Changing the front sprocket

[Sofauxboho]

I'm convinced. I even have the parts. Now how are y'all getting the original sprocket off?

I've read the factory service manual and it doesn't have much to say. The stock toolkit has a 27mm stamped wrench that seems to fit, but there's no way to turn it without the handle smacking into the engine or frame.

On my Vit 701 it looks like the sprocket nut has been applied with red thread locker instead of blue (as specified in the service manual) which certainly isn't helping.

Is it finally time to go out and buy an impact driver? Anyone manage without one? Any other tricks, hints, or suggestions?

I just used a 1/2 ratchet and socket with a cheater pipe and had the wife step on the rear brake. Probably be really tough to take off with a wrench..

Heating can help especially if it's red thread locker.

I also had to use one of those pulley pullers to get the gear off the shaft.
You’ll want a good torque wrench when reinstalling that nut.

Assuming you did tap the lock washer flat before you removed the nut?

I did. And the dealership confirmed using red thread lock, which will require a torch to remove. I’ve got that, so now I’m just waiting on a 27mm socket. (And a 32mm socket for our back.)

Not quite the quick and easy afternoon project I’d been looking forward to.

you can use the wife's broom if she s not around to push the pedal

Follow-up:

It was red (permanent) thread locker. I tried to use a propane brazing torch to apply enough heat without damaging the bits of the motorcycle around the sprocket but the sprocket damper started to char and I was worried about the frame paint, clutch slave, and other important bits even when packing in wadded up aluminum foil for a heat shield.

I was able to get it too hot to touch, but was still unable to break it free even with a quality socket and cheater bar.

I ended up taking it back to the dealership where they pulled it off in seconds with an impact driver. Frustrating.

I use an electric heat gun for that.
