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

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

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

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

What the PC14R-3 figures mean for its attachments

The main pump delivers up to 40.8 l/min at 190 bar. That is the pump output of the whole machine, not the flow an attachment gets.
It digs down to 2,250 mm. That is the deepest trench it can open.
Komatsu offers arms from 880 to 1,130 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
Komatsu lists buckets from 250 to 450 mm wide for this machine. Compare that with the bucket widths in the table above.Our sizes in that range: GP - general purpose digging bucket (GP-20, GP-30); GPL - general purpose digging bucket (GPL-20, GPL-30); BDP mini - clay digging bucket for mini-excavator (BDP-30); PDP mini - skeleton BDP stone bucket (PDP-20); DS mini - Scandinavian deep digging bucket for mini-excavator (DS-20, DS-30); KS mini - cable bucket for mini-excavator (KS-20); KSV mini - Scandinavian profile cable V bucket for mini-excavator (KSV-20)
Komatsu lists bucket capacities from 0.03 to 0.06 m³.
Komatsu gives a lifting capacity of 424 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
Engine power is 11.6 kW.

Model	Operating weight	Max dig depth	Main pump flow
PC14R-3	1.44 t	2,250 mm	40.8 l/min
Komatsu PC14R-2	1.46 t (+0.02 t)	2,250 mm	40.8 l/min

PC14R-3: what the brochure names

Features Komatsu names in its own brochure for the PC14R-3. Some of them may be optional, so check the machine's spec before you order.

An engine that meets EU Stage V.
Proportional control of the auxiliary hydraulics, for tilt buckets, augers and breakers.
Operator protection certified to ROPS and FOPS.
A load-sensing hydraulic system.

Before you order: check the interface

The weight class of the Komatsu PC14R-3 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 PC14R-3 at its weight are built with these brackets. Each code opens the models that list it.

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