Excavator Bucket Pin Size Chart All Makes & Models
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).

Can you tell me iof a bucket from a Cat 301 will fit a Komatsu PC15MR x1 ? Thank you
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!

looking for cat 390f bucket pin details, is it possible to get that?
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 everything though to be sure.
Hope that helps!
