If the oil sleeve uses a woodruff key (half moon style) it could be possible that the top of the key isn't parallel to the od of the shaft. If this happens, or if the key starts to rotate in its keyway, it can cause issues sliding the oil sleeve in. But, I don't recall if the key used for the sleeve is this style or not.
Also, as mentioned above, I would first check to see that the teeth on the sleeve are meshed with the oil pump. If not, they may be hitting the oil pump teeth and keeping you from inserting it further.
Finally, any reason that you put the seal in first. Normal assembly procedure for machinery (and engines) would be to install the seal last. If you did this, it would make it easy to see if the teeth are properly aligned with the oil pump. And, you only slide the seal over areas of a mating part that are intended to be a seal surface (ground to the finish that won't damage the seal).
