As I posted earlier, I got the A2 running now, and most of the machine working.  The problem I have run into is that the raddle slip clutch slips/chatters terribly.  It looks like the raddle is froze up.  I have pulled all of the access doors off trying to get to it.  Is there any good way to work on it.  I have almost come to the conclusion that I am going to have to remove the header throat this summer to get to it.  Any suggestions?

Thanks
Adam

You can take the side covers off, the lower cover off at the front (make sure the idlers aren't worn or messed up causing chain to bind), also make sure the raddle isn't slacked and hung up.  I have had three or four times where I had a stone or twig get under the back sprockets not allowing the raddle to turn and slipping the clutch.  I guess I would start soaking it down and see what happens.  That have wood slats on the raddle?

Nick is right on about the raddle!
You might look at the sheet metal end rolls, I had a corner of mine turn up and grab the wood shat and stopped it dead in it's tracks. You might try turning it back a little.
DO NOT put a grease gun on a slip clutch.

possible problems from easiest to worst:
 
1. Worn raddle slip clutch.  check its spring, roll pin, & teeth for wear.
 
2. Look for any place that the chain is catching - front idler debris, cracked or bent raddle floor, worn chain, jumped chain that is out of timing, improper raddle chain tension, and/or worn drive sprockets. 
 
3. A twisted rattle drive shaft located just left of the right hand drive sprocket can put it out of time for both of drive sprockets.  Do a visual check on drive sprockets thru access panels to confirm that drive sprockets are in time.
 
general info:  front idlers will rust up and not rotate.  Raddle Chain tension - at middle access door a proper chain tension should allow about 1.75"-2" up from the floor.  If the chain has stretched you may remove links either down in front near the idlers or sometimes its easier to remove them at mid-point access panesl.  For idlers & chain tension, check them at the beginning of each season and 1/2 way thru the season.
To disassemble rattle for serious repairs try removing the walkers and accessing it from the rear of the combine.  Usually at this time, the drive sprockets are also worn so that shaft & bearings is also removed.  If you have to replace a floor, you will need to make some type of a inside spreader mechanism to help achieve allowable clearance for remove & installation.  If you decide to remove the cylinder throat at the pivot you will need some type of a hoist or loader boom and it is much more involved with return elevator, drive belts, hydraulics, & it is heavy.  I have removed the raddle chain from the front without removing the throat, but it takes two people & installation takes a rope to help pull it back up into the floor.  Only remove the raddle if it is totally worn out and needs replaced.  You can make most repairs to it while it is in the machine via the mid access panels or down in front at idlers. 
Maintenance schedule should include that you remove the front raddle cover under the cylinder throat at the end of each season & clean out all debris & seed.  This decreases rust opportunity & removes mouse food.  It also gives you another look at the chain & idlers.
