Sentinel 9559 Engine Re-build Continues

The re-build of Sentinel 9559's engine is quickly advancing to the state where it can be timed and components for oiling have been re-fitted to aid in this process. With the mechanical lubricator cleaned and bolted back to the engine frame, Robert and Steve have started rebuilding the extensive lubrication system.


Aside from the engine, Aaran and Robert have dismantled and are in the process of reassembling the reverser mechanism, reach rod and associated gear selection components used in timing the engine, pistons and cylinders. Machined by Aaran and Robert, new pins for the reverser mechanisms replace previous ones which were life expired and unfit for re-use.


Also, Robert has been completing some painting duties of the new cylinder covers, gear changing mechanisms and oil reservoir tank that feeds the drive chains of the engine.



Steven working on refitting the oil filler pipe to divert the oil feed onto the gears.


Robert cleans and de-greases the oil reservoir tank prior to priming.


Once primed, painting can progress prior to attaching back to the front of the water tank.
