• Application: Reduces engine noise and routes exhaust gases away from the machine on the 966G and 972G wheel loaders

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.
