You can sand that by hand, knock any sharp edges off, aluminum is soft and easy to work with.I have snapped the broken section and will sand down using my dremel.
Has anyone used oil eater to was the inside of the case? I was told bc it has water it could rust up the gears. I can always just use diesel.
I assumed you were, but i was referring to those transmission bearings that are still in the case in your picture. I dont know how much metal was inside your engine but there was quite alot in mine and considering it is a almost 20 year old machine i thought it was wise to replace all the bearings, even the counterbalancers, while i had it apart. It did cost me an extra $150 but i sure sleep good at nightYes, I am cleaning today with oil eater. It’s a water base degreaser and eco friendly. I will be replacing both main bearings .
