Frequently Asked Questions

Which Cat excavator oil cooler fits my machine?

The right hydraulic oil cooler depends on your exact Cat excavator model and sometimes its serial number. Broken Tractor carries coolers for models from the 311 and 312 up through the 345D, 349D, 374D and 385B, with each listing showing the models it fits. The easiest way to confirm fitment is to match the Cat part number on your old cooler, such as 245-9360 for the 330D, 336D and 340D L, or 281-3514 for the 345C, 345D and 349D.

What oil cooler fits a Cat 320B excavator?

We carry oil cooler 118-9954 for the Cat 320B and 320B L, but it only fits machines with serial number 4XW00001-UP. Check the serial number on your machine before ordering. If your 320B falls outside that range or you are unsure, call (800) 909-7060 and our parts team can help confirm the right cooler.

Which hydraulic oil cooler fits a Cat 320D or 323D excavator?

Broken Tractor offers two hydraulic oil coolers for these machines, so it is important to match your part number. The 312-8338 cooler fits the 320D, 320D L, 320D2, 320D2 L, 321D LCR, 323D L and 323D2 L. The 312-8341 cooler fits the 320D, 320D L, 323D and 323D L. Because both list the 320D, compare the number on your existing cooler before ordering.

Can I buy just the oil cooler core for a Cat excavator?

Yes, Broken Tractor carries replacement oil cooler cores for several older Cat excavators. The 1516458 core fits the 330B L, the 7N-0110 core fits the 330, 330 L and 330B, and the 4I7502 core fits the 320 L, 320N and 320-A series. Match the part number on your old core to be sure you get the correct one.

What does the hydraulic oil cooler do on a Cat excavator?

The hydraulic oil cooler keeps the hydraulic fluid in the main hydraulic system at the proper temperature. When the cooler is not working as it should, the fluid runs hotter and downstream hydraulic components face more heat-related wear. Replacing a worn cooler with a direct-fit replacement brings temperature control back and helps protect the rest of the hydraulic system.
