End of summer 2010 and finally turning over on air. Work stopped awaiting completion of the building.
First run, bad seat on No 2 exhaust cage meant she was only running on 2 cylinders.
Site inspection by Keith Farley and Paul Evans meeting Peter Stephenson from the Water Authority. Agreement to take one engine and ancilliaries.
On-site, Keith Farley and Paul Evans, removed all fragile components such as pressure gauges and oilers.
Engine No 5 delivered to the museum in part dismantled state. Placed in storage in main yard.
Crankcase installed in the courtyard (Hall 5). Crank installed and block fitted.
First full public run at the 2011 End of Season Crank-Up. Water system incomplete so engine was run with the block filled.

|Conservation/ Maintenance History|
Engine arrived stripped with most smaller components boxed. Crankshaft in good condition, one big-end bearing showed signs of break up.
Strip and Inspection
Crank removed and found to be in good order. Number 3 big-end U/S with a large piece broken out of the top half. Pistons removed, bores 1 and 2 in good condition having been chromed at some point. Number 3 liner in poor condition. All three pistons have stuck rings with several broken. All three gudgeon pins require refurbishment.
Block/crank/flyhweel/outrigger back together. Deflection less than 1 thou all round.
Remaining two flywheel bolts fitted and injection pumps set (by eye)
Knock on No 3 so big ends checked.
Big End Clearances

General sorting of remaining small jobs, missing studs, fuel leak on manifold.

End of Season/Victorian Night/NYD 2011
Cooling system pressurised with no leaks. Engine ran for 2.5 hours at Victorian Night. Ran for 5 hours at New Years Day event with no problems other than hunting on the governor. 5 gallons of fuel consumed.
