I'm trying to keep my model 5124, 1977 Lawnboy (D409 engine) going as a regular use machine. I know the bottom bushing on the crankshaft is very worn and likely contributes to low crankcase vacuum and lower seal wear. Ideally, I would like to source a NOS crankcase assembly. At this point in time, is this too much to hope for? Alternatively, I understand that boring out the lower bushing and replacing it with a bearing is maybe a possibility. I'm not sure what level of machine shop expertise this would require?
Any thoughts or suggestions you may have are welcome.
Thank you.
