766 Steering Issue

Thanks again for all the help. I have exhausted all suggestions for priming the MCV pump to no avail. No oil or pressure on
a gauge. Now I'm looking at replacing the pump. Thanks again.

It could be a sheared key as suggested in a reply to your other post. Of course you have to pull the pump to determine that.

Well that plum sucks . So now it comes down to pulling the MCV . Here on this not every bolt need to come out you need the ones around the outside for sure and a couple in the upper center these are the longer bolts and a couple shorter ones on the out side . The four bolt in the centr with the washers behind them are the ones that hold the pump to the MCV and do not have to come out on removal of the valve just after to get the pump off . Becareful of the sump check plug and spring , it is located down on the lower right hand side of the MCV . And BTW it is a little on the heavy side . When going back together i use guide studs so that it goes on straight and even as you can bump the sump check plug spring and knock it off while tryen to manhandle it back on . Once back on you will need to run thru the clutch ,dump valve and trans break adjust ment . Get back with me and i can give you the fast easy run down.
