F2 sickle drive bearing

johnea4 · Oct 29, 2013

Have an F2 with a 13" head, floating cutter bar and wobble box. I replaced all the sickle sections a couple of weeks ago, but didn"t pay enough attention to how the sickle drive was bolted to the wobble box drive. I put it back the way i thought it was with spacers, washers, etc., but everytime i checked it it seemed loose and obvioujsly had a lot of slop, much more than before (i"ve had it 6 years and never had any trouble with the drive.) I tightened it each time (the bolt was double nutted on top) assuming the spacers would allow the bearing to work. Then after about 30 acres the bearing went out today. I haven"t had a chance to look real close, is this a removable bearing, any idea what number? And can someone tell me how to connect it back to the wobble box drive correctly? Thanks!

The bearing in the drive arm is removable, I have no idea on the number. I believe there are multiple washers/shims used between the drive arm and the sickle head, to take up the slack so the head is in line with the sickle.

Mine is over an hour away, or I would go look.

Little off topic, but does anyone use the poly Shoup sells to be riveted on the skid plates under the H-C bar? We haven't gotten all the soybeans out and it has rained and thought the poly would help in getting thru the field.

Okay i found a parts diagram that's close, found the bearings at Shoups (just have to figure out if mine should have the single bearing or the pair.) So when bolted up properly the bolt should be very tight to hold the wobble box tight against the bearing basically and not the drive head, correct? the top surface of the wobble box at the bolt hole is wallowed out, indicating this has happened before. Should i replace that whole piece or try to shim it up?
