LATEST winning idea in this series comes this week from that prolific source of practical suggestions Mr. D. V. Brown, of Tottenham, London N17. This time the subject is BMC diesel engines. When it is necessary to change a DPA pump, he says, it is nearly impossible to fit the replacement without removing the casting between the exhauster and the pump, then lining up the master splines, refitting the casting, then fitting the pump.
Mr. Brown says he found a scrap coup ling and a DPA pump driving shaft and modified them to act as a mandrel, which saves removing and refitting the mounting casting. The old pump can be removed, the mandrel inserted in the master spline on the exhauster coupling—and the new pump is lined up with the mandrel coupling and slides in when the mandrel is removed. This saves about half an hour.
Comments Handyman: As usual this man has come up with another useful idea from scrap material.
