Arthur Man I will be at a loss when this ends. It has been quite something to look forward to in the morning with coffee. OK I gotta babble. I had to kind of understand this thing in my mind. The word timing kinda threw me at first. Actually the tractor won't care how you throw the oil pump in, but how it is inserted will effect where the rotational position of the dist is when you set up no 1 to fire. So get her up on DC (mark on flywheel as you are looking thru the timing hole) for no one when it is on the firing stroke. Look at the slot in the top of the oil pump. This is where the drive fingers fit into from the distributor. Notice it is cut off center. So as you slide the oil pump up into the gears on the camshaft the oil pump shaft will rotate some because of the way the gears are cut. The 40 book says as you slide the oil pump up on the cam gear and as it seats for bolting up, the narrow side of the coupling it to be toward the tractor. So when you drop in the dist and it falls into the drive slot it should be aligned (when you set it up to fire and manually time it for no 1 - this is described in the ops manual, I don't remember if in the service manual or not) the dist will be aligned for ease of reconnection of the coil wire and aligned relatively as it was from the factory. I could not get my slot tocome out "exactly" as described but it was close. Somewhere on the oil pump will be a plug which leads to the relief spring and the shims that set the tension on the relief spring. I am stealing Wayne's thunder but heard it too late on mine. I don't think it will hurt to goose up the pressure by one shim of the thin size. I don't have the details on this so I don't know if you add or take out. It will be apparent when you take the plug out and check the spring and ball. I would think the shims compress the spring and give more pressure when more shims are addes but I don't know. Anyway you better have a look see at the spring and ball while there. Now for the rocker stuff. There is a cavity behind the camshaft that has to fill in a regulated flow even before the oil starts up the tube going into the head. So oil down the rockers before starting. Then start and observe for oil pressure. If you got that then you can worry about the rockers oiling. As i foggily recall, oil will show up at the hole in the the top of the rear rocker first and then slowly show up working from bact to front until it is slowly flowing out all the rocker tops. If it don't work out that way, you can always pull the tube going into the head and if you don't have a slow flow of oil there -- welll then we will just have to invent some new words. If you get so tickled because your new toy ran ok don't forget to post back so we can close out this series lol. here is wishing you good luck.
