Do you have a pic ? I never ran into this when I did mine 3 week ago . I undid the little bolts holding the shaft on each end popped the shaft from the rear did the starter and put it back .What bearings are you talking about ?Do you mean install one ball bearing at a time? The retaining ring has six slots and I thought they all had to be pushed in at the same time. Does anyone know if it is easier to start with the ring and bearings on the shaft or in the socket?
