Maybe it's been Loktited? It should only be 40ftlbs.ok guys i got my hands on an impact wrench and it still wouldnt break free
Are you reading "impact wrench" as "rattle gun"?the countershaft bolts usually also have a type of lock washer on them too...i dont think ur stupid enough to miss that but just a thought...also yes the chain should always be left on when taking that off...there is a book called 101 sportbike performance projects that has a lot of useful tips for the new motorcycle mechanic...i suggest u grab one...it will help you with any project you will do on any sportbike...get one and u wont regret it...Make sure the impact wrench is set right too because they have torque limiting settings on them which will prevent getting off a tight bolt...I really cant believe a impact wrench wont loosen it up?!?!
I think only the US uses the term "wrench"?an impact wrench is something you hook up to an air compressor and spins with the force of the air...i dont know what your talking about but that is what it is....and it should get that bolt off no prob...i dont know what wrench you are thinking of...rattle gun may be a slang for it???
I agree, definately the right way to do itPersonally I would not like the idea of using impact against the gear teeth in the trans especially if the bolt is jammed or very tight some how. I would throw the old chain back on or the new chain (unless it's a 520 and won't fit) and use the rear brake method.
Some bikes have a huge nut on the countershaft and, just like the clutch hub nut, a rattle gun is unlikely to damage it.honestly i thought the same thing..that it would crack the bolt or mess something up but a buddy of mine works in a shop and they use the impact wrench on these bolts and many other ALL the time at the shop ( which is a honda certified service center )and have never messed anything up using one...even that book i mentioned says if you have one to use it...and they always tell you the things NOT to do in that book
I agree, the bigger nut is a better way to do it but it's heavier and increases the rotational mass of the shaft.ya my 08 has a small nut on it...probab2ly this m10 ur speaking of or similar...my 04 R6 had a BIG one...i kinda wish the cbr had a big one...seems a little more safe...but im sure honda knows what is needed
