Final Assembly series part 7
Yes, I know some of you call it a donkey start.
After a few final touches and installing the main diesel we are ready so start the starting engine. Fingers crossed! 1939 Caterpillar D4 / RD4 4G9986 "Lil Lefty" has never been so much fun and fulfilling. I hope you enjoy the shop talk, banter and commentary.
We are operators pretending to be mechanics!
Thanks for watching!

Aaron & Greg "The cleaner"
