JD 567 Baler

I've been working on a used baler I bought and noticed that some of the sprockets have room to move on the shaft because they aren't shimmed tight. This isn't normal is it? Also, my partner uses bar and chain oil to lube chains. Do you think this is sufficient? Thanks!
 

I've custom baled hay with JD rd balers for 30 yrs that utilized the sprockets with hex bores on hex shafts. I've never experienced a problem with sprockets getting too loose on the hex shafts. Previous baler had 30,000 bales on monitor & present has 23,000+ bales on monitor. I lube my baler chains with aerosol chain lube
 
Jim, What I am seeing is the hex shaft sprockets have shims on each side to tighten sprocket in place on shaft I assume. I noticed on a couple of sprockets I could actually slide them a little on the shaft and the shims are loose. Thinking I need to add shims to keep sprockets correctly positioned.
 
Your worrying about nothing. The chain will align itself. The sprocket will wear out long before the hex would. My Current JD 566 just turned over 55,000 bales. The "NEW" JD 567 has over 35K on it and the real new JD 569 just passed 20K for bales. So I have seen a fair amount of baler usage. Keep the belts sized an lube the chains and you will be good to go.
 
Wasn't worried about the shaft so much as the chains and sprockets. I replaced the auger bearings and when I went back in with it, my sprocket at slip clutch was out of line with the other sprocket. It was tight on the shaft, but not because of shims. I was able to get it loose and see I can adjust shims to make it line up. On the other left side of baler I noticed sprockets that could slide on shaft that were not tightened with shims and wondered if it was required. Thanks for all the info!
