Engine bearings, crank, cam, piston & sleeve removal 1941 Caterpillar D4 parts for Lefty Episode #61

We open up the D4400 engine from the 7J parts machine, will the bearings work? The story of lefty and the 1941 Caterpillar D4 7J4265 W Parts Machine continue to meet. We need to see if the parts machine has what we need to finish Lefty! Overall, progress continues on the 1939 Cat D4 agricultural crawler. 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! Regards, Aaron & Greg "The cleaner" Episode #61 LAOL P.O.
