While trying to adjust the front pto clutch on my 318 I noticed everything was extremely loose and I couldn’t get it to adjust properly. Upon inspection I discovered that the collar inside the bearing was extremely loose on the shaft. It looks like the collar is not being held in place by the key and therefore spinning free on the shaft and causing wear. I believe someone replaced the key at one time and it is too short to grab the notch on the collar. I’m hoping the majority of the wear is in the collar and not the shaft. Does anyone know where I can purchase a key, collar and new bearing?
