I'm considering restoring a '56 T110 that my Dad has had sitting in a shed for more than 30 years. The biggest concern I have is that the case is cracked right at one of the cam bearings. I've seen a lot of cases on e-bay that have this same problem so I assume it is a common one.
Is it possible to effectively repair a crack in this area by welding the case? If so, can anyone recommend a shop in the So Cal area with experience doing such a repair? My Dad used to have a shop specializing in British bikes so I think he can help with the rebuild but welding aluminum is something I'd rather leave to an expert.
Can you put some pics of this crack? I have several pre unit engine cases and dont see any cracs. But I run succesfuly engine with welded hole made by broken rod,on front timing side cases!
Due to possible distortion from the heat of the welding process, it is wise to leave adjacent cases, cams, etc intact and torqued. The cam needs to turn freely throughout the process. I had mine done by a local shop in business since the 60's. They showed me a repair that had 10-times as large a hole as mine. Bob
