FAQ

Q1: How do I confirm this bolt set is the correct part for my specific Yanmar 4TNV88 engine?
A: While engineered for the 4TNV88 platform, we highly recommend cross-referencing the engine’s serial number and any existing bolt part numbers. Our technical team can assist with verification if you provide these details to ensure a perfect match for your application.

Q2: What is the recommended installation procedure and torque specification for these bolts?
A: Critical fasteners like cylinder head bolts require a specific torque sequence and value, often in multiple stages (e.g., initial torque, angle torque). This information is defined by the engine manufacturer (Yanmar). We provide OEM-specification bolts, but you must follow the official Yanmar 4TNV88 service manual for the exact installation procedure to prevent engine damage.
