FAQ

Q1: How do I confirm this glow plug fits my Yanmar 4TNE84 engine?

Check your existing glow plug for the part number 129155-77800 or 129155-77801. Alternatively, verify your engine model number on the engine nameplate. This part is a direct OE replacement and requires no modifications.

Q2: What is the recommended installation procedure?

Disconnect the battery negative terminal. Remove the electrical connector from the old glow plug, then unscrew it using a 10mm deep socket. Apply anti-seize compound to the threads of the new plug, torque to 15-20 Nm, and reconnect the wiring. Reconnect the battery and test for proper heating.

Q3: How often should I replace glow plugs on my Yanmar 4TNE84?

Glow plugs typically last 80,000-100,000 hours of engine operation. Replace them if you notice hard starting, white smoke on cold start, or if the “wait to start” light stays on longer than usual. It is recommended to replace all glow plugs as a set for balanced performance.
