Several of you wanted to see the final photo of the Oilamatic Pre-oiler installation. Here it is. Before starting, turn on the preoiler and wait a few seconds as the oil pressure comes into the green. Turn it off and start the motor. Works great. Weight and balance-wise, the preoiler is just a few pounds and is bolted to the top of the pilot's side fire-wall foot recess bucket thing (see the red-anodized preoiler pump. It takes oil from the sump and puts it into the oil filter. The IO-390 is definately heavier. Even though I went from a three-blade prop to a two-blade, there is 57 lbs more weight on the nose-wheel than before (bear in mind that the airplane had not been actually weighed in a very long time, so all the little adjustments to the weight and balance could be off by a significant amount I suspect. A lot had been done to the ACFT since it was last on scales). The ACFT oil temps run hotter than before (with oil cooler relocation and the ARI cowling), and it is no-longer an ACFT that you can do endless touch-and-goes on a hot, humid day in the SouthEast.
