Part Numbers: 1172362, 117-2362, 5I9076, 0969205, 7I8874
Weight: 18.30 lbs (8.30 kg)
Dimensions: 24.00 cm wide × 68.00 cm deep
Engine: Fits machines with the Mitsubishi 4D31 / 4D32 engine
Type: Exhaust muffler / silencer body (not a complete exhaust pipe kit)
Condition: Aftermarket replacement part
Engine & Fitment Notes: Fits the original 307 (307-A) and its predecessor E70B. The later 307B and 307C use a different engine and exhaust and are not covered — confirm your machine is an original 307 or E70B before ordering
Application: Reduces engine noise and routes exhaust gases away from the machine on the original 307 and E70B mini excavators
Common Use Case or Symptoms: Use when the muffler is rusted through, leaking exhaust, excessively loud, or physically damaged — a failed muffler allows exhaust gases and noise to escape at the machine rather than being routed away safely.
Why Choose Broken Tractor: ✅ Correct Fit for the Original 307 and E70B — matched to the Mitsubishi 4D31/4D32 engine exhaust ✅ Direct-Fit Silencer Body — ready to install in place of the worn original ✅ Fast Shipping from a U.S.-Based Team — ready to ship from our U.S. warehouses
