Great poster Jordan!
I should send all interested readers, to an excellent WW2 era report on the R975 recently posted on the Sherman Site. It is the most detailed history I have ever read and I only discovered it a few weeks ago. Many interesting bits of information including;
- many failures due to overheatine, hence C4 styled cylinders
- significant issues with excess fuel during shutdown , therefore degassr shutoff valves
- over reving of engines (engine as brake) spells quick death to engine
- as C1 and C4 share 85% same parts many C1s converted to C4s during major overhauls
and much more!
