FAQ

Q1: When should I use a 0.50 oversize main bearing?
A: A 0.50 oversize main bearing is required when the crankshaft main journals have been ground down by 0.50mm during a rebuild. This restores the correct oil clearance between the bearing and the journal. Always measure the reground crankshaft journal diameter with a micrometer to confirm the required oversize.

Q2: Is this a direct replacement for the OEM Kubota part?
A: Yes, this bearing set is designed as an exact aftermarket replacement for the Kubota OEM part number 15221-13010. It matches the original dimensions and material specifications. However, we always recommend comparing the new bearing to the old one before installation.

Q3: Do I need to replace all main bearings at once?
A: Yes, it is strongly recommended to replace all main bearings (upper and lower halves) as a complete set. This ensures uniform oil clearance and load distribution across all journals. Never mix old and new bearings. Always check the crankshaft end-play and torque all main bearing caps to the manufacturer’s specifications during installation.
