I can see that this one has been addressed a few times but I cannot find a thread where the final solution was posted. I have a B2400 HSD ser# 76244. I cannot figure out how to get the replacement seal in place. I cannot get the cover off. Yes, I have the WSM and I am not seeing the retention rings that are referred to. Here are some pics. Hopefully I am missing something simple, I love this tractor but I can't dump hydraulic oil all over my yard ;-)
