FAQ

Common Questions

How many cylinder head bolts do I need for my engine?

This bolt is sold individually. The quantity needed varies by engine model. Most Kubota 4-cylinder engines (V2203, D1703, etc.) require 8-12 bolts per cylinder head. Check your engine service manual or count existing bolts before ordering. Call (818) 261-3896 if you need help determining the correct quantity.

Can I reuse old cylinder head bolts?

For critical engine rebuilds or after head gasket failure, we recommend using new bolts. Cylinder head bolts can stretch during initial installation and may not provide proper clamping force if reused. Always inspect existing bolts for damage, corrosion, or elongation before deciding to reuse.

What torque specification should I use?

Always follow the torque specifications and tightening sequence in your engine’s service manual. Kubota engines typically require a specific torque value and multi-stage tightening pattern. Improper torque can cause head gasket failure or engine damage. If you don’t have the service manual, contact a Kubota dealer or certified technician.

What's your return policy

We offer free returns within 30 days if the part doesn't fit or you're not satisfied. Parts must be unused and in original packaging.

Do you offer technical support?
