Walkers DH02 Overhaul and Restoration...Photo StoryBoard

[BelowRadar]

Just one indication of the Care to Detail of the Overhaul...
Specialist Machine brought into Workshops to remove Mineral Deposits from within Radiator Piping...
Multi-headed fitting (this one worn out) utilises the centrifugal force imparted by a rapidly spinning cable inserted into piping to contact the inner walls of the piping with the 'balls', to grind off the deposits without the destructive effects of rotary wire devices.
(That's my layman explanation...I'm sure JF could explain it a little better!)

In laymans terms a tube de-scaler........
Providing the tube isn't corroded to the point where it removes the scale and propagates a leak they work really well.

Engine Awaiting Overhaul.
This is the Engine taken out of the Locomotive, and has been determined to be in better condition than the 'Spare' which has been displayed alongside DH02 in the Workshops for years as the 'candidate' for re-fitment.



Cardan Shaft Awaiting Overhaul.



Cooling-System Fan Undergoing Overhaul.
Interestingly, the heavy steel shroud has had a near metre long section cut out (just visible top left), and a new section fabricated to be installed...All a legacy of its standing in the elements of NQ beneath a Mango tree, the acid from the decaying fruit which collected here having eaten its way through the heavy metalwork.

What a tiny little engine that is!

The Radiator.

One of the first modification’s when the DH's went into the sugar mills was to move the radiator into the long hood.

I take it they have cut a big hole here to fit a auto coupler?



Is that the way up the fan sat when mounted in the loco?

Thanks for that, seemed a pretty empty space with the doors opened.

The fan is very close to its position; maybe turn it slightly to the right
This allows the oil sight glass and filler (top right photo) to be accessed.

I should go get some photo's of DH07 for comparison.
