Disassembly Complete

Today I finished up disassembly of the Corvair motor. Here's a last picture:




Now I'm going to have to clean it all up!

Case, Crankshaft, and Cam ...

Is all that is left. Here is how it went:


Note that one of the cylinders came off with the head. I have already removed its piston / connecting rod in this photo. It took a bit of giggling and some slight hammer taps on the cylinder tabs to loosen it from the head. I did not BANG on it. Instead I tapped back and forth, rotationally, spraying lots of penetrating oil and letting it sit between workings. Eventually it pulled off. The trick here is patience. If you BANG, you'll likely destroy.
Also in the pic above one of the cylinders and pistons are locked together. The cylinder / piston have pulled off of the case by rotating the crankshaft. I never used any significant force. Rather, I followed the good advice in Richard Finch's "How to Keep Your Corvair Alive": very small movements back and forth, with lots of lubricant and take plenty of time. When it moves just a tiny amount, you've won the day. It will come apart in due time.


Next off: the bell housing. That came off easy leaving this last bit:



Taking the last two

Cylinders off today. Pics to follow ...
