A thorough cleaning and inspection of the transmission case revealed some more cracking:
Fortunately, this is the only primary attachment bolt that actually threads into the transmission case. The rest simply pass through and have a nut and washer on the back.
To add insult to injury, there is a piece of broken bolt imbedded in that hole...
Only another incurable gear-head can appreciate the relief that this picture represents. I successfully drilled the center of the bolt remnant, and got it out with the handle end of a rat tail file.
We'll see how Chris does on this one... Our plan is to install a helicoil after the weld repair, in hopes of preventing an instant replay.
Ouch! I can't tell you how many Triumph Pre-Unit transmissions I've seen with similarly cracked mounts.
