Q1: Is this cylinder head assembly a direct bolt-on replacement for my Kubota D902 engine?
A: Yes, this assembly is manufactured as a direct OEM replacement. It includes pre-installed valves, springs, and seals. However, we recommend comparing your existing head with the provided specifications and checking the engine serial number to confirm compatibility. For best results, replace the head gasket and bolts simultaneously.
Q2: What maintenance steps are recommended before and after installation?
A: Before installation, clean the engine block surface thoroughly to remove old gasket material. Apply a thin layer of assembly lubricant to the valve stems. After installation, torque the head bolts to the manufacturer’s specifications (typically 25–30 ft-lbs in a multi-step sequence). Allow the engine to idle for 10 minutes, then re-torque bolts after the first heat cycle. Check for coolant and oil leaks after initial startup.

In independent tests, it has demonstrated comparable service life (typically 3,000–5,000 hours under normal operating conditions). We offer a 12-month warranty against defects, providing peace of mind for commercial and industrial applications.
