I had my cable snap last week wile I was out playing in the swell off Bolt Head!

Managed to get back in by attaching a rope to the engine with two ends coming around the Aframe & steered by pulling on them, beets calling the lifeboat out!

Anyway I had the same problem & soaking in DW40 & pulling like mad & hitting with a hammer at the same time no go. Tried J Walkers tip of drilling 2 holes in the wheels boss tapping them & then with 2 bolts & a bar across the centre tightened them up. Even with hitting it to no go, sheered off one of the bolts trying!
After this a couple of good tapes & more pulling & it came off, just remember to put a bolt on it before you start hitting it ore it will be good for nothing!
Just have to wait for my new Hydraulic steering to arrive so I can put it back togther.
