First time buyer of a dozer and wanted to ask about what seems to be a concern. Would repair to only one half of an undercarriage be a red flag? So far I have inquired on a Komatsu D31 where the seller is including one sprocket and chain to replace what I could see in the picture was some pretty sharp edges to the teeth. He didn't mention nor could I see anything on the other side. Another seller replaced one final drive on a Case 450C along with both tensioners. No elaboration as to what led to one side going out. Both of these were not viewed in person.
I was under the impression that if something on these undercarriages is worn to the point of needing replacement, then both sides should be addressed or else if only one side is, that the other would soon be needing the same done to it as well in a sooner than later time frame. Am I correct with this analogy or are there instances where the untouched half lasts?
Also, is there a general standard thickness for idlers to help determine if what I am being told is the wear percentage as a guide to judge the sellers claim? Kind of like tire tread depth having its rule of thumb for what is too minimal, or does each dozer manufacture have its own specifics that I wou8ld have to look up beforehand when going to inspect in person?
Sorry for the long post, I just didn't want to gamble away the amount of money involved, only to have it cost me even more in the end. Thank you all for your time and help.
