    Maybe make the claim Jim and up grade the machine, the repair looks like a very job to me and shouldn't give any more trouble.............

      Yeah ... agree on both counts ... that should fix it and take the bending moment off the pinion causing the failure

        ..please excuse my ignorance...

        Hello Jim, if you get a minute could you add a photo from a couple of metres away from your machine as I'm having difficulty placing where the problem lies.
        Also, is your Blacksmith a traditional blacksmith as in forge and tongs or is he a modern master of machining, welding etc. [I was going to ask if he was a farrier type blacksmith but that might appear too ignorant........]

          Right jack, the first picture shows the new tie bar support thingy going on top of the pin that holds in the ram for the side shift of the dipper that's where the problem lies as its the JCB casting that broke! D you know where I mean?

            ahh, yes, so your smithy added that extra support above the stay to totally counteract the bending moment as Muz said. Apologies for being slow in the uptake. Nice welding. I'm looking at a photo of 'your' machine from the intraweb - very pretty on the eye.

              Hi Jim, how is the repair holding up? Is the machine getting much work?

                Hello sir,

                The repair is holding up just great! Really contemplating trading it in in September as I will be 2 years into a 3 year agreement but will wait and see. The digger gets loads of work and I have a bug job coming off soon and it will be working pretty much full time for a month!

                          Got to say mine is late 2007 and exactly the same broke on mine, been welded 3 times now, last one has lasted 1500hrs and still going, this is a design fault the machine has paid for itself 3 times over, few sets track idler bearings, has to weld the hinges few times the cab tilts on, few sets of door windows, rubbish design, all they need is pins whereby you can lift the door off in hot weather, if now got a leak from between the valve, evidently an O ring, JCB want 450 for a set to recondition whole block, can't buy separately, does anyone know the size, thanks
