Frequently Asked Questions

What ignition switch fits a Cat 320D excavator?

Broken Tractor carries the 2552751 key start ignition switch for Cat D and D2 series excavators, including the 320D, 320D FM, 320D GC, 320D L and 320D LN. The same switch is listed for the 307D, 308D, 312D, 312D2, 313D, 313D2, 314D CR, 315D L, 318D L, 318D2 L and 319D L. Because fitment can change by serial number, compare part number 2552751 to the switch on your machine before ordering.

What starter and alternator fit a Cat 308E2 mini excavator?

The 385-5044 starter motor and the 385-5043 alternator both fit the Cat 308E2, along with the 308E2 CR and 308E2 SR. Both parts are also listed for the 308, 308.5, 308E, 308E CR, 308E SR, 309 and 310. The two part numbers are close, so check that you are ordering 385-5044 for the starter and 385-5043 for the alternator.

What water temperature sensor fits a Cat 305E2 excavator?

The 377-6954 water temperature sensor fits the Cat 305E2 and 305E2 CR, plus the 304E2, 304.5E2, 305.5E2, 306, 307.5, 307E2, 308, 308.5, 308E2 CR, 308E2 SR, 309 and 310. We also offer the 377-6959 DPF pressure sensor for the same list of Cat mini excavators. Sensor specs can vary by engine tier, so verify your machine configuration before ordering.

What speed sensor fits a Cat 320E excavator?

The 2380120 speed sensor is listed for Cat excavators in the 311D through 320E range and the 321D through 336GC range. For position sensing, we carry the 140 degree rotary position sensor 2662337, which fits Cat excavators from the 311D through the 390DL. Match the part number on your old sensor to confirm the correct replacement.

How do I make sure a Cat excavator electrical part fits my machine?

Start with your machine's model and serial number, because Cat excavator electrical parts span B, C, D, E and F generation machines and fitment can change within a model. Sensor and solenoid specs can also vary by engine tier, so confirm your machine configuration and match the part number on the old component when you can. If you are unsure, call (800) 909-7060 and the parts team can help confirm the right part.
