I am new to this site,first post from me so please bear with me.I have a 95 R52 and am having problems with front feederhouse chain.At least once per year chain will ride up on right drum ring.When this happens,get ready,it is slat replacment time.I read here of a different drum ring.Is this what i need or do i need to look elsewhere for the problem?the chain is kept set per ops manual.The chain was also reslatted before start of corn harvest.Any and all help will be appreciated.By the way,i am in western ky.and the machine does corn,beans,and wheat.
