A very unhappy gear
Further to my recent post about a frame crack, the pictured gear is why I pulled out the tranny. This is the reverse idler gear. I rebuilt the unit about 8,000 miles ago(old type pre-39 synchros gearset) with a new cluster gear, bearings, thrust washer, etc. but otherwise original gears, has worked perfectly with good shifting and no funny noises. Went to do a routine oil change and heard the "clink" of a couple of gear teeth in the pan. Surprisingly, everything else looked fine(cluster gear, low/reverse slider gear, etc) except for a disintegrating caged bearing at the front of the cluster gear.
Any ideas as to why this would happen-for now, I'm just chalking it up to "old age" of the reverse idler gear?
I've always shifted it carefully into low and reverse and there's no wear on the low/reverse slider to indicate otherwise
