FAQ
Q: How do I confirm these bearings fit my Perkins D3.152 engine? A: Please verify your engine’s serial number and cross-reference the OEM part numbers 31123411 (main bearing) and 31131171 (connecting rod bearing) with your engine’s parts manual. This set is specifically designed for the standard size D3.152 engine. If your engine has been previously reconditioned with undersized bearings, this standard set may not be suitable.
Q: What is the installation procedure for these bearings? A: Installation should be performed by a qualified diesel mechanic. Ensure the bearing surfaces and journals are clean and free of debris. Apply clean engine oil to the bearing surfaces before installation. Torque the main bearing and connecting rod cap bolts to the manufacturer’s specifications for the D3.152 engine. Always check bearing clearance using Plastigage to ensure proper oil film thickness.
Q: How should I store these bearings before installation? A: Keep the bearings in their original packaging in a clean, dry environment at room temperature. Avoid exposure to moisture, dust, or extreme temperatures. Do not remove the protective coating until immediately before installation to prevent contamination or corrosion.
