FAQ

Q: How do I know if I need a 0.25mm oversize bearing for my Kubota V1505?
A: A 0.25mm oversize bearing is used when the crankshaft has been ground down by 0.25mm during a rebuild. You must measure your crankshaft journal diameters with a micrometer. If the journal is 0.25mm smaller than the standard size (e.g., 40.00mm becomes 39.75mm), you need this oversize bearing. If the journal is still standard size, you should use standard (STD) bearings.

Q: Can I install these bearings myself, or should I use a professional mechanic?
A: While a skilled DIY mechanic can install main and rod bearings, it is a precision task that requires specific tools like a torque wrench, plastigage, and a micrometer. Incorrect installation can lead to engine failure. We strongly recommend having this work performed by a certified diesel mechanic or machine shop to ensure proper clearance and alignment.

Q: What is the recommended maintenance after installing new bearings?
A: After installation, a proper engine break-in procedure is critical. This typically involves running the engine at varying speeds (not constant high RPM) for the first 50-100 hours. You should also perform an initial oil change after the first 50 hours of operation to remove any wear-in particles. Regularly check your oil pressure and listen for any unusual knocking noises, which could indicate incorrect bearing clearance.
