| 340 To By.{R.W. Bailey - Chief Engineer} from Rm{William Robotham - Chief Engineer}/Std. Rm{William Robotham - Chief Engineer}/Std.5/AP.30.12.36. CLEANING OF P.III. OIL TEMPERATURE REGULATOR MATRICES. Rm{William Robotham - Chief Engineer}/GWH.{George W. Hancock - Head Chateauroux} has brought to our notice the fact that although instructions are given in our Phantom III. Instruction Book for cleaning the oil temperature regulator on the Ph.III. engine, no equipment is provided for this purpose. We were under the impression that as the Drawing Office compiled the instruction book, they would have instructed the necessary equipment, but apparently this has not been done. All that is required is a suitable size syringe or hand pump with the necessary adaptor union to enable it to be connected to the oil cooler matrix unions. The cooler is then immersed in a bucket of clean Benzol - Benzol is drawn into the cooler matrix and pump and then expelled into the bucket, this being repeated a number of times. Finally the cooler is blown out by means of a compressed air line. We have measured the volume of the cooler matrix - approximately 18 cu.ins. - this should be the approximate swept volume of the hand pump or syringe. Will you please instruct the necessary parts to be made and supplied to our Service Depots as soon as possible. It should be possible to buy suitable syringes and make the necessary adaptors.
