FAQ
Q: How do I confirm this part fits my specific Hino engine?
A: The most reliable method is to cross-reference your engine’s serial number and the existing part number on the valve rocker assembly. This kit is specifically for the P11C engine model. If your engine is a P11C, this is the correct adjusting bolt. Please contact our technical support with your engine S/N for verification.
Q: What is the recommended torque specification for the lock nut?
A: While always refer to the official Hino service manual for the definitive specification, a standard torque value for this style of adjusting screw lock nut is typically in the range of 15-20 Nm (11-15 ft-lb). It is critical to follow the procedure: set the valve clearance, hold the adjusting screw in place, and then torque the lock nut to specification without allowing the screw to turn.
Q: Do you provide technical support for installation?
A> Yes. We provide access to technical datasheets and basic installation guidelines. For complex engine overhaul procedures, we recommend consultation with a certified diesel mechanic or the official engine service manual to ensure proper valve timing and adjustment sequence are followed.
