Key Notes:

• Part Numbers: MIU800816
• Interchange Number: 129008-77800 (Yanmar)
• Voltage: 12V
• Sold: Individually — one glow plug per cylinder; 3-cylinder engines require three, 4-cylinder engines require four. Replace all glow plugs at the same time for consistent cold-start performance.
• Engine: Yanmar 3TNV88 (3-cylinder) and Yanmar 4TNV88 (4-cylinder) as fitted to applicable John Deere equipment
• Application: Glow plug — heats the combustion chamber of each cylinder prior to cranking to facilitate cold-weather starting on applicable John Deere compact excavators and skid steer loaders equipped with Yanmar diesel engines
• Condition: Aftermarket replacement part

Common Use Case or Symptoms: Use when cold-start performance has degraded, the engine cranks but fails to start in cool or cold temperatures, white smoke is excessive on cold startup, or when individual glow plugs test open or out of resistance specification — failed glow plugs significantly impair cold-weather starting on applicable Yanmar-powered John Deere equipment.

Why Choose Broken Tractor:

• ✅ Yanmar OEM Cross-Reference Confirmed: MIU800816 interchanges with Yanmar 129008-77800 — confirmed for the 3TNV88 and 4TNV88 engines fitted to applicable John Deere compact excavators and skid steer loaders.
• ✅ Replace as a Set: Glow plugs wear at similar rates and are inexpensive relative to labor — replacing all plugs at once ensures consistent cold-start performance and avoids a second service visit shortly after the first.
• ✅ Fast Shipping from a U.S.-Based Team: In-stock and ready to ship from our U.S. warehouses.
