Okay provided you align the pump gerotor assembly as in section 6.9 and place the camshaft in time with the crankshaft. The camshaft pins should auto align with the pump. You not have worry about the governor fork until you do the static adjustment. Either you careful tap the cover in place just in case you need to rotate the crankshaft to get things to drop in place. Note you should the rockers released so there is no tension on the camshaft, rocking it sideways.
