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

The first sign of a failing exhaust extension is often an audible increase in exhaust noise or the presence of exhaust fumes in the operator's cabin. If not addressed, leaks can worsen, leading to reduced engine performance due to backpressure issues and potential damage to nearby components from hot exhaust gases. Ignoring a significant exhaust leak can compromise engine efficiency and create a hazardous working environment.

Installation Tip

Ensure that all old gasket material is completely removed from the mating surfaces before installing the new extension. Do not reuse old clamps or fasteners, as they may not provide a secure seal.

Service Note

Inspect the exhaust manifold and turbocharger outlet flange for cracks or warping, and check the condition of any flexible exhaust bellows.
