Troubleshooting & FAQ
How do I know if this is the right bearing shell for my engine?
This part is specifically for Parsun F115 models. It is the "B" position (lower) shell and is color-coded "Red" for a precise size tolerance. Always verify the part number PAF115-05010003-3 and visually compare your old part to our photos to ensure a match.
What does the "Red" color code mean?
The "Red" color indicates a specific thickness and tolerance standard for the bearing shell. Using the correct color is critical to ensure proper oil clearance for the crankshaft, which is vital for engine longevity and performance.
What are the signs of a failed crankshaft bearing?
Common symptoms of a worn or failing crankshaft bearing include a deep knocking or rumbling sound from the engine that may increase with RPM, low oil pressure warnings, and the presence of metallic flakes or shavings in the engine oil upon inspection.
When should crankshaft bearings be replaced?
Crankshaft bearings are typically replaced during a major engine overhaul or when specific signs of wear or failure are diagnosed. Unlike spark plugs or filters, they do not have a fixed service interval under normal operating conditions.
Can I install just one bearing shell?
While this listing is for a single shell, it is best practice to replace bearing shells in sets for a given journal to ensure even wear and consistent clearances. Always follow your engine's service manual recommendations.

This listing is an aftermarket replacement (not OEM). It has been built to OEM-level specifications with comparable materials. All parts are manufactured in an ISO 9002 facility and are batch-inspected for quality and consistency.
What are the shipping speed and cost?
We ship worldwide quickly—typical transit time is 5–15 days. Standard shipping is free for most orders; expedited options and final costs are shown at checkout where available.
