This overhaul set is designed as a direct replacement for the following Caterpillar OEM part numbers and assemblies:
Note: Always verify engine serial number for exact compatibility. Cross-reference with your machine’s parts manual.
Q1: Is this C3.4b overhaul set a direct fit for my Caterpillar 306E2 excavator?
A1: Yes, this kit is designed as a direct replacement for the C3.4b engine used in the 306E2 excavator. However, we strongly recommend verifying your engine’s serial number prefix (e.g., C3Bxxxxx) against our compatibility list. If you have a non-standard variant (e.g., Tier 4 Final), please contact our technical team for confirmation.
Q2: Does the kit include the head gasket and valve stem seals?
A2: Yes, the kit includes a complete upper and lower gasket set, which comprises the cylinder head gasket, valve cover gasket, exhaust/intake manifold gaskets, and all necessary oil seals including valve stem seals. The full gasket set ensures a leak-free seal for the entire engine assembly.
Q3: What is the recommended installation procedure for the piston ring set?
A3: The piston rings come pre-gapped for standard bore sizes. During installation, ensure the ring gaps are staggered at 120 degrees (not aligned with the piston pin). Lubricate the rings and cylinder liners with clean engine oil before assembly. Always use a ring compressor tool to avoid breakage. Torque the connecting rod bolts to the manufacturer’s specification (typically 30 Nm + 90° turn, but verify with your service manual).
