Oh ok sorry. It’s not too bad of a job. Pull the old seal and install new one. Best thing to do is remove shuttle from bell housing so you can get to seal easier, I’m supposing you pulled shuttle with engine. I always put grease in spring area of new seal so it doesn’t jump out when seal is installed.

The pump will separate without any issue if you remove those four retaining bolts.
It may need a little bump with a soft faced hammer to break it free from the housing.
The retaining bolts are offset & the pump can only be installed in one position. It's a good idea to refit the bolts using copper washers to seal the heads.
But I don't think the quadring is the cause of the leak.
I hope you are replacing the visible input seal as well??
Is there any grooving on the converter spout - where the seal runs?
If so, the leak will likely continue after you refit the shuttle.......
also, take a good close look at all the welds on the converter for any cracking - as there seems to be alot of oil in that housing.
