Using a 10MM open end wrench, remove every-other sucker tube at either side of center tube for a total of six tubes.
Thread the Sucker tube Spacers onto the threaded end of each sucker tube using a pair of pliers to gently grip the spacers at edges.
'Do Not' attempt to grip and thread Spacers onto sucker tubes with your bare fingers! The thin (only .017" thick) spacers can act as a rotary knife and easily cut your fingers!
Re-install suckertubes and re-tighten them and you are ready to begin feeding troublesome stocks more effectively at higher production speeds.
