Turbocharger for Loaders, 6677575

Turbocharger for Loaders, 6677575 designed for Engine 526323 & Above. 

Bobcat turbochargers force air into the cylinders, helping the engine produce more power. The air is filtered through the pipes and components of the turbocharger, giving you quieter and smoother engine noise.

There are three main failure modes for turbochargers:

Turbo shaft fault

  • Potential Causes: poor lubrication, foreign material from intake air, defective shaft/bearing, oil leak from shaft bearing
  • Symptoms: No engine power, fluctuating rpm, hard starting, black smoke, noise from turbo

Poor/faulty waste-gate actuator (stuck wastegate, broken wastegate linkage)

  • Potential Causes: Foreign material from intake air, abnormal blow-by-gas, defective actuator
  • Symptoms: No engine power, fluctuating rpm, black smoke, emission control fail

Intake air/exhaust gas leaking

  • Potential Causes: Damaged hoses & clamps, faulty gaskets, faulty turbo shaft bearing/seal
  • Symptoms: No engine power, fluctuating rpm, black smoke, emission control fail, noise of air/gas leaking
When replacing a turbocharger always prime the turbo with clean engine oil and rotate by hand prior to completing installation.

Also available as a Remanufactured Turbocharger, 6677575REM

Due to engineering standards, some parts are updated or changed and are assigned a new part number. Previous part number was 6673173 for Engine 526322 & Below. This part is the replacement. You will also need 2 bolts: 6677578, gasket: 6677577, and flange: 6677576

If you have a replacement engine 6686497 or 6686497REM, you will need Turbocharger: 6690633 or 6690633REM
