| I worked on those MT-Challengers from the beginning in 2002 until about 2013. There has been more than one "up-date" or improvement to the reaction arm bearing problem over the years. But, I never ever saw the failure rates that are being talked about going on now. I know for a fact in the early years the oil change interval (less than 2 quarts) was never often enough. I know for a fact some weren't even having BOTH drain plugs removed to drain the oil. The more road travel there was, probably led to higher failure rates overall. Improper torquing of the axle wedge bolts were said to have an effect on bearing life. Sounds to me like whomever their supplier of these housing is, needs a serious quality audit. Old school warranty failure rates used to be anything over a 2% failure rates meant there was a problem that needed to be addressed. I think AGCO should consider offering a 5 or 6,000 hour warranty on these bearings with no time limit. The problem with that for them would be, how do they "know" the customer has been faithfully changing and using the correct type of oil all those hours ???? By the way, I always used 75W-140 synthetic oil instead of whatever Cat or AGCO was recommending at the time and that too has been a revolving thing. | |
