Hi Sbtragic and CyberJack,
Well this one is a typical example of how many of the twin railers are today only around 2 minutes away from total failure.
It's lucky that you've caught this one before it totally cut loose and failed causing frame twist and misalignment. This damage is the sole responsibility of a flogged out clutch which has come about by it's owner not doing routine maintenance and checking the tightness of the cotter pin securing nut that's there primarily to hold the clutch body firmly on to the PTO shaft of the engine and eliminate any movement.
As Jack has mentioned above this is the perfect candidate for the "Jones Gusset Repair Method" which member "Mr Jones" was the founder of on this website.
If this repair is done correctly you'll find that the machine will outlast all of us. Just make sure that there is some type of corrosion protection between the gusset and the existing rail and do not leave them a bare steel prior to welding as you'll never be able to correct rust that will form between the two metals.
It also pays if you can after painting, create a hole in the surface finish that's not seen on the underside and force oil in between the two pieces, thus making it hard for rust to start in the first instance. A bit like the days of putting fish oil inside car doors and tail gates so that it finds its way into the seam folds of the body panels.
Please supply photos along the way to make this a reference thread for future readers.
Keep up the good work.
Cheers,
BB.
