The list above is for reference. You must verify your dipper arm dimensions: 45mm & 50mm pin diameters, 205mm & 255mm arm widths, and 370mm pin centers.
Before mounting or dismounting the bucket, ensure the machine is on stable, level ground and the attachment is lowered to the ground. Always use certified lifting slings and ensure no one is in the working area of the attachment.
The bucket is the primary working tool of an excavator. Its technical condition directly affects performance and operating costs. A worn or damaged bucket can lead to reduced efficiency and increased strain on the machine.

HB400 is a designation for wear-resistant steel with a hardness of about 400 on the Brinell scale. It is a material significantly harder and more resistant to abrasion than standard S355 steel, ensuring a longer life for the bucket's cutting edge.
2. Why does this hitch have two different pin diameters (45mm and 50mm)?This is a specific design feature of the hitch system used on CATERPILLAR 428B and 428C backhoe loaders. Unlike systems with two identical pins, the CAT hitch uses different diameters and widths for the dipper pin and the link pin. You must measure this carefully before ordering.
3. Will this bucket fit a JCB 3CX or CASE 580?Absolutely not. This bucket is exclusively for CAT machines with the specific 45/50mm pin hitch. A JCB 3CX/4CX uses a 45mm / 175mm / 340mm hitch, and a CASE 580 uses a 38/45mm hitch. None of these systems are compatible.
