have to replace feeder chain on jd 9600.is there any difference between Harvest and Gibson feeder chains?anybody had any problems with them jumping a cog,heard some complaints on that?

Never had a Gibson but I have used a Harvest In 3 combines now one being a 9600. They have been very good for us . They run much quieter seem to require less adjusting feed very good and I have never had an issue with them jumping.

I have had a Gibson for 6-7 years like it a lot, out of all my friends that have put them in I'm the only one with it still in. I would put in JD sprockets avoid the jobbers.

We had an OEM chain that kept jumping until it finally broke. When I got everything apart I found out the previous owner had installed it with one sprocket on the shaft backwards, which puts it out of time a half a tooth with the rest of the sprockets. Just eyeballing them with the header on won't cut it. If a chain is jumping get a straight edge on there to make sure the sprockets are lining up.

The sprockets can be reversed for wear, so I am not sure about what
you have posted.

Sprockets have to be timed or they can be off a half tooth like stated. You can turn them, but have to time them together.

Yep, if you are going to reverse them, make sure you do them all the same. It is possible to put them on that hex shaft a wrong way.
