Excavator bucket pin dimensions vary between excavator make and models. This makes it complex to build or fix a mount for an excavator.

Most excavators have a double pin configuration with two round pins. The measurements that are needed (shows below) to build a mounting bracket is the pin diameters (C & D), dipper/stick width (A & B) and center to center (E).

    1. Hi Joe, it looks like the CAT 301 is going to have a narrower stick than the PC15 so I don’t think that the PC15 will fit in between the bosses on a bucket built for a CAT 301.
      Hope this helps!

    1. Hi William,
      I am not 100% sure, but I would think that they are the same as a 385 which has 130mm pins, 651mm stick width and 675mm centers. I would double check everything though to be sure.
      Hope that helps!

    1. Hi Jared, a Hitachi ZX220 bucket on 80mm pins should fit a 160LX as it has 80mm pins and a slightly narrower stick (301mm vs 306mm).
      Hope this helps!

    1. Hi Andrew, CAT 302/7 has 35mm pins and I am not 100% certain but I think the KX030 is on 40mm pins. Not completely sure but I don’t think your CAT attachments will go on the Kubota.
      Thanks!

    1. Hi Matt,
      Your machine should be 40mm pin diameters, 134mm stick width and 200mm pin centers.

  1. I have a Komatsu PC28UU-2. I’m having trouble finding an exact match, but it seems like CAT 302 is very close. The pin spacing is a little bit smaller, can anyone comment on how this would affect usage? Thanks!

    1. Hi Everett,
      PC28UU should have 35mm pins with 138mm stick width and 200mm centers.
      I hope this helps!

  2. Hi Kim, I believe that machine should be 100mm pins, 386mm stick width and 500mm pin centers.
    I hope this helps!

  3. Hi Logan,
    I don’t have an exact match for the Hitachi 750, I just have 650 and 850 but I am not sure which one that 750 might match.
    ZX650 – 120mm front pin 130mm rear pin – 525mm stick width & 700mm centers
    ZX850 – 130mm front pin 140mm rear pin – 555mm stick width & 697mm centers
    I hope this helps!
