PRESS TOOL FOR COUPLER PIN REMOVAL
CAUTION! Always wear proper safety equipment and take caution with
tapered pin when attempting to remove. The use of this tool will assist in
the removal of tapered pin in feedwheel coupler. Lubricate end of bolt and
threads with grease. Position the press tool so that it cradles the coupler,
with the large end of the tapered pin at the side opposite the press bolt. You may want to remove yoke springs
to get easier access to coupler. Set the tool as described and hand tighten press bolt to snug tool against
coupler. Make sure press bolt is set on small end of tapered pin, and that pin will go thru hole in tool without
interference. Use of a 1/2” impact wrench is recommended. Run impact on bolt to start pin removal, then
usually a good hit with hammer on the end of bolt will knock out the pin. You may have to run impact on bolt and
hit with hammer a few times to remove pin.
