Unplug machine, Take off chip deflector, raise head, and remove pressure screws over swing arm.
Remove two 54-15 pivot screws and remove swing arm, leaving chain connected to mating sprocket.
Reinstall each pivot screw with a drop of medium strength thread locker.
Take the sprocket off the swing arm axle by putting the feed roller in a vise. Use a couple of small
adjustable wrenches attached to the flat on the long axle to loosen it.
Put a good square shank flat bladed screw driver into the slot on the short axle. Push in as hard as you can
while using a wrench on the square shank of the screw driver to loosen the short axle. Sometimes this axle
will not come out. Hack saw it off if it won’t. If you need to save the roller, pull the roller out of the swing
arm by lifting it up and pulling it out with the short axle still in the roller. Reset the roller in a vise and use a
small pipe wrench to remove it from the roller.
REASSEMBLY The rollers are constructed with a shallow hole in one end and a deeper hole in the other.
The P-122 post side axle always goes in the short end. Reinstall the P-122 axles with two drops of medium
strength thread locker on the thread portion. Do not use thread lock on P-124 or P-224.
The longer axle goes in the deeper end. See drawing for swing arm assembly with roller.
POSITION OF SPROCKETS First position feed motor shaft sprockets with hubs facing in toward chain guard..
The first sprocket slides up to the end of the flat on the motor shaft and the second right up against the first.
Chains should (under load) run in a straight line from these sprockets to the roller sprockets. Adjust the roller
sprockets to achieve this alignment. Feed roller sprockets should be positioned based on the feed motor
sprockets already positioned. The chains should run in a straight line from the feed motor sprockets to the roller
sprockets when the machine is under load.
