Combines R 75 variable shieve trouble

My advise is give it 80 pumps of grease before you start. It takes at least that before grease starts to do it job at all. Inside zirk isn't important at all as long as zirk near coupling gets enough to get the job started. The normal daily prescribed greasing of that spot likely didn't get grease to where it is needed in the 100 hours you run it if it wasn't filled before you started. Keep this in mind and get it filled right off the get go and you will have no problems with that varible. That varible and cylinder varible are the two very important zirks on whole machine but often don't get filled well enough at factory or at dealer predelivery. By the time your grease was starting to get near where needed you had a failure. There is no way in this world you could wear out this varible in 100 hours if lube would of been there. You might want to study grease flow when you disassemble and you will find cavities were not yet full of grease which allowed sheaves to run on nothing more than assembly lube. We have lighter duty corn varibles (prior to '98) with over 30 years on them and going strong. None of them got over a couple years if not first filled with greased and then greased regularly like op manual suggests. Best of luck

We have logged over 10,000 hours on this design without a failure. I put 10 pumps in it this morning as we have done for 25 years. What about the cylinder sheave, should we put a couple tubes in it alsoIJ Thank you for the input.

I read again and you already adressed the cylinder.

Cylinder varible is basically the same exact setup but cavities that grease needs to fill before doing its job are much smaller. Thus cylinder varibles are rarely a problem. Well I should say rarely a problem if it gets serviced. Now with corn head varible normally having a fair amount less load than cylinder varible it only makes sense it should not be a problem (that is if it gets lube before it is allready to late). Now with some of the chopping heads these days that varible does get worked to the MAX. If you just can't get that varible to last with good maintanance then Clinton Ag. has a heavy single speed set up for you. Best of luck.
