first post, cat 259b3 rear axle bearing (?? identify)

[matthew bean]

hello, first post here, i have a 2011 cat 259b3, that i use for general landscape work. i have a pretty well rounded mechanical history (truck mechanic 3 years, industrial boiler chiller mechanic 10 years, always had old equipment that required much work (case 1845b, bobcat 642b, farm equipment etc).

my question here is, i was working with the machine when i noticed a “pop” sound, immediately shut the machine down. i found that this rear bearing AND cap have snapped in two, is this identified as a rear axle bearing?? i havent been able to find any diagrams online and its saturday so ill impatiently try to research parts until the cat dealer opens on monday but havent had much luck.

if anyone can help identify this bearing and or part numbers it would be greatly appreciated , i attached a picture as well (it is only showing one picture uploaded, the bearing sits right behind the sprocket of the final drive)

also to add, i bought the machine 3 months ago and had kept up with all greasings but i feel this bearing was neglected (it didnt take grease easily at first)

Sorry I did get back sooner, serial # is FTL14669, i got the new 9m-1328 from my local dealer, was a heck of a time getting the bearing fitted in the undercarriage. ive in stalled a new rh side rear axle assembly, now i cant get the undercarriage to slid on the new rear axle, i checked the bearing fitment on the axle shaft before i installed it in the undercarriage it was good it slid right on, Help please....

By the sounds of it you may have crushed the bearing slightly when you installed it in the track frame if you had to beat it into place. Did you buff the track frame bore with a flap wheel before you installed it.?
