broken Cases
I got these engine cases off eBay. After the small crack from the seller turned out to goall the way though the cases on the original ones. then the new case the Listing mentioned a few things (stripped/re-tapped drain plug and some minor stuff), but didn’t say anything about this broken section.
There’s a chunk of the aluminum casting missing right at one of the bolt bosses in the crank/transmission area. The break is pretty jagged. The sealing surface looks intact and the bolt still threads in with a few good threads left. The cases are still connected solidly in the other spots nearby.
I’m not worried about oil leaks — more about structural integrity. Figure if I go a bit lighter on that one bolt and make sure the neighboring ones are properly torqued, it should be okay… but I’d rather get some other opinions before I button it up and run it.
Anyone seen something similar or run cases with this kind of damage? Would you run it as-is, or is this something that needs welded up first? its a 2006 KX450f
