    When removing keyarms from a total adder style mech. Do not let the key coupler fall down with the keyarms out. This can cause the mech to fall out of time. I use this spring to keep the key coupler up all the time while the arms are out preventing the timing problem.

    I had a real long twisted wire like they use on a bread bag & other wires. When I start I have all of the counters out, the indicators & guides out, neck ties , the front cast iron bar that holds the drawer mech & the one going to the back( this removes the spring that pull the key coupler back). I take a big screw driver & put it in the opening of the coupler & press down (simulates a key being pressed). & fish my wire under the coupler & around the back frame & twist it to keep it tied up. Mache sure the projection on the right side of the coupler is in notch of the cam line. Now turn the machine on it's back & gently drive out the shaft for the key arms. Lubricate well as they want to follow the shaft. When an arm is free from the shaft let it come forward till it is straight & twist it 905 & pull it out. Stamp each key arm with the amount so you don't get it mixed up. They are stamped #1 thru #9 & might seem to be the same but some are cut outs for parts that need clearance. Never take the wire off until you get the keys back in. The key coupler will fall down one extra notch without the key arms in & the cam line will jump time. If you look on the cam line & find the notch the pointed arm from the coupler you can tell if its out of time. I don't take the cam line out to retime it. There is a small right angle guide that the revolution rick rides on & it is screwed to the out side of the side frame(sometimes one screw & a set pin). You can pry it off & move the coupler up & down by holding the anti back up pawl out.. Move the revolution rack up & back whine turning the cam line. You get a half tooth movement when you move it to the back & another half when you move it the front. Figure out which way you need to go? Then tie the coupler in place & replace he guide. If you take the #2 lock out be sure to put it back in before you put the key arms back in. It can be put in with the keys in but you need a long screw driver and grind the blade at an angel. Wiggle the lock in & put the top screw in the press the key arm next to it & get the bottom one in. Best to remember.
    I do have a DVD set showing this.

    Todd,

    Probably a dumb question, but how would I know if the timing is off? I am working on a Model 310 now and took all the key arms out and let the bale drop. If I just lift the bale with my hand or screwdriver, it seems to operate as normal. It goes up, jumps the small angled piece and goes back down to complete the cycle. Do I need to fix something before I put the key arms back on?

    Thanks!

    Blake

    If you can cycle the mech, it is not out of time. If it were out of time the key coupler (or bale) would go up, but not back down.

  • Excellent advice. I would suggest going one step further and having a first time pick up a cheap 700 series slicker and do a dry run experiment so they can build up some confidence and skill.

    Attached are pictures of the cycle. Key coupler and cam timing. This is from a working machine in the correct timing.
    The red dots are the timing points.

    This picture is in the home position of the key coupler and cam.
