Applications & fitment
Documented application references
- Cat 305.5E/305.5E2 mini excavators use C2.4 variants; confirm machine serial and arrangement before claiming fit.
- Cat 903D compact wheel loader also lists a C2.4 variant.
Application examples identify documented uses of the engine family. Confirm fitment against the machine and engine serial numbers before ordering.
Confirm your engine match
- Request the included-component list and test record for this assembly.
- Provide the existing engine serial and arrangement plus the machine PIN. Compare mounts, flywheel housing, cooling and fuel systems, electronics, accessories and emissions configuration.
- Any machine-specific rating shown above is a reference; match the supplied engine rating from its data plate.
For fitment checks, availability or a quote, email info@nyengines.com with your engine data-plate photo, machine details and required assembly scope.
Buyer guide
- The C2.4 appears in different compact machines: Cat's 305.5E excavator reference is a direct-injection Interim Tier 2 version, while the 903D loader reference is Tier 4 Final. Match the emissions label and machine serial, not just the C2.4 family name.
- Even among Cat mini excavators, documented C2.4 output changes by machine: Cat lists 30 kW at 2,200 rpm for the 304E2/305E2 and 32.9 kW at 2,200 rpm for the 305.5E2. Confirm the required rating from the target machine.
- For a replacement, compare the injection and emissions hardware with the existing engine. Cat identifies the 305.5E C2.4 specifically as direct injection, rather than making that a blanket statement for every C2.4.
Buying questions
Does 'C2.4' identify one emissions configuration?
No. Cat documents a C2.4 in the 305.5E with Interim Tier 2 compliance and another in the 903D with Tier 4 Final compliance. The actual engine label is decisive.
Is the same C2.4 power rating used in all Cat mini excavators?
No. Cat's E2 range brochure lists 30 kW at 2,200 rpm for 304E2 and 305E2, and 32.9 kW at 2,200 rpm for 305.5E2. These are machine ratings, not a guarantee for this assembly.
