AGCO - 4305912M1 - Massey Ferguson 3386895M2 Sealing Ring

This sealing ring sits in the front axle housing of the host tractor, creating a static seal between two mating faces to prevent lubricant leakage and keep contaminants out of the axle assembly. It is a flat gasket, not a dynamic seal, so it relies on uniform compression from the bolted joint to maintain its seal. A degraded or missing ring allows axle oil to weep past the joint, which can lead to reduced lubricant level and accelerated wear on the differential and final-drive components. The part is manufactured to the original geometry so that it matches the groove depth and bolt pattern of the housing without requiring additional shimming or sealant. On reinstallation, clean both mating surfaces and tighten the housing bolts to the specified torque in the correct sequence.
