RPB-E Installation Guide
The following is a description of the installation procedures associated with the RPB Type-E. Installation instructions are included with each unit and should be followed closely.
- Prepare the rudder tube for bonding by wiping the inside clean of any dust or construction debris.
- Using a medium bodied epoxy or Chockfast®, coat the outside of the bearing unit that will be pressed into the tube.
- Lay a bead of marine sealant (such as Lifecaulk or 3-M 101) under the flange.
- Insert the unit into the tube.
- Temporary support may be required to keep the unit in position. Install rudder or dummy shaft to insure good bearing alignment until cured.
|
Note: Before installing the rudder, insert the red installation hat into the lip seal. When rudder is in place, remove, invert and replace it on top of the Type-E unit to keep debris off the lip seal during use. |
