Thanks for the replies.
OK, I need to do some thinking out loud now. I have the pump sleeve in now and in correct alignment, I don't (really don't!) want to have to take it out again. If the housing is distorted, reaming it out is going to take it oversize somewhere, so there is a possibility of leaks or loss of oil pressure? I'm not quite clear what Vincent is suggesting, is the honing to the sleeve or the housing, or is it both? It's a bit late for the housing in my case and even if I were to pull the sleeve out again and do it, it may distort again when it goes back in leaving me where I started. There appears to be some damage to the housing around where the outer main is driven in, I wonder if this is the source of the distortion? It would make sense if the housing is out of true that the plunger won't go in, but if I ream the inside of the sleeve I would have to be dead accurate or oil will be able to get past the plunger affecting the oil pressure which I don't want! Is this correct? Or does it matter with the nose of the plunger, as this doesn't appear to transfer any oil. It's nice to know that warming the cases won't affect the Loctite as I don't want to have to go through all that again.
"Than some very fine abrasive powder oil and thats it.
Be sure to machine down the middle part on the sleeve whom is open.
As it can bend"" the sleeve when seated.
Than do the pump itsself with fine "Time saver lapping compound. "
Vincent, can you please advise on "abrasive powder oil", I'm not familiar with the term. Is this carborundum oil such as used to be used for running in? When you say machine the middle part do you mean concentrate on this section as it distorts when fitted? Is "time saver lapping compound" what I would know as valve grinding paste?
