Front Sprocket Stuck On Driveshaft

z0sum · February 19th, 2017, 09:54 PM

I've tried pulling the thing as hard as I could and it just won't budge. Seems really in there. I tried spraying some WD40, nothing. I've got the bolt and washer off and it's just really stuck in there. Wasn't expecting that, anyone got any suggestions on how to get it out?

MLR · February 19th, 2017, 10:19 PM

Light tap with hammer.

dcj13 · February 19th, 2017, 10:19 PM

Both bolts and the three-holed diamond shaped bracket thingie have been removed?

Tried this. It didn't seem to help. I've also read that it could damage the shaft so I stopped.

There's only one bolt and a washer holding the front countershaft sprocket to my knowledge and those have been removed. I ended up ripping the front part of that rubber cover thing in my attempt to pull it off. It's really stuck on there.

The picture above that motofool has posted is a gear or pulley puller it is the way. Most major parts houses i.e AutoZone, advance etc. Will allow you to barrow this for next to nothing. And they give your deposit back up in return of the tool.. also do not use wd-40 around your chain or hearing. That stuff is more solvent than lubricant. Their are other penetrating oils that aren't harsh. I think on blaster is one of them and In my opinion I feel it works better. If that down at work theirs always the good ol Stick a rag in the gas tank and light it technique. That will defiantly get it loose

thats a heat gun

csmith12 · February 20th, 2017, 01:53 PM

1 2x4 to stick between the wheel spokes and swingarm
1 24'' or greater breaker bar with the proper size socket
1 helper to hold the bike steady

Nut comes off like melted butter

The nut is not the problem, that's been taken off along with the washer. The problem is that it's still stuck even after. There's nothing holding it on, it's just stuck on there from what seems to be... rust?

cbinker · February 20th, 2017, 05:18 PM

penetrating oil and a light tap from a mallet.

Ah.... Cool

Heat will mostly help in breaking down the corrosion on the threads or the existence of thread lock. Any red or blue residue on the shaft? That alone could explain your troubles.

PB blaster overnight, spray a few times before going to bed. When your read in the AM, use the same socket that you used to remove the large nut, place over shaft and "gently persuade"

the sprocket loose on the shafter with a hammer.

AoA J0ker · February 20th, 2017, 06:02 PM

Dude go get a puller. No offense brethren commentators but I do this for a living. There is no lock-tire on the output shaft ( hear in the middle of your chain sprocket.) When you get a puller be sure to get the socket driven kind. The T Handel sux

Where could I get one?

dcj13 · February 20th, 2017, 08:11 PM

Harbor Freight.

csmith12 · February 20th, 2017, 08:11 PM

Autozone, home depot or anyplace else that rents tools should have a claw puller.

And... people do stupid crap to bikes, unless your bike was purchased new, then there could be ANYTHING holding your front sprocket on. In fact... MY own bike has it WELDED to the shaft.

Any chance you can post a pic?

AoA J0ker · February 20th, 2017, 08:29 PM

Most major auto part stores have loan a tool crap that you can barrow. Be like hey man I need something to grab a gear and pull it off and stuff. And that dude ( or dudete) is gonna be like " oh right how bout this pully puller?" And your gonna be like " RAD but hey man this kind sucks, cuz it has the T Handel." And who ever the he'll your talking to is gonna be like " that's all we got yo." And........ do you understand where this is going. Do I really need to exaggerate my point any further. Good day

So will the T handle one still work?

Dang... that thang is more froze up harder than woodpecker lips.

z0sum · February 21st, 2017, 05:57 PM

I don't have a heat gun... how important is the heat part?

I called up AutoZone, basically their loan system is you buy the tool and return it....

Thing is, the tool seems like it might have a problem. What I found was sort of this.

http://www.sears.com/craftsman-2-3-j...2&blockType=G2

It looks like there's that screw in the middle that requires a flat surface to push on, where the shaft would be. The shaft has a hole, wouldn't that screw just go through the hole and have nothing to push on?

csmith12 · February 21st, 2017, 06:10 PM

Is there an ART's rental near you? They offer true rental vs buy and repay later. The real deal is if you can get it rented and returned quick enough the hold on your card is only 24 hours and then canceled out.

Actually, the puller you linked is one of the better ones. NOT a t-handle, which means you can put a socket on it and put as much force as your socket will allow.

I know you are young and new to things. I applaud you for going the extra mile to ensure your start is a success. This is but one step of many.

Keep it up and you will have a great riding career!

pantera · February 21st, 2017, 06:14 PM

Have you tried just tapping all around the sprocket?It should loosen right up.

csmith12 · February 21st, 2017, 06:14 PM

I forgot to answer your direct question, Is the heat required, not really... it kinda falls in the column of work smarter not harder. You might as well get used to it now out of the gate, your gunna have to trust your gut on matters such as these. So goes the life of riding.

Get a puller and combine your information to make it as easy as possible. ie... that is gunna need some soaking in penetrating oil to break lose without much fuss.

Yea man it's really on there. I don't think just banging it off will work. It's ridiculous how stuck on there this thing is, even after removing a bolt that holds it... it doesn't seem like it even needed the bolt.

Thanks, yea, I'm sort of new to all this. But this forum and ones like it are very helpful.

Okay but the center shaft issue. Are you seeing how when you turn that socket, there has to be something for it to push on, and the drive shaft seems like it's hollow, there's a hole in the middle of the shaft where that screw thing wants to push down. I don't mind the AutoZone "loan" thing as long as the tool will do the job.

csmith12 · February 21st, 2017, 07:40 PM

If you can get what you linked from autozone, then there shouldn't be much issue as "you can get a good bite on the sprocket." This is one of those cases where an ounce of prevention is worth a pound of cure. Take you time, trust what you see, feel and go from there.

Honestly.... we can only do so much via the inets... But they, I don't have the big head. Maybe someone sees something that I don't.

Either way, if there is a friend or someone that can help you, don't hesitate to pull that trigger. Worse case, you seem silly, best case you got one less worry and made a friend along the way.

Edit: Crap... going back to one of my previous posts... you will need a short 2x4 to put between the wheel spokes and swingarm. Take your time and figure it out so you don't cause damage. It's really a piece of cake. You got the nut off already, the hard part is already done. If you get a puller, this is far less of a requirement.

jrshooter · February 21st, 2017, 09:59 PM

if the screw goes in the hole, just cover the hole with something, a piece of metal, or maybe a socket, something for it to push against.

z0sum · February 21st, 2017, 10:05 PM

Got it off! Thanks for all the help, guys. What worked was the puller I got from AutoZone. I let the screw just go in the hole hoping it'd eventually hit something, it did and it pulled the sprocket off.

Feedback from this side of the planet:

The nut for the front sprocket for the N250, N300, N650, N1000, Z1000 and ZX10 are all difficult to remove. It's like they're spot welded on. The dealer's shop even asked me not to bring it to them when I want to change the front sprocket.

The best way to remove it manually is to use a 6 foot lever. A buddy uses a Pneumatic impact gun with 800lbs.of breakaway torque. He says it works like a charm.

rgx107 · February 22nd, 2017, 09:22 AM

Remember to keep the washer, you need it for the reinstall. Also strange thickness of the sprocket, on mine the washer is just flush with the end of the splines. Entirely different generation though.

Clean the shaft and its splines very well with a wire brush before installing the new sprocket.
For tightening the nut, you can use the same idea given by Chris in post #9 above.
