you have you likely messed the cases up you have to press it in using a press!
@@Scooterswapshop I don’t have a press, i thing im gonna use the hot cold method
What is the exact name of the cranktool the blue one.
go to our page and search Motion pro
Do you lubricate the crank bearings?
wont hurt to use assembly lube
I need your help with my zuma same problem
You fix it?
Can you confirm if the crank seal goes or failing can it or would make the bike switch off at high speed just like a power cut as if someone’s turn the kills off subscribe btw good vid
If you have a failed seal you will have an air leak. So yes it can cause your engine to shut off
@@Scooterswapshop thanks for the reply yes I’ve check seals and they seem be okey but I do think the seals or crank bearing have gone
Hi what engine casing sealant did you use?
Honda bond!!!! www.scooterswapshop.com/products/hondabondht?_pos=1&_sid=899011e13&_ss=r
Thanks man!
thanks for the video brother !
No problem 👍
Good work just talk more thanks
How much for the spree. Ship it to me.
My cousin has two sprees... what is your offer?
We aren't selling
Whole, Look at this fukn guy🤣🤣😵🤣
ha
Yoo what sup. Any honda dio for sale. Thanks. Nice vid
Not at the moment but we’re goin to be raffling one shortly
I'd buy the hell outta your bent up scooter my dude lol. How much you asking?
Ill trade you some other scooter / scooter parts for it ?
@@thelegion3682 got rid of it forever ago. It was fun for sure
@@Scooterswapshop oh I heard that man. Thanks anyway. Well I appreciate your helpful videos and I definitely look forward to seeing your future uploads. I've ran into a little problem on a 2005 Zuma 50 I bought off FB marketplace recently. I noticed a slight low speed wobble in the rear wheel so I got back there to check it out and sure enough the entire back wheel is offset by about two inches and the lug nut that secures the wheel on the splines is just maybe two threads on the output shaft. I'm not sure how to tell whether or not it's the wrong wheel altogether or what it is. I bet you wouldn't happen to have any idea whether or not a wheel off of a 2011 Zuma 50 would fit the splines and everything on my 05 Zuma 50 would you? Im trying my best to purchase the whole thing together wheel and tire and tube if it calls for an inner tube that is. Thanks man and again I really appreciate all of your videos they're tremendous help to so many people. Have a good night.
Hey Jack all 02-11 2 stroke zuma wheels are the same rear wheel fitment
@@Scooterswapshop thank you more than you know. I have tried my best to figure that out because I need to buy a complete wheel and tire but I couldn't find the one that was for my specific year model so I really appreciate your help my friend. I will finally be able to buy one now because I seen several on eBay for a few years newer model .
🥰♥️♥️♥️♥️👍👍👍
