Parts Compatible with the Bobcat 331 Mini Excavator

The Bobcat 331 was produced as a three-ton class mini excavator in the 300-series legacy lineup. It served as the predecessor to the current E32 zero tail swing excavator, making it a popular choice for landscaping, utility work, and general excavation in confined residential and commercial spaces.

When ordering parts, verify your serial number. The 331 shares many components with the 334 from the same era, and some parts interchange with the current E32 due to the similar size class.

Common Replacement Parts for the Bobcat 331

The ignition and door key (6693241), fuel filter with water separator (6667352), and engine oil filter (6675517) are the most common replacement items. The inner air filter (6598362), cab lock down kit (MBC9994), and press fit bushing (6803309) are popular maintenance parts.

Oil seals (6810813, 6652915), door seal by the foot (7011039), and seal by the foot (6513152) are commonly needed for service work. The thermostat gasket (6684863), bushing (6804139), and various O-rings (79K14) are available for system repairs.
