Frequently Asked Questions

Q: Does this kit include the main bearings?
A: Yes, the Vertex WR00012 kit includes high-quality main bearings along with transmission bearings and essential seals for a complete bottom-end refresh.

Q: Is this kit compatible with a big-bore upgrade?

Expert Pro-Tip: When rebuilding the TRX420 engine, pay close attention to the oil pump assembly. Even with a new rebuild kit, a worn oil pump will starve your new bearings of lubrication. I always recommend checking the pump gears for scoring and verifying the oil pressure relief valve is functioning correctly before buttoning up the crankcase.
