Chris and his Dad came back out Friday and continued working on getting the blower case off of what will be the mockup for Nelson. Once they got all the intake and exhaust parts off, the PRT's were removed and we went vertical!
Then they took all the nuts off the blower case studs and disconnected the oil lines from the case. While they were doing that, I rigged a chain onto the case and got "Big Red" (our fork lift) in position to lift off the case.
Now that we had the case off and hanging from the chains, I took this shot of the inside of the blower case.
Then we took a look inside the back of the engine. Here is where you get some sense of why it takes soooo long to build one off these!!
We knew from the tag on this engine that it was off a C-119 gunship that flew in Vietnam. We also knew it failed due to metal particles in the oil screen. Upon closer inspection we found some of the reason for those metal particles! The first thing that was spotted was one lobe on the cam had damage.
Next was this lifter roller was also damaged.
This is a look at a good one!
Not sure why there is only damage to one lifter roller and one cam lobe? Maybe you engine guys could enlighten us with your theory of what took place here. That lifter is on the bottom rear cylinder if that helps any.
