Troubleshooting & FAQ
How do I know if this Standard Size (Std D) bearing is correct for my engine?
Standard size bearings are used when the crankshaft has not been machined. If your crankshaft has been ground to a smaller diameter, you will need an undersized bearing. Always measure the crank journal diameter to confirm the required size.
What are the signs of a failing big-end bearing?
Common symptoms include a knocking or ticking sound from the bottom of the engine that increases with RPM, low oil pressure, and the presence of metallic particles in the engine oil during an oil change.
Can I replace just one bad bearing?
While possible, it is highly recommended to replace all connecting rod bearings at the same time. If one bearing has failed, others are likely worn and may fail soon after, causing more significant engine damage.
Is assembly lube required for installation?
Yes, applying a quality engine assembly lubricant to the bearings and crankshaft journals is critical. A dry start without lubrication can cause instant bearing failure and damage the crankshaft.
