Engine/Transmission (1994 - 1998) Power steering/vacuum shaft connection

[Beck]

I was replacing the PS pump and the shaft connects to a 4 way key inside the vacuum pump housing, from the opposite way a shaft from the vacuum pump also connects into the same 4 way key, everything was fine and I had wonderful power steering again, except a major PS fluid leak from this zone where the two shafts key together, my question is does this round gasket in the pic go with its back against the shaft key or at the top of the housing ? I had to take it out to have a mounting hole welded that broke and now I'm confused, the gasket must be the source of the fluid leak and got slightly deformed taking it out, does anyone have a service shop manual on this subject of advice ? IM screwed like a pooch here and need some help, could be a simple as a new seal for all I know, Thank You

Try checking fixinrams.com I thought he had a video on there that might show it

The seal in the picture is for the vacuum pump to seal engine oil. I don't see how you could have damaged the power steering pump seal. It should still be on the pump unless it blew out for some reason and that is it in the pic. Did you look at the pump seal? Is it there or is it gone?

Here is a video that might help: https://video.search.yahoo.com/video/play;_ylt=AwrSbnvbm8lWqyQA9CRXNyoA;_ylu=X3oDMTEyOGRqY3NyBGNvbG8DZ3ExBHBvcwMxBHZ0aWQDQjExNzlfMQRzZWMDc2M-?p=rebuilding+the+dodge+cummins+vacuum+pump&back=https%3A%2F%2Fsearch.yahoo.com%2Fsearch%3Fp%3Drebuilding%2Bthe%2Bdodge%2Bcummins%2Bvacuum%2Bpump%26ei%3DUTF-8%26fp%3D1&fr=%26fr%3Dyfp-t-694-s&turl=http%3A%2F%2Fts2.mm.bing.net%2Fth%3Fid%3DOVP.V88d7362462f8da132072c6a7459b3ed3%26pid%3D15.1&rurl=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DF0m0UlzJvvc&tit=Cummins+Vac+pump+rebuild+%2C99%2F96+Diesel+Swap+update.&l=277&vid=e4e70e2ff3e430745d5192ec120e70d8&sigr=11br8aqo5&sigb=12out8qgr&sigt=11jlhg1dv&sigi=12bihoj9i

Excellent video on the proper way to rebuild a cummins vacuum pump.
13 minutes 20 seconds into the video just might explain your problem.
