C18 Exhaust Sleeve Assembly 194-8124 For CAT C18 Diesel Engine

• Product Name: Engine Exhaust Sleeve Assembly / Exhaust Manifold Outlet Pipe
• OEM Part Number: 194-8124 (Alternative: 281-8261, 266-2778)
• Specification Code: C18
• Compatible Engine: CAT C18, also interchangeable for CAT C15 engine
• Set Quantity: 6 pieces per full engine set (matches 6 cylinders)
• Structure: Welded steel exhaust pipe + integrated high-temperature resistant graphite flange gasket with fixed copper rivets
• Material: High-strength seamless steel tube with high-temperature black anti-rust coating; flange adopts reinforced graphite composite gasket
• Core Features
  1. Integrated flange gasket eliminates separate gasket installation, avoids exhaust gas leakage
  2. High temperature and oxidation resistant steel body, withstands long-term high-temperature exhaust impact
  3. Precisely drilled mounting holes for direct bolt-on installation without modification
  4. Effectively seal exhaust passage, prevent toxic gas leakage and engine power loss
• Application: Exhaust system replacement spare part for CAT C18 engine, widely used in CAT mining trucks, heavy excavators, generator sets, marine propulsion engines and industrial power equipment

This 194-8124 exhaust sleeve assembly is a dedicated exhaust outlet component for CAT C18 six-cylinder heavy-duty diesel engine. One complete engine requires 6 individual sleeves to correspond to each cylinder exhaust port.

The product integrates the steel exhaust connecting pipe and high-temperature graphite flange gasket into one assembly. The riveted fixed gasket will not fall off during installation and disassembly, greatly improving construction efficiency and long-term sealing reliability. The outer black heat-resistant coating effectively slows down rust and high-temperature aging under harsh working environments.
It is a necessary replacement part during engine top overhaul, exhaust manifold disassembly or solving exhaust backpressure increase, exhaust leakage, abnormal noise and power drop faults caused by cracked old sleeves and failed gaskets.

We supply parts for Kubota, Cumm ins, CAT, Perkins, Yanmar, Isuzu, Komatsu, Mitsubishi, Hino, Nissan, Vol vo, Deutz, Doosan, Daewoo, John Dee re, Scania, Hyundai, JCB etc.
Shipping: Sea freight, air freight and international express are all available. Goods will be arranged for shipment promptly after payment confirmation.
Tax Notice: All import duties and local destination taxes shall be borne by the buyer. Please verify local customs regulations in advance.

Q: How many pieces are needed for one CAT C18 engine?
A: 6 pieces in total, one exhaust sleeve for each of the 6 cylinders.

Q: Can this 194-8124 sleeve fit CAT C15 engine?
A: Yes, it has universal compatibility for both CAT C15 and C18 series engines.

Q: What faults will damaged exhaust sleeves lead to?
A: Exhaust gas leakage, loud exhaust abnormal noise, increased engine backpressure, reduced output power, excessive fuel consumption and overheating.

Q: Is the flange gasket replaceable separately?
A: The gasket is riveted integrally, we recommend replacing the whole sleeve assembly for optimal sealing performance.
