IT'S OFF!
But it took some doing.
400Nm ugga dugga arrived at my son's this morning. He works from home but doesn't finish until 4.00 pm. I live about five minutes walk from his house, so around 4.15 pm he arrived unannounced with a great big mother of a battery ratchet, complete with a 1/2" drive and down to the garage we went.
His toy, his game. I stood on the brake pedal (lengths of wood on standby) and we hit it with powa level 1 - 120Nm..... lots of noise, but no reaction from the nut. Up the game to Powa level 2 - 200+Nm. More noise, several bursts but this things is still laughing at us. OK, time to get serious. Level 3 - 400Nm. Loads and loads of hammer strikes, but no movement. Try again but without the short socket extensions, still no joy.
At this stage the boy is getting nervous that he may end up breaking his dad's favourite toy... "you give it a try".
I've never used a tool like this, but whatever. First burst, nope, burst, burst, buuuuurst, whizz ah ha!
I pulled the socket off the ratchet and put a t bar on... nope, that ain't going to get it off. Back on the ratchet and down to Powa 1. Drrrrrr whizzz and it's finally off and in my hand.
Looking at the nut and the first thing I see it is not a friction nut as I thought, also it has a taper at the spline end and that taper has a fair bit of red thread lock still on it.
So, it is removed and the sprocket is easily moved on the splines, so that's good, but after the beating it took, the nut is going to need replacing as it really does look like it has been hammered.... which I guess it has.
