This is from the report no 174
Durability
Only one drive system was used for all tests. No appreciable gear wear was discernible and the injection pump drive tang had no appreciable wear. The gears were made from camshaft cast iron and were unhardened but were given a special shaving operation. The drive shaft was made of unhardened cold rolled steel. On the basis of the above performance the durability of the Bosch system can be considered satisfactory with one exception, The exception is the unknown effect of running time on fuel delivery characteristics. No tests were made to investigate this effect.
This is from Advanced Engine Engineering November 4, 1955
Endurance test run on vertical drive unit completing 80 hours at speeds ranging from 800 to 4,000 rpm. Wear pattern satisfactory and no indication of heavy wear yet.
