Welded to EN ISO 3834-2. Agree it as a standing term of supply and the EN 10204 3.1 certificate ships with every attachment. You also get the CE declaration of conformity for every quick coupler and hydraulic attachment. See the certificates.

Before you order: check the interface

The weight class of the Caterpillar 325 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 325 at its weight are built with these brackets. Each code opens the models that list it.

Brackets we build attachments with in this weight range. Not a confirmed fit.

  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.

What the 325 figures mean for its attachments

  • Its auxiliary circuit is rated at 51 l/min and 140 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 429 l/min at 350 bar. That is the pump output of the whole machine, not the flow an attachment gets.
  • Caterpillar lists this quick coupler for it: Pin Grabber QC B. The bracket on every attachment has to match the coupler.
  • It digs down to 6,700 mm. That is the deepest trench it can open.
  • Its maximum reach is 10,130 mm.
  • It dumps at up to 8,540 mm, so a truck or skip side has to sit below that height.
  • Its arm is 2,900 mm long.
  • Caterpillar lists buckets from 600 to 1,350 mm wide for this machine.Our sizes in that range: DB - heavy duty digging bucket (DB-300); DBF - flat-top digging bucket for quick coupler (DBF-300); DSX - Nordic heavy duty digging bucket (DS-HD-300)
  • Caterpillar lists bucket capacities from 0.46 to 1.59 m³.
  • Bucket breakout force is 150 kN and arm crowd force 106 kN. That is the force a bucket or ripper works with at the tooth.
  • Caterpillar gives a lifting capacity of 7,450 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
  • For transport it measures 8,890 x 3,170 x 3,210 mm (length, width, height).

325: what the brochure names

Features Caterpillar names in its own brochure for the 325. Some of them may be optional, so check the machine's spec before you order.

  • An engine that meets EU Stage V.
  • Use with a tiltrotator.
  • Telematics for tracking the machine remotely (VisionLink).
  • Work modes you select from the cab.

From Caterpillar's published brochure. We keep the source document on file.
