John Deere L227155 MFWD Axle Shaft Seal

The John Deere L227155 is a radial lip seal engineered for the Mechanical Front Wheel Drive (MFWD) axle shaft assembly. It functions as a dynamic sealing element to retain lubricating oil and exclude external contaminants such as dust, water, and abrasive particles from the axle housing. Designed to OEM specifications, this seal ensures precise fitment on the axle shaft journal, maintaining sealing integrity under rotational speeds and thermal cycles typical of agricultural tractor operations. It is a critical component for maintaining axle bearing life and preventing differential oil loss. Porter applications include John Deere tractors equipped with 4045 PowerTech engines, specifically models 6105J, 6415, 6425, 6M 110, and 6120R. Direct OEM replacement for part number L227155.
