FAQ
Q1: How do I confirm this bearing set is correct for my specific Toyota 4Y engine?
A1: The most reliable method is to cross-reference the part numbers stamped on your old bearings or listed in your engine’s service manual with our listed OEM numbers (11701-71020, 13041-71020). Always check engine serial number and model year for final confirmation.
Q2: What is included in the “machinery test report” provided with these bearings?
A2: The machinery test report details critical quality checks such as dimensional accuracy (ID/OD, wall thickness), material hardness, surface finish (Ra value), and metallurgical consistency. This ensures the bearings meet the required specifications for fit and performance.
Q3: Are there any special installation considerations for these main and rod bearings?
A3: Yes. Proper installation is critical. Always clean all engine surfaces thoroughly, use a plastigage or micrometer to verify specific clearance (do not assume it’s correct), ensure proper lubrication during assembly, and follow the manufacturer’s torque sequence and specification for the bearing caps. Incorrect installation can lead to immediate engine failure.
