For Roller Replacement
(A plastic roller bracket assembly is supplied with units ranging from 2 to 108 RPM. No assembly is required for the plastic bracket. If new rollers are required a new assembly must be ordered).
1.To remove the roller bracket assembly from the pump, use a flat head screwdriver and pry open both sides of the springs to the edge of the bracket.
2.Pull the roller bracket assembly off the shaft holding on to the roller area of the bracket.
3.Holding the top and bottom of the bracket, slide the spring off to the side and lay the assembly on a flat surface. Try not to let it fall apart as you will need to put it together the same way it is now.
4.Remove the top bracket and the rollers.
5.If a roller pin comes out of its recess, replace it at this time.
6.Place the new rollers on the pins and replace the top bracket. Be sure that the flat in the inner hole of the top bracket lines up with the flat on the bottom bracket.
7.Slide the spring fastener back over the bracket. Do not snap the spring together.
8.Matching the roller bracket flat to the output shaft flat, slide the roller bracket assembly down until it stops without using force.
9.Snap the spring together.
