pressure wash that engine very good and do it on the back of pump too. Clean it good and then clean it some more.
Remove oil lines for oil cooler and turbo. open side plate on pump and align marks in the window. Remove injector lines and then unbolt pump and pull off.
Remember cleanliness is absolutely required when working on this stuff.
Get all new seals for all the lines and might as well pull injectors too while your at it.

Tom Westerfield this is what i was told
DO NOT STEAM-CLEAN OR PRESSURE WASH THE
PUMP WITH THE ENGINE RUNNING OR HOT
There is a little bitty cover on the pump body held on by two screws.
Take that cover off and bar the engine over until you see the
line on the rotary part of the pump line up.
Then you can take the pump off and put it right back on in time.
Be very careful with the two seals on the drive shaft.
They go on so
that the lips point out, away from each
other. One seal facing the pump
the other seal facing the crankcase.
Be sure that the lips of these seals don't get folded over
when you re
install the pump. If the seal leaks, the Diesel
fuel will be forced into
the crank case by the pressure of
the fuel transfer pump.

I have never done it on a 190, but on my HD3 crawler when I pulled the pump off to have it rebuilt, I could not get the timing marks to line up before I pulled it off as just as it would get to the timing mark, it must have been right at the top of the compression stroke and it would go past it. So what I did, since I was sending the injectors in also to have them checked over is I pulled out all of the injectors. That way with no compression, I could get the pump right where I needed it. Once the timing marks are lined up perfect, it's easy to pull the pump off and reinstall later and not get the pump timing all messed up.
