Description
The Hustler OEM 607478 Grease Relief Fitting is an expertly designed and integral part of the Hustler Greaseable Spindle Assembly. It effectively prevents over-greasing and ensures that your Spindle Assemblies are fully greased. With the Hustler 607478 Relief Valve, grease pressure is released from the side of the Spindle Assembly, preventing the buildup of pressure that can damage the outside seal of your sealed roller bearings. This also prevents dirt and debris from entering the roller bearing balls, ensuring smooth and efficient operation. The Hustler OEM 607478 Pressure relief Valve is used with the Hustler Commercial Spindle Assemblies 607407P & 607408P that are used on the Hustler Commercial X-ONE, X-RIDE, Super Z, Super Z HD, Diesel Z, Super S, Super 104, Super SF and Super 88 Series Mower Decks.
