  • Weight: 17.00 lbs (7.73 kg)
  • Dimensions: 30.00 cm wide × 36.00 cm deep
  • Engine: Fits machines with the Cat 3046 engine
  • Type: Exhaust muffler
  • Condition: Aftermarket replacement part
  • Engine & Fitment Notes: Later 939/939C and the D5C III use the 3046 engine. Early 939 machines built with the 3204 engine can take a different muffler — confirm your engine model before ordering
  • Application: Reduces engine noise and routes exhaust gases away from the machine on the 939 and 939C track loaders and the D5C III dozer

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.
