i have removed this from the machine and after emptying the mixture of oil and water spent some time cleaning it .The main shaft bearing is worn and i am wondering can it be replaced or do i need a replacement gear box .In all my years of service i have never opened a gearbox before [usually just fit a new one]but as they are now quite scarce i thought i would just have a look and see if there's anything i can do . Any advice would be most appreciated
