Replace my front

[johncam4]

I dont have much time to work in my gs this weekend...I wanna put my new front sprocket on....what do i need to know so there are no surprises?.   Specifically the clutch cable that runs into the casing.

No suprises.  There really is no need to take the whole cable loose.  the case can be moved far enough out of the way to remove the front sprocket.  You will need a pair of snap ring pliers to remove the front sprocket.

just for my own future refrence, what are snap ring pliers, and over in the thread about forks, everyone is talking about impact wrenches, what are those?

snap ring pliers are pliers with two little nubs on the end. they are normaly H shaped so that when you insert the nubs into the two corosponding holes in the snap ring and squeeze the handles the nubs spread apart expanding the snap ring.   impact wrenches are the same thing as impact guns, the things that you see the tire guys using when you get new tires,  they are just a tool that uses compressed air to turn a socket. see links below for pictures.

feel free to ask any questions anytime, if you don't know you don't know now is the best time to learn, and the only dumb question is the one not asked.

i took the cover completely off on mine, did swap and replaced cover. no ill effects :dunno:    oh yeah, you WILL have to adjust chain tension on her, goin down one tooth has that much effect on it

unless you are replacing with another 16t. 15t requires chain adj.

For a few hints on starting the process, see this post which I wrote to explain how to clean out built-up chain lube deposits behind that left-side cover.  I didn't make it very clear in that post, but like someone else said you don't need to mess with the clutch cable at all.  Leave it attached, and the left-side cover will just dangle from it.

Once you remove the 5 bolts, all you need is the snap ring pliers already mentioned.

HINT: I think you can pull the sprocket laterally, right off the splined shaft (depending on how tight your chain is).  But it can be tricky to line the new sprocket up with the splined shaft while pulling the chain tight at the same time.  It's easier if you're replacing a 16-tooth sprocket with a 15-tooth one.  If you're sticking with a 16-toother, try it first.  If you can't get the sprocket on, introduce some slack by loosening the rear axle (and chain adjusters) and pushing/kicking the tire forward half an inch or so.

i don't have those kind of pliers so i used just regular needlenose pliers...it took about 3 mins but i got it off....you can use any pliers that can fit between the ring and grab it a little.....just don't squeez the pliers because you want do anything like that  :lol:

pull them apart

What davipu said, plus: The snap ring pliers he described aro those for shaft snap rings (not sure if the term is correct in English; those tht go on from the outside). There's a flavor of this tool that is X-shaped, working more like cionventional pliers, that is used on inside snap rings.

Impact wrenches also come in a simpler flavour. Those are driven with a hammer. The wrench converts the blows in rotary movement. Very worthwile investment, as the axial blow both ensures that the bit bites well into the slot in the screw and helps to loosen tight screws.
Not Sure if the hammer operated impact wrench would provide enough "inertia countertorque" from the damper rod to loosen the screw in a fork, though.
