FAQ

Q1: How do I confirm this bearing is the correct part for my specific Caterpillar 3406 engine?
A1: The part number 261-3450 is a primary identifier. For absolute certainty, we recommend cross-referencing this number with your engine’s service manual or providing your engine’s model and full serial number (ESN) to our technical support team for verification before ordering.

Q2: Is this sold as a single bearing or as a full set for one connecting rod?
A2> This part is typically supplied as a matched set, including both the upper and lower shell bearings required for one connecting rod. Please confirm the quantity per package with your sales representative, as bulk orders for complete engine sets are also available.

Q3: What are the critical installation checks for this connecting rod bearing?
A3> Proper installation is crucial. Always: 1) Clean the rod and cap bore thoroughly. 2) Check the bearing clearance with Plastigage or micrometers as specified in the service manual. 3) Ensure the bearing tangs align correctly with the notches in the rod and cap. 4) Lubricate the bearing surface with clean engine oil or assembly lube before final torque. Incorrect clearance is a leading cause of premature bearing failure.
