The attachments buyers in your market ask for first, sized for the M323.
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.
Send me the spec sheet for my machine
Pick a bucket line and we email you its spec sheet, with the sizes we build for the M323.

What the M323 figures mean for its attachments
- Its auxiliary circuit is rated at 250 l/min and 350 bar. A breaker, auger, tilt rotator or other hydraulic tool states the oil flow it needs, so choose one whose range includes this figure.
- The main pump delivers up to 306 l/min at 350 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- Its arm is 2,000 mm long.
Figures as published by Caterpillar in its own documents.

M323: what the brochure names
Features Caterpillar names in its own brochure for the M323. Some of them may be optional, so check the machine's spec before you order.
- An engine that meets EU Stage V.
- A load-sensing hydraulic system.
- Work modes you select from the cab.
- A short tail swing, for work next to walls and traffic.

Questions about the M323
- Can the M323 run a hydraulic attachment?
- Yes, if the tool's rated range covers the auxiliary circuit: 250 l/min at 350 bar.

Before you order: check the interface
The weight class of the Caterpillar M323 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.
At this weight the choice is mostly about the material. A general purpose bucket suits soil and gravel, a reinforced bucket with thicker wear parts suits mixed ground and broken rock, and the quick coupler on the machine sets the bracket every attachment needs.
Quick coupler brackets at this weight
In our model tables, the attachments listed for the Caterpillar M323 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.
