Corteco 3429791M1 Cassette Seal Assembly

The 3429791M1 is a RWDR Cassette-2 type wheel hub seal engineered for Mechanical Front Wheel Drive (MFWD) front axle applications. It incorporates a Simmerring sealing element with an optimized wear sleeve, designed to withstand demanding agricultural operating conditions including high shaft speeds and variable oil temperatures. Constructed with a metal outer casing and spring-loaded sealing lip, the unit utilizes NBR (Nitrile Butadiene Rubber) or ACM (Polyacrylate) compounds for compatibility with mineral oils and resistance to thermal aging. The seal assembly functions as a combined radial shaft seal and wear sleeve, eliminating the need for separate shaft machining or sleeve installation. Primary application covers Massey Ferguson tractor series including 261, 300, 3000, and 3600 series equipped with Dana/Spicer front axles. Cross-references include Massey Ferguson OEM numbers 3015376X1, 3426809M1, 3429004X1, and 3716210M1, as well as New Holland 87309584 and Landini equivalents. Manufactured to OEM specifications by Corteco (Freudenberg Group) under part number 12015133B, ensuring dimensional interchangeability and performance parity with original equipment.
