Anyone know how to get the damn flywheel off the GST, it is driving me crazy

Pop the clutch shoes out, then take the large nut off using the wheel nut box wrench.
The flywheel is on a taper, so you will have to get a large flat screwdriver behind it and twist.

Don't do what I first did and spend 30 mins rotating it before realising it is not unscrewing!!![&:][&:][&:]

Your Hand Book will show this assembly in and exploded diagram.

take the clutch bell off then the clutch shoes and then take a pair of challelocks and grab the flywheel and take a 8 or 10mm (i think its that size)wrench and take that nut off and then the flywheel shoudl just pop off or you might have to pri it off

let me know if it worked for you

The nut that holds the clutch nut on a Genesis is actually a 17 or 19mm. I can't remember off the top of my head. And yes I am sure it's a 17mm or 19mm. It's a huge clutch, what do you expect?? LOL

10mm is the standard size clutch nut for most 8th scales, but not the GST/Genesis/Nemesis. hahaha

Hey Rob, Yeah, What s5lin Said!!

offroad, if prying makes you nervous about scratching, galling or damaging your bearings you could use a pen/micro torch to heat up around the shaft on the flywheel and as the aluminum expands it should release the brass taper bushing and just "let go" of it. Be sure to use gloves or something so you dont burn your hands..


Oh BTW dont forget to be sure the engine has set for awhile to let the fuel evaporate, and be sure thetre is no fuel in the carb



Be patient and most of all have fun!!!!

simion its really that big.......i dont remeber it being that big on my genny.....oh well mabey its different

NO you will not damage anything if you do it right ive been doing it this way for 5 years (if it doesnt come off by hand)and have no problem

There is no way it should come off by hand, unless youe either pry it or heat it.

I had everything off already except the flywheel itself. But I finally got it off. I took 2 flat head screwdrivers put one on each side and pryed it off. When it finally came off it shot across the room like a bullet. That damn thing was really on there lol

well headrush has done it again???
given advice where he has no "experience" in working in the Nitro relm......
if he had had some experience, he would have recommended using a
"Battery terminal Puller"there small can fit in a tool box and Inexpensive....most auto parts stores will carry these....for under 5 bucks.........
usinga pair of "Screwdrivers" yes you can take it off but there is a "Risk" in "Cracking" the block.
as i "Have Seen it Happen"......not something i would advise....it can be done though....

yup thats right ROBs done it again gaving advice that works for him[X(]

yea you guys should do blades idea after he knows all the cheap ways since hes cheap

but somtimes they do come off by hand

Good call Blade!! The battery terminal puller works fantanstic!! I just took my nx76 out just to check this out and reset my gear mesh..It works flawlessly!!

Headrash...I would be careful about advising people to do dangerous things...The flywheel flying across the room like a bullet is a common occurance using that method(prying screw drivers). Now if you had advised him to put an old wash cloth over it(to control the flight of the flywheel) as he was prying, it would have been more sound advice. Not trying to be rude, I just kept reading this and it bugged me that this guy could have easily put his eye out when that flywheel shot up and dented his grill and one of those studs on the flywheel hit his eye. I thought long and hard how to tell you that, but I guess direct won out. Dont get me wrong..that flywheel does not always "POP" off like that but why risk it when there are better ways to do it. Being 16 does make you special in all your wisdom, just enough to get you into trouble. I do hope there are no hard feelings but I would be remiss, knowing that danger and not sharing with you, since it happened to me many years ago when I was working on a weed wacker and it "POPPED" loose and chipped my front tooth. Wanna see a picture of my chipped tooth?

I dont even know you so I am NOT trying to flame you, just trying help by sharing my experiences and keep the hobby safe.


BTW,,Expect to be corrected when you give advise like that...

Good call Blade & TRD,

The other benefit in using a puller, when this kind of tight fit is encountered, is that there is no risk of damaging your bearings.
This is another real risk, if using the 2 screwdriver method, due to all the pressure being applied to the block & in turn the bearings, via the crank!

HeadRush ROB.21, Please take this as constructive & not destructive critisim!

Happy Nitro'n,

Every good point, I didn't think of that.

How are you guys getting the nut off? With the four dowl pins for the clutch shoes there I cant get any tool to fit on the nut. BTW it is 17mm.

Nevermind, I had to grind down a socket to fit between the dowl pins. There is no way the 17mm socket on the glow plug wrench is fitting between them. Not sure why they even have it there.

our cross wrench fits pretty good... glad to hear your problem is solved!
Have a nice day,
