 My Mk2 (sc64) nut on right hand side.

The SC58 and SC64 are both the same, the axle is fitted from the sprocket side (left) with the washer/nut on the brake disc side (right) the nut then tightens in the same direction as the forward rotation of the wheel which eliminates the risk of the nut working loose due to vibrations combined with rotational forces from the wheel/ axle. You may think at 72 lbf-ft (98 Nm) the rear axle nut is going nowhere, however, it is a re-usable self locking nut with a friction ring and clamp cut into the top threads (U-nut) that clamp can fail! Top tip - carefully inspect the axle nut to make sure there is sufficient resistance when the top threads of the nut enter onto the axle bolt threads, there should be sufficient resistance to prevent the nut from being spun onto the axle by finger pressure alone.

How these axles get fitted incorrectly is a right handed schoolboy error and I've seen it many times. The home mechanic sits behind the motorcycle struggling to align the wheel, distance collar, swing arm and chain adjusters, when all are aligned the axle is thoughtlessly picked up in the right hand and incorrectly fitted from the right hand side. Top tip - Lay the parts out in the order removed and RTFM to make sure the parts were fitted correctly before you got to them.

decided to put it all back together as normal , cable tie on it (the gasps the shock horror ) feels sturdy enough if it goes for a hop it goes
