Replacement chain and sprocket set
« on: November 25, 2018, 03:59:15 PM »
I started the preparation for the installation of a new chain and sprocket set. This is inside the engine sprocket cover after 2.5 years 15.5K.



And this is it after cleaning



I've bought a impact wrench that I'm hoping will do the job of removing the sprocket nut, it's over spec at 480Nm - the nut is torqued to 147Nm.

I've got the sprocket nut soaked in WD40 and will leave it for 24/48 hours

Subscribed for updates.

Most interested in hearing how you get the front sprocket nut off. Keen to have a go at this when my time comes. The front sprocket being the only thing that concerns me a bit!

I normally get someone to sit on the bike and hold the back brake on, before you take the chain off, of course.
The nut usually come off quite easily. :046:
If it looks to good to be true, buy it.

I needed my chainset replacing just recently but bottled it entirely (as I weighed up the cost of the gear I'd need and heard horror  :005: stories about the front sprocket nut) so I got the guys at Corby to do it when they serviced the bike. It is now running like new - a mahooosive difference.

Good luck :028: and post the photos plz (v. interested if the stories are true).

I finally got around to removing the front sprocket this morning - SUCCESS!  :celebrate:

With the bike on the side stand, front brake tied on, rear brake weighted on (small sledgehammer) and front and rear wheels chocked I held my breath and brrrrr, brrrr (thought I saw signs of movement), brrrr off it came!

This is the impact wrench that I used.

It's a bit more expensive than a couple of others, but it's a solid piece of kit and comes with four separate sockets (rather than two combined sockets) and a 6m mains lead which is great. I had to buy a 27mm impact socket though.

Very happy.

All fitted today, went really well. I've just got to adjust the chain tension, torque everything up, put the engine case and fairing on and give her a clean.

One good thing about doing this yourself is you can give everything a good clean whilst the bike is exposed, including the rear wheel whilst removed.

Front sprockets - slight hooking to old sprocket.

Front sprocket holder before cleaning. Not so bad.

I think that's pretty normal wear for a chain and sprocket set that's due replacement. I've seen very much worse.  Remember that the front sprocket wears 3 times faster than the rear.  Which is why I don't mind fitting a relatively fast wearing alloy rear sprocket.
