Which coupler is on your machine?

Pick the system on your machine and we put it in your enquiry. We check the bracket before we send the quote.

How to measure your coupler
213

Not sure which system it is? Three measurements tell us which bracket you need.

  1. Measure the diameter of both pins.
  2. Measure the distance between the pin centres.
  3. Measure the width between the inside faces of the ears.

If the coupler has a make or type printed on it, send that too.

Send me the spec sheet for my machine

Before you order: check the interface

The weight class of the Komatsu PC58MR-5 sizes the attachment. It does not tell you the pin diameter, the pin spacing or the stick width, and those decide whether an attachment fits. Measure them on the machine, or send us the measurements of the bucket it runs today.

On a mini excavator the weight of the attachment counts for more than on a larger machine, because every kilogram of bucket is taken from lift capacity and stability. A narrow trenching bucket and a wide grading bucket are the usual pair, and many machines run a small quick coupler to change between them.

Quick coupler brackets at this weight

In our model tables, the attachments listed for the Komatsu PC58MR-5 at its weight are built with these brackets. Each code opens the models that list it.

  1. Measure the diameter of both bucket pins.
  2. Measure the distance between the pin centres.
  3. Measure the inside width between the stick ears.
  4. If the machine runs a quick coupler, note its make and type.
