Frequently Asked Questions
Q1: What is your main products?
A1: We are specialized in the excavator engine spare parts, for example Main cylinder block, cylinder head, crankshaft, Engine assembly, piston, cylinder liner, piston ring, camshaft, connecting rod, oil pump, water pump, valve series products, movement, etc. almost all parts of the entire engine.
Q2: Do you test all products before shipping?
A2: Yes, we conduct 100% testing before shipping.
Q3: Which engine models is this Alternator Pulley compatible with?
A3: This product is designed for specific diesel engine models. If you can provide the engine model or original part number, we can confirm compatibility before shipping to avoid incompatibility issues.
Q4: What are the symptoms of a damaged alternator pulley?
A4: If this pulley (321-6131) experiences groove wear, abnormal noise, or belt vibration, it will directly lead to insufficient alternator output power and accelerate the premature failure of the transmission system.
Q5: What is the function of an alternator pulley?
A5: The alternator pulley, by matching the speed ratio with the engine crankshaft, efficiently converts mechanical energy into electrical energy. Through its groove design or unidirectional drive mechanism, it ensures power stability and vibration damping of the transmission system at high speeds.
