Finally got around to pulling apart the pins on my Takeuchi TB153FR after I broke the pin again frost ripping As I suspected on the one side the entire bushing is gone and it's worn into the stick, from a quick tape measure it's 1/16" one way and 1/8" the other way. The odd part is the other side there is still lots of bushing left for about 2/3 of the way then nothing left. I attached a few pictures. Is line boring a must? I called one place and they figured you could weld the loose end of the bushing, or fill in a bit of the worst spots grind it, or even try to get a machine shop to taper the bushing for a better fit? I was quoted from $700-$1000 for line boring
I pulled all 4 pins at the bucket linkage, 1 has zero play whatsoever, i'm assuming I should replace anyway? Should I also replace the pins in all of them, 2 for sure but the other 2 don't seem worn at all. Dealer said in most cases people replace bushing and the pins last 2 sets of bushings? Machine has 4000 hours on it now, so either way it will be a long long time if parts last even 2000 hours.
Also i'm curious at what point should a pin/bushing be replaced? As soon as there is any play? I noticed the bushings are quite big and it would take a ton of play before anything is worn past the bushing. There is some play at one of the pins where the boom attaches to the house, not a lot but it is there.
