Product FAQ

Inspect the mounting details and related hardware for wear or damage. Ensure the turbocharger housing is clean and the actuator shaft moves freely before installing the new unit.

Common symptoms include erratic boost pressure, stalling, or the turbo not spooling correctly. Check for physical play in the actuator arm or broken related hardware.

If the turbine or compressor wheels are damaged, or if the CHRA is worn beyond repair, replacing the complete turbocharger assembly is often more cost-effective than individual parts.

The application path lists Perkins 1104A as a reference application. Verify your specific engine serial number and turbo configuration to confirm fitment before ordering.
