The Temora Aviation Museum Engineering staff have been carrying out preventative maintenance work on the Museum’s Lockheed Hudson. The procedure involves removing and replacing the ignition harness system in the right-hand Wright R1820 engine, due to the original harness deteriorating with age.
The new ignition harness was sourced by Temora Aviation Museum Engineering Chief Engineer Peter Pring-Shambler, from Texas USA. The harness was produced from scratch, using all new parts. The harness has two distributor blocks for the magnetos and eighteen ignition leads to attach to the two spark plugs per cylinder, of the nine cylinder radial engine.
The ignition harness change is anticipated to be complete by mid next week, ready for the Hudson to participate in the next Museum Flying Weekend on 30 June and 1 July.
