At our first work session in 2015 Joel and Kent started installation of the "new" 1970s CVCC alternator, per recommendations from Van's Aircraft and an EAA technical counselor Kent met in Oshkosh a few years ago. Below are three pictures of our initial work compared to a completed installation. This task requires the following:
1. drill out slightly three top holes in the alternator mounting bracket (from Van's)
2. fabricate mounting bracket for tensioner arm (supplied by Van's) from steel angle stock
3. fabricate tie brace to connect lower alternator boss to alternator boss
So far things are going according to our expectations with no major challenges.
