SA oil pressure solved.

Thanks to all who responded. The link is my first posting if anyone else is interested. Those who said I left a plug out were absolutely correct. Thanks to Owen for mentioning that I could remove the governor and use compressed air into the main oil passage before disassembly to be sure the plug was missing. I could barely feel the air at 60 lbs, but I could easily hear it going into the cam gear area. I then removed the axle and steering mechanism as a unit and was able the rotate the front cover enough to find the end of the oil passage. So, I don't have to remove the pulley. Can't find the plug to go in it, should be able to find one without going through CaseIH. HOWEVER, there are two holes. The one causing the loss of oil pressure is obvious. There is another, smaller one in the upper left corner of the area the front cover hides, directly under where the governor goes. Is this the opening to lubricate the governor, etc? The service manual says:

"The timing gears and governor are lubricated from the front camshaft bearing. A drilled passage in the camshaft journal connects with the bearing oil hole each revolution of the shaft, allowing a metered flow of oil out to the camshaft thurst plate and gear. Oil thrown from the gear lubricates governor and governor pinion bushing".

The hole is threaded, I have identified the plugs in the diagram in the parts manual and there is no plug for that listed. I have not tried fitting anything into it yet, and won't unless someone tells me it should be plugged -- air does not come out this hole so I don't think there is any effect on oil pressure. Does anyone know if this is the opening for oil to the governor, etc. If so, I wonder why it is threaded. Tom Fleming, would you look at your empty block again and see if that hole is there? You mentioned 3 holes, 2 to hold the cam in place and one for the plug. The one I see is not behind the cam gear -- thanks.

I followed the other thread but never commented as I didn't have anything useful to add beyond the others' comments. But since I have first shot on this thread, I'll jump in with what may be a silly question. Are you sure the threaded hole you are looking at isn't one that you unscrewed a bolt out of when you removed the governor?

Oops. No offense, but I hope I don't have similar problems after my split and reassembly. Finishing touches were supposed to happen today. Somehow after 3 months in the shop a coolant hose sprung a leak yesterday and we started ripping the other end of the tractor apart. :shock: Oh well, at least I am fixing it up.

It's not a silly question, because you made me go out and look. It's not a hole for a governor bolt, it IS a hole for a distributer drive bolt that is installed. IH simply drilled and threaded the hole all the way into the governor housing. Did not realize that until I felt the bolt on the opposite side. This tractor is starting to make me feel foolish. Actually with some of the mistakes I have made (the rest of them I managed to figure out myself), I am already foolish. Thanks very much for your help, hard telling when it would have dawned on me otherwise.

I'm getting old, my eyes are no longer connected to my brain, along with a few other things.

CNKS, that other threaded hole is for the govenor I believe. I saw that hole, but it goes all the way through and is threaded as you indicated.

You need to thank Wardner for the air pressure idea. I only added that you might be able to see or hear it if you removed the governor.

Yes, just wasn't thinking, hole is hard to see, first I felt it with my finger, probably wouldn't have noticed it otherwise.

Then I thank you AND Wardner.

You probably would've remembered those plugs had you removed them. If you have a pressure vessel that you can force engine oil into the oil gallery I would use it. That would force engine oil to all the bearings and rocker arms. Hal

Thanks for the info. Another lesson learned.

Hal, you"re a good man for helping so much! It"s good to hear you guys solved this one as well. I just wanted to say hi to let you know I"m still lurking..... I"ll post as soon as I formulate another stupid question!
