I earlier posted a question about either an engine or case as a fix for the cracked case we found on my C-150. We have learned there is an approved fix for a cracked case involving welding the crack. That is all I know about the process; except should the case pass all other checks the case is given a yellow tag. My IA says there is an engine shop in TUL that can do this. Anyone have information this procedure?
Roger,
Repairing a case is a specialized repair, and only Divco has the approval to do this. It is possible that your cracked case is non-repairable. Send a photograph to Divco to find out if repair is an option. Otherwise, you will need to replace the case with new or a serviceable one you can have "overhauled".
Now is the time to sit back and take a deep breath, and evaluate your options.
To repair the case, the engine has to be completely disassembled.
The current time on your engine and cylinders may make doing a major overhaul a prudent decision. Also, if you did decide to do a major overhaul, using a "repaired" case might not be wise, and a new or good replacement the better choice.
