C2.4 450-3206 Diesel Engine Assembly Overview
The C2.4 450-3206 Engine assembly manufactured by Tatan is a 2.433-liter inline 4-cylinder turbocharged direct-injection industrial diesel powerplant belonging to our Diesel Engine Assembly classification. Engineered specifically for Caterpillar CAT 306, 306E, and 306E2 6-ton compact excavators, replacing your worn or failed engine core with a Tatan complete turnkey assembly stops crankcase oil spitting, restores 36.5 kW (49.6 HP) rated output at 2400 RPM, and cures hot-idle oil pressure loss under continuous hydraulic pump load.
Coupled directly to the machine’s main hydraulic pump and governing the C0070 main control valve, this C2.4 450-3206 Engine incorporates an induction-hardened forged steel crankshaft, a direct-injection crossflow cylinder head, an internal gear oil pump, a wastegated turbocharger, and an in-line mechanical fuel injection pump, ensuring 100% direct bolt-on installation with flywheel housings and chassis mounts.

C2.4 450-3206 Engine OEM Diagnostic & Troubleshooting Guide
Use this technical guide to diagnose common Cat C2.4 DI Turbo diesel engine symptoms on your Caterpillar 306 excavator:
| Engine Fault Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Severe engine lugging & black smoke under load | Wastegated turbocharger actuator diaphragm rupture or in-line injection pump delivery valve wear, failing to build boost pressure above 160 kPa. | Replace with Tatan complete C2.4 450-3206 Engine assembly fitted with brand-new factory-timed injection pump and matched turbocharger. |
| 2. Coolant boiling & expansion tank bubbling | Combustion gas blown past cylinder head gasket on rear cylinders due to localized thermal distortion in compact 6-ton engine compartments. | Install Tatan new engine with factory-torqued MLS head gasket and precision surface-milled parent block face. |
| 3. Heavy crankcase blow-by & oil spitting | 87mm cylinder bore micro-scoring or stuck top compression rings allowing combustion pressure into the oil pan. | Install Tatan new C2.4 turnkey engine; flush radiator cooling fins and install fresh dual-element air filters. |
| 4. Oil pressure lamp flickers at hot idle (< 0.12 MPa) | Excessive crankshaft main journal bearing clearance or worn trochoid oil pump rotor losing delivery volume under operating heat. | Replace complete engine assembly to maintain factory oil pressure (> 0.35 MPa rated / > 0.15 MPa idle) and prevent crankshaft seizure. |
