The pump is bolted together from the back side (front and rear halves). Pull all the bolts from the front behind the torq con. Forget how many (8 or 10?). Two of the holes are threaded for the next oversize thread. Install the correct size threaded bolts in these two holes with a piece of chain or use a threaded slide hammer to knock the pump forward. The important thing is to get it out straight. Don't get it cocked in the bore. To install, put vaseline around the rubber seal and the trans housing and use all the bolts to gradually and evenly reseat the pump. Hope this helps you.
