Hello I am Martin, experienced in mechanics and computers, if you need any help? do not hesitate to ask me. If you are near Featherston and need help with a computerised Milking set up, I would like to help you, for the knowledge.I have been a European mechanic and have a good overall knowledge of mechanics. Just repairing a DAVIES RENOWN 200 Pump, at present. I got parts for this pump at Ordish & Stevens in Masterton, the only place that I could seem to get them.
Anyone who has pumps on their property it is good to do oil changes in them every 6 months, at least every 12. As in cold conditions, you will get condensation in the oil and it will cause metal fatigue, in the crank.
Davies pumps are good sturdy pumps, I would say, as the person I have fixed one for, has had it going untouched for 18 years. They must be good. The pump itself must be 50 years old. Still good!
