If it is any help to you , Paul , -there are several sites , mostly in the US , some here ,where you can locate , and have the parts shipped to you - I've had , often , to call out for some of the boss's machines here , we have a range of equipment , from full track Bobcat 2 - speeds , to modified farm tractors , mostly John Deere , we have a Case 4490 tractor , and so on - the boss does not like to purchase from the dealer unless he has to , the price on some of the items we have to replace would straighten your hair out , you get the idea . The Case IH dealer I work with here for parts supply put us on to several aftermarket places , all online , there are even some industrial machine , and agricultural machine recyclers on line as well - way cheaper than the dealer - it might be worth your time to have a look , could save you some greenbacks - hope that helps - good luck -
