Wear Plate Installation
1. Install the two cylinder o-rings.
2. Using silicon sealant, coat the circumference of the
concrete cylinders, the back of the wear plate and
around the five bolt holes. Next, install the wear plate
and the five bolts. The bolts must all be equally snugged
and tightened to 100 foot pounds each.
Wear Ring Installation
1. Install the wear ring into the nun plate.
2. Install the steel insert ring inside of the rubber energizer
ring.
3. Install the energizer ring assembly into the nun plate.
4. After installing the above mentioned components
