(4) 1.98 Stainless Steel Boat Trailer Bearing Buddy w/ Protective Grease Bra

Description: This is part number 1980-SS. This is a great bearing buddy to use in salt water since it is stainless steel and therefore will not rust. This bearing buddy measures 1.980 inches at its base. It is designed to be used in most 4 and 5 bolt hubs. Bearing buddys put a small amount internal pressure in the hub (about 3psi). When the hub is submerged water cannot enter the hub because of this pressure. Its a great way to extend bearing life and service your bearings in-between hub re-packs. Bearing Buddy's help keep dirt and water out of your hubs and bearings. The blue indicator ring will protrude out to let you know when your bearing buddy is full, or sink back in to let you know that you need to add grease. HOW BEARING BUDDYS WORKSThe axle hub is filled with grease until the grease forces the Bearing Buddy piston outward about 1/8 inch. Because the piston is spring loaded, the piston exerts a slight (3 psi) pressure against the grease, which maintains a slight pressure between the inside of the hub and the outside environment. When the hub is submerged, water cannot enter the hub because of this pressure. An automatic pressure relief feature prevents over-filling and over pressurization. Without this feature, the inner seal will be damaged. Grease can be added to the hub through an easily accessible grease fitting located in the center of the piston. Lubricant level (and pressure) can be checked quickly by pressing on the edge of the moveable piston.If you can rock or move the piston, the hub is properly filled. Bearing Buddy will last the life of your trailer. The outer barrel is made of stainless steel. Internal Bearing Buddy parts are also made of stainless steel for maximum corrosion protection. HOW TO INSTALL A BEARING BUDDY BEARING AND SEAL INSPECTIONRemove hubs and check the bearings before installing Bearing Buddy. Replace bearings if they are damaged, rusted, or pitted. Clean old grease and contaminants out of the hubs. Check the condition of the inner seals. Be sure they are new, top quality, and running on a smooth spindle sealing surface. IMPORTANT: As you reassemble the components, fill the hubs completely with a high quality, multipurpose, no.2 grade lubricant (e.g., the type used for automotive suspensions). Don't use heavy, fibrous greases; don't mix grease types. BEARING BUDDY INSTALLATIONHold the Bearing Buddy against the hub with a small block of wood, and drive it into place with a hammer. If Bearing Buddy cannot be driven into the hub, or will not fit tightly into the hub, don't force it. Your hubs may be slightly oversized or undersized. If this occurs, or if the Bearing Buddy is obviously too large or too small; contact your dealer. HOW TO REMOVE A BEARING BUDDYBearing Buddy is held in the hub by an interference fit. To remove Bearing Buddy, lay a block of wood against the side of it and strike the wood with a hammer. Place the wood on the opposite side and hit again. Continue this procedure until you walk the Bearing Buddy out of the hub. Dont disassemble the Bearing Buddy to attempt to remove it. eBay item #266145129065
