FAQ ：
Q1: How to check if it fits my engine?
A1: The most reliable way is to check your engine model (located on the cylinder block) and match it to the applicable list of this housing. You can also measure the inner hole size and bolt spacing of your old housing-if they match the 612600011088 specifications, it will fit.
Q2: Why does the engine make abnormal noise after installation?
A2: First, check if the housing bolts are tightened to the correct torque (usually 80-100N·m). If bolts are properly tightened, use a dial indicator to inspect the inner bore alignment-if the error exceeds 0.05mm, the housing may be defective. If alignment is correct, check for loose clutch or starter components and reattach them securely.
Q3: How to maintain the flywheel housing?
A3: Tighten mounting bolts every 30,000km, clean oil and dust buildup regularly, and replace worn or leaking gaskets promptly.
Q4: Should I replace the sealing gasket during installation?
A4: Yes-old gaskets are prone to leakage. Use an original replacement gasket and apply high-temperature sealant if necessary.
