I just bought and am rebuilding a JD 7000 planter-first time I have ever done a complete planter teardown/rebuild.I am sure I will have some more questions as I get into it-but I have a couple initial questions. 1) 3 of the 4 drive sprockets (on the drive wheels)-seem very loose. The wheel bearings seem ok but just a LOT of space and play between hub and sprocket-probably 1/4-1/3 inch. Are there some spacers I can put there or is there something else I am overlooking? 2) The bearing at the top side of the transmission has been out for some time. I guess the previous owner just ran it that way. Do I have to remove the whole shaft along the entire left side of the planter to replace that? 3) All of the disc openers are about 14 1/2 to 14 1/2-so while I got it all apart I am going to replace those. Sloans Express has the complete disc for $17, or Heavy Duty ones for only $3 more each-3.5MM. If I go with the heavier ones is there anything different (other than shims) to get that set up right. Different scraper or anything? I am going to set this planter up for no-till after I get the basics so I was thinking the HD may be better. 4) John Deere has a kit to convert the closing wheels from the old roll pin attachment to the new bolt on type. Does anyone know if that also gives you the lever to adjust the pressure on those wheels-and if that includes that cast block that the closing wheel sprint attaches to or does it use the one already on the planter? Any input would be greatly appreciated. Also any other advice on rebuilding that machine from someone who has done it would be great. Thanks!
