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.
Before you order: check the interface
The weight class of the Caterpillar 434E 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.
A backhoe loader digs at the rear and loads at the front, so the rear bucket is chosen for trenching and the loader bucket for moving material. The rear quick coupler, where the machine has one, sets the bracket every rear attachment needs; the pin and stick checks below still decide the fit.
Quick coupler brackets at this weight
In our model tables, the attachments listed for the Caterpillar 434E 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.

What the 434E figures mean for its attachments
- The main pump delivers up to 125 l/min at 227 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 4,364 mm. That is the deepest trench it can open.
- Its maximum reach is 5,660 mm.
- It dumps at up to 3,759 mm, so a truck or skip side has to sit below that height.
- Caterpillar lists buckets from 228 to 914 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-95); GPO - GP bucket with perforated bottom (GPO-95); GPL - general purpose digging bucket (GPL-95); BDP mini - clay digging bucket for mini-excavator (BDP-90); PDP mini - skeleton BDP stone bucket (PDP-90)
- For transport it measures 6,120 x 2,368 x 3,623 mm (length, width, height).
