Sprockets Filing down the drive sprocket?!

[Bean Oil]

Usually the teeth have to be filed so they are slightly more "triangular" when viewed on edge....mostly towards the tips

Thanks, Andy... I think I know what you mean.

You mean looking straight down onto the top of a tooth and adding a bit more taper but just the 3/16 to 1/8 near the tooth's tip?

Difficult to describe without pics...

i noticed someone was talking about how the tensioner doesnt spin, get a faw washers and you'll be fine

Good luck man."unquote

HI Bean,

Yes, I believe you have it...the taper goes from the thin side of the sprocket to the other thin side is about how I'd describe it....I will try to post a pic later if you need but I'll have to take a picture of a rear sprocket but the idea is still the same for the front sprocket.

Just incase anybody is interested, here are Warren's instructions on how to remove the drive sprocket:

" * Slip out the bucking bar (loose rod that pushes the clutch in).
* Use plug spanner to remove large nut.
* Screw the screw tool into inner thread of small sprocket
* Turn the inner piece of screw tool clockwise to lift out the sprocket
* Put new sprocket on and lightly
tap into place (be sure to keep key in the slot)
* Replace large nut with plug spanner and slip bucking bar back into place.
* Put a dab of grease on bucking bar and sprocket whilst you have it all open.

That all should take you 5 minutes and you will have no problems afterwards."

Cheers,
Mike

Hey guys, little problem.

Got my new sprocket, went to take the old one off. Managed to get as far as taking the nut off thanks to this thread:

Now I'm attempting to use the screw tool to remove the sprocket, but for the life of me I can't stop the engine from turning over. As soon as I tighten up the bolt, the whole thing just starts spinning in the breeze.

...help?

Stop it from spinning by placing a 22mm spanner(or adjustable shifter) around the lower part of the removal tool and while holding that securely turn the 14mm bolt...you'll see where it's meant to fit.

PS...also see my other post about making sure the sprocket nut is tightened securely.

Dumb Q, but did you remove the clutch "bucking bar"? Either way, I think you still have to hold the sprocket from turning (obviously).

Okay... I go now.

Oh god nevermind, I must have been way too tired last night. Got up this morning and figured it out, then came on here and realised the stupid question I asked.

Cheers guys,
Mike

please, introduce yourself, just like you'd be expected to in real life.

The sprocket on my motor is 1/4" thick, the rear sprocket is 1/8". I'm assuming that running 420 chain won't work. Any suggestions? I've been looking around and haven't found a front sprocket for 415 chain that will fit the splined shaft on the motor. I'm kinda inclined to fasten the sprocket in a drill press and take a good grinder to it.
