Good post. Hope we get some answers to those questions, not to cast blame, just to educate ourselves.Do you happen to know how many hours were on the original chains when they were replaced.?
Is the machine Serial Number below B9D01578, B9G00158, B9M00596, or D9G00115.?
Did Cat also replace all the sprockets when they replaced the chains under warranty.?
How many operating hours on the replacement chains.?
Also do you have any photos of the broken link taken from the side as opposed to from the end as per the photo above.? I need to see the shape of the side plates (this might be important).
Also are there any identifying marks stamped on the link side plates.?
