My issue is with removing the Connecting Rod from the piston. I removed the lock nut and threaded a nut about 3/4 way on and hit it with a hammer. The nut went cockeyed and, although it’s hard to see in the picture, it damaged about 1/4 of 1 thread. I ran a cleanup die over it and it looks to me like it’s not damaged to the point that I can’t reinstall the locknut and be okay. However, I’m almost certain any additional attempts to remove the Connecting Rod using this same method will damage the threads to the point that I need new parts.
The reason for my rebuild was major leakage around the big piston at the front of the block. So, I’m hoping replacing the 3 big o-rings resolve it. It seems unlikely that the small o-ring on the Connecting Rod would be a major source of leakage.
I have or will replace every other o-ring. I did not spray penetrating oil or any parts cleaner on the part yet so I have not applied anything like acetone that would damage the o-ring. If I don’t replace this o-ring, I would be careful to only spray solvent on the piston and avoid getting any inside the area where the o-ring is located.
In general, the o-rings I have removed don’t look real bad. I do see damage on one of the 2 big o-rings that fit inside the block which would possible explain my leakage issue. The piston shows some wear, which is rough when scraped with a fingernail so perhaps I need a to look for a piston.
I’m looking for opinions from people who have done this procedure regarding any risk of not replacing this one o-ring.
Or, if someone has any idea on any other method to remove the Connecting Rod without special tools.
