Dimension Table Outside Radius X Z 4" - 6" 7w" 11" 7" - 9" 62" 11" 10" - 12" 5" 11" 13" - 15" 42" 11" 16" - 19" 32" 11" 20" - 22" 3" 11" 23" and Larger 2w" 11" Step Two: Layout From the center of the pulley shaft, scribe an arc (equal to your "Y" dimension) on the outside of the mounting structure wall. Then measure down from the center of the pulley shaft using the "Z" dimension, and using a level, scribe a horizontal line across the mounting structure that intersects the arc at "Y". Using a level and scribe, draw a vertical line approximately 8" long which bisects the horizontal line at the intersection. This bisected point will be the center point for the mounting spool location. If no structure is available at this point, metal will need to be added. Step One: Calculations Measure the distance from the center of your pulley shaft to the outside surface of your conveyor belt. This will be your Outside Radius ("A" on the illustration below). Find your Outside Radius on the Dimension Table to the left. Add the corresponding "X" dimension to your Outside Radius. (Example: 14" Radius + 412" = 182"). This is your "Y" dimension (Y = 1812"). The illustrated "Z" dimension is a minimum value and provides for the optimum mounting position. V-Grooves The Eraser HD System comes fully assembled. Remove the mounting spools from the system. The mounting spools are designed to be welded or bolted into position. Using a mounting spool as a template, line up the centering V-grooves machined into the flange of the mounting spool with the bisected horizontal and vertical lines on the mounting structure wall. Trace the inside diameter of the spool and the entire perimeter of the square flange to the mounting structure wall. Also, transfer the bolt hole pattern if you intend to bolt the system into place rather than weld. Repeat this Step Two process for the other side of the mounting structure. Page 7
Step Three: Mounting Cut the center hole with approximately a s" larger radius than the trace which was scribed on each side of the mounting structures (your hole should be approx. 32î in diameter). NOTE: For Bolt In Only - Using the traces that you scribed for the mounting holes, drill four m" diameter holes to accept w" diameter grade 8 bolts. Place the mounting spool onto the side of the mounting structure wall. Use the scribed perimeter lines to line up the spool and then weld or bolt it into place. If welding, four stitch welds is sufficient on the flats of the mounting spool. Using a 2" end wrench, loosen the (3) square head set screws at each end of the mainframe. Remove the stub end pipes (and tensioner assembly) from the mainframe. Loosen the locking collar set screw and collapse unit as fully as possible. Lift the mainframe into position. Telescope the stub ends and slide tensioner assembly through the holes in the mounting structure. Temporarily install tension pin through mounting spool. Center the blade with the belt and snug the mainframe set screws to secure the stub ends. Snug locking collars to inside wall and cinch the set screw. Check for free rotation, minimal lateral movement of the assembly shaft, and consistent contact of the blade to the belt. Adjust if necessary, realign, and tighten all mainframe set screws. WARNING When tensioning be sure to keep body clear of the tensioner path. Step Four: Tensioning The ERASER HD System is provided with our exclusive internal Perma-Torque Tensioner. The Perma-Torque is an adjustable elastomeric tensioner. The tensioner may be adjusted from a recommended minimum of 25 foot pounds of force to a maximum 80 foot pounds. Exceeding tensioning of 14 holes or 504 will damage the tensioner. Five holes or 180 is our standard, which is recommended for most applications. To tension, first remove the tensioning pin, then use a 14" end wrench on the exposed hex bar and turn the tensioner towards the pulley. When you have reached the desired rating, replace the tensioning pin. The s" diameter hole in the hex bar will be in line with the holes in the mounting spool and the hole in the tensioner. This helps to align the tensioning pin. You may optionally choose to use a crescent wrench, pipe wrench, large screwdriver or pry bar in place of the 14" end wrench.

Installation is now complete. Maintenance or retensioning should not be required throughout the life of the blade. Page 8
