Yeah its called use up your old inventory before you use the new inventory. I see this all the time in my line of work. The question is can you get a new shaft? If not can you get one turned at a machine shop. In all my years of servicing pumps in the printing industry never seen one bust a shaft in half. Ive seen alot of locked up pumps that stall the motors or burn up a belt or break a coupling or bust a keyway but never a shaft. Just doesnt seem possible to me. What the shaft 5/8 or 3/4 inch in diameter? Something is not right. That pump was either put together with a broken shaft by a careless employee or made that way on purpose. Either that or the kerosene you used was some potent stuff lol. Getting a new shaft shouldnt set you back too much and after 4 years there no recourse now Im afraid.
