Roller Bearings All axleboxes , coupling and connecting rods, little ends

Fox in June 2005:

In mid 2004 Fox suffered an inner firebox failure. To repair the firebox entailed removing the boiler from the frames. An initial temporary fix enabled the locomotive to be placed back in traffic in mid-2004. However to help prevent a recurrence of the problem in the Autumn of 2004 the locomotive was stopped, the boiler removed and repaired at Clayton West works. Whilst the boiler was being repaired further improvements were made to the locomotive.

Valvechest and Piston valve renewal and Cylinder Insulation:

In line with the policy of gradual locomotive improvement the locomotive, originally built with slide valves, received piston valves as replacements several years ago. However these were a direct bolt-on replacement and thus were arranged with the less than ideal system of outside admission. During the work over the 2004/2005 winter and spring these valves and valve chests were removed and replaced by a new design of outside admission Porta type piston valves. The design work was undertaken with Shaun McMahon acting as consultant. Outside admission valves remain less than ideal but coupled with the hugely increased steam chest size a considerable increase in power and a reduction in coal and water consumption have been noted. To replace the outside admission valves with inside admissions would entail a total cylinder replacement and a redesign of the valvegear.

Lubrication of the piston valves has been arranged to be 'between the rings' rather than the normal 'put it in the steam chest and hope' approach. The feed from the mechanical lubricator remains proportional.

The cylinders have been (relatively) heavily insulated, much in the same manner as on FCAF No.3 'Camila'.

A close up of the between the rings mechanically fed lubrication. In addition to the layout of the valvegear the positioning of the feeds gives away the fact the valves are arranged for inside admission. June 10 2005

Boiler Work:

In addition to the boiler repair the set of water level test cocks have been replaced by a tubular type gauge frame and glass.

The right hand gauge frame is new. Previously there were a set of test cocks. June 10 2005

Increased Boiler Insulation:

The opportunity was taken to increase the boiler insulation. To accommodate this the side tanks have had to be pushed out a little.

Raised Cab Profile, Repositioned Side Tanks and Enlarged Coal Bunker:

To make the locomotive more comfortable to operate, and improve her appearance when coupled to the line's carriages, the cab roof height has been raised to be approximately in line with the carriage roof height. The coal bunker has also been increased in height. The side tanks have also be repositioned to suit the new arrangements.

Clearly shown here is the KLR produced duplex air brake pump. The cylinders on this locomotive were originally fitted with slide valves. However they have now been replaced with piston valves - the valve chests were swapped leading to less than perfect steam passages. None the less it is a step up from slide valves. April 11 2004
