1940 bottom end

Here is a 40 bottom end that my daddy put together over the weekend. Check out all the nice detailing, I love all the nice contrasts on pre war knuckle engines. This motor had the roughest cases that we have ever had to fix up. Some of you long time followers will remember the post with the set of 40 cases that had been poorly repaired years ago. You could literally see light through the cases under the front cylinder.


anyways, here is the repaired case. This is an absolutely awesome job and proof that you can fix up pretty much anything as long as you want to do it. Here is the link to see how messed up these cases were before we sorted them out. http://oldbikesinsd.blogspot.com/2009/09/ryans-1940-cases.html

I posted pics of this case a couple months ago. It is for a 1940 engine that we are doing for a guy in Colorado. It had a lot of cancerous pouros welding that was not good. This is one of the pieces that was cut out.


Here it is next to the repaired case.



The motor mount was really nasty too so that got hacked out and replaced at the same time.




Here is the finished product. Blow it up on your screen and look for pores in the welding. There aren't any. This is an undetectable job and it will last for many years to come. I am very grateful for the group of guys that we work with while turning old junk into useable parts.
