While replacing chain, sprockets and rear disk break rotor, I find it too hard to unscrew the front sprocket. Apart from the washer that I unfolded, how do I unscrew this? Clockwise or counterclockwise?????

counterclockwise

thanks cca, I did try this way with no luck. It was so hard that the idea of it being the other way crossed my mind.
I guess I need an air impact wrench gun to do it.
Many thanks again mate

Each time I change my sprockets & works for me.....put front wheel against a wall,select top gear (too much engine compression in first etc) and with someone pressing on rear brake pedal it should come off OK.

I use my 32m socket with a short extension bar and loosen same off.

Other than that,an impact driver gun will loosen it off at any local garage for a fiver?

I normally use a small 20cm socket wrench but when that is not enough (like removing the wheels of the car after a winter on salty roads) i have about a meter of 1" pipe that fits on top of it. I've actually cracked a quality 17mm socket with that (and then took a socket from impact wrench enstead to get the damn wheel off).

When i replaced the chain kit a week ago i again had to find the long pipe and my 14 year old son had to almost stand with all his weight on the brake pedal or the rear brake would slip...

It had been there since it left the factory in 2011 and the nut had some surface rust.

The new one was tightened with a torque wrench, but I should probably have replaced the nut. I'll do that next time.

Proper like that "locking" 5mm bolt through the chain idea. I normally put a small crowbar through the rear sprocket slots and then onto the upper or lower face of the swinging arm which locks wheel rotation . With the chain attached in this way, front nut torquing is easy, just not professional. I'll be using that bolt method from now on......hash tag - definitely still learning after 40 years on two wheels.

Well I've replaced the front sprocket and the rear, plus chain and used the bolt idea first time in 40 years. It is by far the easiest way to do it.

No need for walls, buddies, crow bars, or even putting the bike in gear.

You don't even need a centre stand if you can jack up the bike.

Just use 2 bolts fore and aft of the axle through the old chain. It doesn't matter if you have already cut the chain.

Don't forget it's 120 Nm or to replace the tab washer.
