(2) 2.717" Stainless Steel Boat Trailer Bearing Buddy w/ Protective Bra

Description: This is Trailer Bearing Buddys part number 2717. This is a great trailer bearing buddy to use in salt water since it is stainless steel and therefore will not rust. This trailer bearing buddy measures 2.717 inches at its base. It is designed to be used in most 8 bolt hubs. Trailer 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. Trailer Bearing Buddy's help keep dirt and water out of your hubs and bearings. HOW TRAILER BEARING BUDDY WORKSThe axle hub is filled with grease until the grease forces the Trailer 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. Trailer Bearing Buddy will last the life of your trailer. The outer barrel is made of stainless steel. Internal Trailer Bearing Buddy parts are also made of stainless steel for maximum corrosion protection. HOW TO INSTALL A TRAILER BEARING BUDDYBEARING AND SEAL INSPECTIONRemove hubs and check the bearings before installing Trailer 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. TRAILER BEARING BUDDY INSTALLATIONHold the Trailer Bearing Buddy against the hub with a small block of wood, and drive it into place with a hammer. If the Trailer 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 Trailer Bearing Buddy is obviously too large or too small; contact your dealer. HOW TO REMOVE A TRAILER BEARING BUDDYTrailer Bearing Buddy is held in the hub by an interference fit. To remove a Trailer 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 Trailer Bearing Buddy out of the hub. Dont disassemble the Bearing Buddy to attempt to remove it. eBay item #350502648565
