Nordlock Washers
Nordlock-style lock washers are used in many places on this machine. These twopiece washers have
a ramped surface in the center and a splined outer surface. Since the angle of the ramps is larger
than the angle of a bolt’s thread, and since the splined surfaces grip the material around them, these
washers provide excellent bolt-holding capabilities.
Nordlock-style washers must be used anywhere they were originally installed on this machine. Take
care during disassembly to collect both parts of each washer for later reuse.
During installation, be sure to assemble the pairs as shown, with the ramped surface in the middle
and the radial splines facing out.
