• Product Name: MLS Multi-Layer Steel Cylinder Head Gasket
• Structure: Multi-layer stainless steel laminated anti-burst structure
• Application: CAT 312D2, 313D2, 315C mini excavator; 416D/420F backhoe loader; AP300D asphalt paver, stationary generator set
• Material: High-strength stainless steel composite, resistant to high temperature, cylinder pressure, coolant and engine oil corrosion

1. Exact OEM stamping, fully matches all bolt holes, water jacket channels, oil return holes and intake/exhaust ports of CAT C4.4/3054 engine, direct bolt-on installation without modification.
2. MLS multi-layer metal structure greatly improves pressure resistance, effectively prevents gasket blowout, gas leakage, coolant and engine oil mixing emulsification under long-term heavy load construction operation.
3. Stable compression rebound performance, durable sealing in high-temperature and dusty working environment, reduces engine breakdown rate and maintenance cost.
4. Independent single component for complete C4.4 engine overhaul gasket kit, can be matched with valve stem seals, crankshaft front/rear oil seals and injector O-rings for full top-end rebuild.

This 258-4946 cylinder head gasket is the core sealing component installed between cylinder head and cylinder block for CAT 4-cylinder industrial diesel engine. It isolates four combustion chambers, cooling system and lubrication system to avoid cross leakage of high-pressure exhaust gas, antifreeze coolant and lubricating oil. It resolves typical engine faults including continuous overheating, power drop, white smoke exhaust, difficult cold start and oil dilution, and must be replaced during cylinder head disassembly and major overhaul.

We supply parts for Kubota, Cummi ns, CAT, Perkins, Yanmar, Isuzu, Komatsu, Mitsubishi, Hino, Nissan, Vol vo, Deutz, Doosan, Daewoo, John Dee re, Scania, Hyundai, JCB etc.

A: The interchange Perkins part number is 3681E051, both fit the same 1104 base engine platform.

A: Mainly for CAT 312D2, 313D2 excavators, 414E/416F backhoe loaders, AP-300D asphalt pavers, industrial generators and compact wheel loaders.

A: Persistent engine overheating, bubbles in radiator expansion tank, milky emulsified engine oil, white smoke from exhaust pipe, low cylinder compression, increased fuel consumption and hard cold ignition.

A: Recommended to replace full C4.4 overhaul gasket kit, valve stem oil seals, crankshaft front & rear oil seals, fuel injector sealing O-rings and new torque-spec cylinder head bolts synchronously.
