Product Introduction C4327413 Turbocharger Bolt is a high-temperature fastening fastener used for fixing turbocharger on Cum-mins ISZ13 diesel engine. It locks the turbo assembly to exhaust manifold, ensuring stable connection and sealing under high exhaust temperature and engine vibration. This aftermarket replacement bolt solves bolt elongation, thread sliding and fracture risk caused by long-term thermal cycling and heavy load fatigue of original bolts, preventing exhaust gas leakage and turbo loose shaking for long-distance heavy cargo transport vehicles.

Product Advantages Made of high-temperature alloy steel and processed by special heat treatment, with excellent tensile strength and fatigue resistance. Precision rolling thread ensures uniform stress distribution and anti-loosening performance. Surface oxidation treatment prevents high-temperature oxidation and corrosion. Each bolt undergoes mechanical sampling testing before shipment, stable clamping force and reliable fixing performance for turbocharger assembly.

Applicable Models Fit for heavy-duty trucks equipped with Cum-mins ISZ13 diesel engine, widely used for highway long-haul logistics and bulk cargo transportation.

FAQ

Q1: What problems will broken turbo bolt cause?
A1: Exhaust gas leakage, abnormal exhaust noise, turbo shaking and risk of gasket burning out.
Q2: Should I replace turbo bolts in sets during maintenance?
A2: Yes, it is recommended to replace all bolts together when disassembling turbo assembly.
Q3: What torque standard should be followed during installation?
A3: Install according to OEM torque specification; over-tightening will lead to bolt fracture.
Q4: Why turbo bolts are easy to fatigue?
A4: Repeated drastic temperature changes and continuous engine vibration bring cyclic stress.
