TRW ps pump question

You can see in the pics of the shaft, someone mentioned the "dulling" on shaft and that may be a sign that needle bearing was toast.
Approx 2/3 of the way down shaft.
The LH end of shaft is supported by bushing in pump body.
Thanks a lot, now I understand the inner workings. So I guess the kit did not include the bushing, which may or not be a problem in future rebuilds. I can understand a bearing only in the front as that is where all the load is. Front bearing and rear bushing are submerged in oil, haven't seen either give out, very reliable. Until your's. Thanks for the education.
