any tips for removing the front sprocket. Used liberal wd40, tried heating sprocket. Pry bar and poor quality puller how can I get it off it won't move and worried about banging it as don't want to damage gearbox . Stuck
Looks like the rusty washer may be your problem. I'd replace that anyway, so get that off however you can, even if it's destructive to the washer and the sprocket may come off easily
I used this when first got my 999. The only bolt that broke off was the only one I didn't soak in this overnight. Look at this on eBay SOUDAL DEGRIP ALL 400ML SPRAY PENETRATING OIL DISSOLVES RUST & CORROSION | eBay
Thanks for the replies, plusgas is ordered from link , was hoping to get it done over weekend so may see if i can find something local. Old Rider , that is the rust from the washer i have the washer off no problem. Are there any tools that people use the puller i have is just bending . Is this just a patience thing penetrating oil , leave , come back try again etc.. Any advice on tools , tips or tricks greatly received.
I've an idea there may be a slot in the splines that the splined washer sits in and then turns, so it locks the sprocket in place. If so, that washer is definitely the problem.
I have new sprocket whats the best way to do that , i have drill , angle grinder but access is tight . My worry is causing more damage . Everything is off , its free to come off , if you saw the force needed to get rear off and once cleaned and greased goes on and off by hand . I know its just corroded in situ. Ill wait a bit and go and consider the splitting option thanks for all the advice its appreciated.
Have you tried tapping the sprocket from the front at all?? Anything to loosen the grip of the rust - as long as it's not violent enough to damage the gearbox
I had exactly the same problem on a CB500. After several all day sessions using all types of penetrant, including home made stuff, and different pullers I gave up....... And attacked the sprocket with a dremel and a pack of cut off discs. Took me about 30 minutes to slice down enough to relieve the tension on the corrosion and pull the sprocket off. I tried heat from various sources as well, if you do that, try not to fry the shaft seal behind the sprocket
Got it thanks all , put it away for the night and to watch rugby . I'll try soak with plusgas and if that fails it's dremel time ! At least doing it myself it gets the liberal doses of Gladus grease so cross fingers will be easier next time. Cheers Chris
I recon 4 short bits of strong metal with a hole in each end. Bolt together to form a square behind the sprocket so it can't be pulled off. In 2 of the lengths have a bolt hole in the middle with a long bolt sticking through towards the outside of the bike. Then another length of metal with a hole in both ends. Hole in both ends goes through the bolts. Middle of this length gets pressed against the end of the spline. As you screw down the nuts, both bit by bit, it would pull the sprocket off. Probably.
As I know you have to tighten the puller's screw and then you have to knock (not too hard) the puller's screw with your hammer (otherwise it does not work). Then you try to tighten again the puller's screw and if it feels loosen it means that the sprocket is moving.
