hey guys, at work we had the 9770 upper pulley go out on the variable speed header drive. it is the one on the left side of the machine just before the front wheels. how much should those zerks be greased?? i had been putting 8 pumps in everyday, and when the dealer tore it apart he said the cavity looked dry and what little grease was in there looked black. we're using the HD poly urea (the "good") grease. the dealer told me the zerk that feeds the center of the drum cavity could probably use 20 pumps or so, but i forget which zerk that is.
as your laying under the machine looking at the left side tires, the zerks are at the bottom of the drum. i think he said the zerk on the left (toward the back of the machine) should get more grease. im thinking as your looking at it, the rotation is clockwise, and with the zerks at the bottom of the drum, it will be the "leading" zerk. is this correct??? the book says nothing about how much to grease them, it only tells for the front drum, at 12 and 2 oclock, 8 pumps and 2 pumps respectively. pictures with arrows would also be helpful, just to make sure i get the right zerk! but any help is greatly appreciated.
the 9770 has about 1,000 engine (700 sep.) hours, and we have 2 9670's with about 400 engine hours, and one old 9660 with 1,900 engine hours, and i dont want this to happen again. we only have 50 of 6,300 ac. of corn and 555 of about 2,000 ac. of beans to finish yet and we're done harvest for the year!
9770 runs a 16 row gerringhoff, sometimes a 1293 deere and 635 hydraflex.
9670's run 893's or the 1293 and 635 hydraflex's.
9660 runs 635 hydraflex pretty much just in beans.
