FAQ

Q: What is the function of the Hydraulic Cylinder Tightening Valve (422-00055)?

A: The Hydraulic Cylinder Tightening Valve is a critical component used to apply and maintain a precise clamping force on the cylinder head or liner. It uses hydraulic pressure to tension the cylinder head bolts or studs evenly, ensuring a perfect seal between the cylinder head and engine block, which prevents leaks and engine failure.

Q: How can I confirm this valve fits my Doosan DB58 engine?

A: The primary identifier is the part number 422-00055. Please cross-reference this number with your existing valve or your engine’s parts manual. While this valve is specifically designed for the DB58 engine model, variations may exist. We recommend confirming your engine’s serial number to guarantee a perfect match.

Q: What is the recommended installation procedure for this valve?

A: Installation should be performed by a qualified diesel mechanic following the engine manufacturer’s service manual. The process typically involves cleaning the mounting area, applying the correct thread lubricant (if specified), and using a hydraulic torque wrench to apply the specific pressure and angle as per the engine’s technical specifications. Improper installation can lead to engine damage. Always follow the correct tightening sequence and torque values.
