1411480 Extension Gp-Exhaust — Cat 120H 120M 2

This exhaust extension assembly is designed to connect the exhaust manifold or turbocharger outlet to the main exhaust pipe or muffler system, ensuring proper routing of exhaust gases. Manufactured to withstand high temperatures and corrosive exhaust environments, it offers superior longevity over a corroded or cracked original part. Operators may notice increased exhaust noise, a burning smell, or visible exhaust leaks near the connection point if this component fails.

Installation & Application Notes

Allow turbo to idle 2–3 minutes before shutdown — this circulates oil through bearings and prevents coking. Check oil feed and drain lines for blockages before fitting new turbo. Replace oil and filter when fitting new turbo — old oil contains metal particles.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

An audible increase in exhaust noise, often described as a loud leak or roar, is typically the first sign of a failing exhaust extension. If left unaddressed, the leak can worsen, potentially allowing harmful exhaust fumes to enter the operator's cabin. Continued operation with a compromised exhaust extension can lead to reduced engine efficiency and increased emissions.

Installation Tip

Ensure the mating surfaces of the turbocharger/manifold and the next exhaust component are perfectly clean and flat before installing the new extension. Do not overtighten the fasteners, as this can damage the flanges or the new gasket.

Service Note

During replacement, inspect the turbocharger, exhaust manifold, and muffler for any signs of cracking, corrosion, or excessive heat damage.
