That problem is specific to 420 and 500's you wouldn't do it on your 300. My 400ex also doesn't have that problem. I have tried doing it with a torque wrench but honestly that felt like too much to me. I use a 3/8 drive with the socket sticking between my middle and ring finger so that I can't use much leverage to break anything. I broke a bolt off in the case on the ex on the oil filter cover and had to pull the clutch cover off to remove the peice and be able to install a new one.

I know I should use a torque wrench, but I did not strip it out. The bolt will tighten up but it leaks. I am concerned that I may have broke the threads intenally and dont want to break the case down to find out that I didnt. Does anyone have a pic internally of a 2011 420?

The picture I had put up of one broken was a 420/500 bottom end(they are the same case) after it had been broken. If you put your finger in the drain hold will anything on the threads move around like there is a piece broken?

Upon further inspection in daylight, the threads that extend up above the bottom of the case have a slot cut in them so all the oil can drain. Im pretty confident that I didnt break any threads and now just need to concern myself with sealing the drain plug to prevent leaking.

There is a sealing washer on the drain plug, you might need to replace it.

The recommendation in the manual is to replace the sealing washer at every oil change, that may be the problem.
