Re: Pump gear what if?
It's possible. Precision is the key to pumps. Clearances between tooth-end to case and gear-end (side clearance) to case are the critical measurements - they must be as close as possible to prevent oil from "slipping" by. Since you are rebuilding a pump, there might be wear that must be compensated at both tooth-end and sides. Don't know the original specs for the Magom pump, but tooth-end to case is probably .001" - almost touching. Side clearance is probably similar. If your case is worn it could be reworked to clean up the tooth-end area (outer diameter of the gears) - again, a very precise operation. If side clearance area is worn, the end plate could be ground flat to give a good sealing surface, but precision is key.
Since pumps are normally hand fitted during assembly, I can't predict what your success will be. A few years ago, someone on the Forum built a gear pump from scratch (don't remember who) and had some decent level of success. Maybe your repair will work.
Forgot to ask - how badly worn is your original pump? Is it not pumping well? Low flow or pressure or both?
Good luck!
