Federal-Mogul Motorparts’ range will be extended to include replacement gaskets for popular commercial diesel engines used in mining, construction and other demanding applications, such as Caterpillar, Cummins and Detroit Diesel engines.
ML7 head gaskets are engineered and manufactured to withstand significantly higher combustion pressures and temperatures and to accommodate increased vertical and lateral motion between the engine block and cylinder head.
FP Diesel is a global brand of Federal-Mogul Motorparts, a global manufacturer and distributor of a broad portfolio of products in the global OEM and aftermarket vehicle sector, and a division of Federal-Mogul Holdings Corporation.
Now available for Caterpillar C15, Cummins ISL, QSL, ISX, QSX and M11, and Detroit Diesel 50 and 60 Series engines, FP Diesel ML7 head gaskets incorporate three solid steel cores sandwiched within an advanced graphite composite material.
The multiple layers are tied together through precisely engineered perforations in the graphite material and an intermediate, secondary sealing layer.
Each gasket’s steel core reinforcement helps ensure optimal compressed thickness for improved combustion, better fluid sealing capabilities and superior heat-resistance for high-output engines.
Federal-Mogul Motorparts’ engineers designed each gasket to achieve optimal load balance between all component materials, including the gasket body and combustion armour.
The wire used in the combustion armour is manufactured from copper flash-coated, low-carbon steel that better absorbs stress without cracking, compared to commonly used stainless steel wire.
Each gasket also features a proprietary moly coating to address the conformability demands of the variety of surface finishes found in the engine rebuild service environment.
This coating helps seal imperfections in the head and block mating surfaces and allows the gasket to adapt to controlled casting motion. It also ensures a no-stick release for future engine work.
“A gasket’s ability to accommodate rising pressures and temperatures, as well as increased casting motion, has become increasingly important as OEMs reduce overall engine mass and boost cylinder efficiency,” says Federal-Mogul Motorparts EMEA director of Off-Highway/Heavy Duty Frank Piojda.
“Commercial engine rebuilders look to Federal-Mogul and the FP Diesel brand for the latest and best engine sealing solutions,” Piojda adds.
The ML7 design helps the company’s customers maximise engine durability and productivity in an age when their equipment is being operated in extremely harsh conditions.
Federal-Mogul’s global network of research and development facilities contributed to the design of this innovative sealing solution.
The company’s dedicated aftermarket engineering group in Skokie, Illinois in the US has adapted the technology to the needs of FP Diesel customers.
