Operating weight is from the manufacturer’s published spec sheet. Pin diameter and coupler style are derived from that weight against our own tonnage bands. They are the right starting point for a machine in this class, not a statement about your specific unit. Verify both against your OEM spec, or send us a photo of the stick end and we will confirm it before you order.

We grade the fit rather than answer yes or no. Direct fit means the weight class and the mounting both check out. Fits your class means the attachment is rated for a machine of this weight and mounts pin-on. Verify first means something, usually the pin diameter, needs confirming before it ships. Telling a contractor a bucket fits when it does not is how you earn a freight claim.

Buying attachments for a Caterpillar 330
What size bucket fits a Caterpillar 330?
Buckets from 54" up to 54" wide are rated for a Caterpillar 330. The widths we stock in this class are 54". On a 30 t machine the narrow end of that range is the trenching and utility-line width, and the widest sizes are for grading and cleanup, where you are moving loose material rather than breaking ground. Go wider than the machine's rated capacity and you will feel it as lost breakout force and a tippy load at full reach, not as a fitment problem.
What pin size does a Caterpillar 330 use?
A Caterpillar 330 in the 30 t class typically runs 90 mm bucket pins on a pin-on connection. That is the number to check first, because it is the one that stops a bucket going on: the weight class tells you whether the machine can lift the attachment, the pin diameter tells you whether it will physically pin up. 1 of the 2 attachments listed here are the right weight class but drilled for a different pin. They are flagged "check pin size", and a bushing kit or a quick coupler resolves them. Pin diameter is derived from the machine's operating weight against our own tonnage bands, so measure yours or send us a photo of the stick end before ordering.
Can I run a hydraulic hammer on a Caterpillar 330?
Not from the models listed here. None of our current hammers is rated for a 30 t excavator. Call (704) 555-0140 with your auxiliary flow and relief pressure and we will tell you what is available in this class.
Will a quick coupler fit a Caterpillar 330?
We do not currently list a coupler rated for a 30 t machine in this catalog. Tell us the machine's stick-end pin centres and we will source one. Call (704) 555-0140.
