WORK COMPLETED / IN PROGRESS DURING 2012
A poor but ‘usable’ set of batteries have been fitted to enable the testing of electrical circuits / machines. The fuel transfer pump and lubricating oil priming pump have both had their commutators cleaned up and brushes freed off and have been ‘run up’ off the batteries with no problems. The engine room lighting circuit has also been tested as well as the marker / tail lights. All are now ok following renewal of a few bulb holders. Following renewal of a fire detector holder and attention to the fire alarm relay and test switch, the fire alarm system now works correctly in both cabs. The fault lights for low fuel, high water temperature, low water level, earth fault & traction motor blower failure have also been tested in normal and fault conditions and are working correctly. An SSF unit has also been fitted at no 2 end.
Both no 1 end cab doors have been completely stripped down to enable renewal of the door drip tray and bases. No 2 end doors have been re-fitted and are in the process of having panels and glass fitted.
‘A Bank’ radiator shutters have been rubbed down and primed. ‘B bank’ shutters will be similarily treated shortly.

31418 Overhaul News
All traction motors have been washed out , cleaned up , re-brushed and their cables re-connected.
All cylinder heads , pistons, con rods and cylinder liners were removed from the engine block. A3 & B5 pistons were seized inside their liners and were lifted out ‘as one’ and separated with a hydraulic jack.
All the pistons were in excellent condition and did not require any work other than cleaning up and re-ringing. The con rods were also thoroughly examined.. A3 & B5 cylinder liners have been scrapped due to water damage but the other 10 have been re-used following honing.
All 12 cylinder liners, pistons , rods and cylinder heads have now been re-fitted.. New big end bearings have been fitted throughout and all rings have been renewed.
The ‘engine roof panel’ has been shotblasted / primed and re-fitted. Cab roofs and some of the bodysides have also been shotblasted / rubbed down and primed.
As a result of severe frost damage on the ‘A’ Bank turbo on 31418’s power unit (ex 31421) , the ‘A’ Bank turbo recovered from 31123 has been de-carbonised , freed-off and has had new oil added. It now spins freely and has been fitted and painted. The ‘B’ Bank turbo has similarily been dealt with in-situ and also spins freely now.
The ‘exhaust roof panel’ and the ‘ electrical cubicle roof panel’ have been shotblasted / primed and the ETH cubicle has been examined, painted and refitted into the loco.
Nose end doors , louvres , cab doors and skirting has been removed for shotblasting / repair. Some of the corroded bodywork has been cut out ready for replacement. The nose end doors are to be replaced with newly fabricated ones.
The concrete block (ballast weight) has been removed and the boiler, which has been cosmetically restored, fitted in its place. The boiler water tank (ex 31123) has been shotblasted, painted and fitted into 31418. Three corroded air pipes in the boiler room have been replaced and the boiler / radiator area cleaned, primed and top coated. The boiler area roof section has also been shotblasted, had corroded steel replaced, painted in primer and re-fitted. The emergency fuel tank along with the rad fan cowl have also been cleaned up, painted and re-fitted.
Work continues with the power unit and cutting out corroded steel and replacement which is now concentrating on the cab doors which require re-building.
Only the fuel pipes to / from the injectors and the injectors themselves require fitting to make the power unit complete.
All skirting has been removed and shotblasted. Most sections will require repairs. Both nose ends have received a thorough cleaning , rubbing down and priming. 21/08/08

‘BEFORE’ ….. Serious corrosion around the no 1 traction motor blower air intake is seen here. Most of what ‘should be there’ has completely disappeared and will therefore require rebuilding. 23/08/08

|StatusSummary of work done in 2009||Undergoing long-term restoration to working order.During 2009 a major step forward to seeing 31418 running was achieved with the following major achievements, thanks to our dedicated workforce.
|Summary of work done in 2010Bogie swap / Body lift||
As a result of sustaining a collapsed suspension tube bearing to No 4 wheelset whilst in British Rail ownership , the decision was taken to change No 2 bogie completely for the No 1 bogie recovered from scrapped 31123.
The underframe was treated to 3 thorough steam cleans , it was that bad ! , and claws , cables , pipes etc were disconnected . 31123’s No 1 bogie was overhauled and repainted then converted to a No 2 bogie by the fitting of AWS. Over 4 days Thursday 15th Feb – Sunday 18th Feb 2007, the bogie exchange took place in the PRCLT West Shed at Swanwick.
On the Thursday , the loco was lifted from its bogies and both bogies removed. The No 1 bogie being taken ‘downstairs’ for steam cleaning and the No 2 bogie placed for storage. The Friday saw more steam cleaning to the No 1 bogie after which it was positioned back inside the shed for drying and for a small amount of repairs to be carried out. On the Saturday the bogie was re-painted and repairs carried out on the loco’s underframe. Finally , the Sunday saw 31123’s bogie brought ‘upstairs’ and later in the afternoon both bogies were carefully positioned underneath 31418 and the body gently lowered down.
31418 was taken back ‘downstairs’ and placed into storage. Claws , cables etc will be fitted shortly………another major step forward……!
31418 is positioned ready to be ‘set up’ for lifting at West Shed on 15/02/07.
Bogies are removed from underneath 31418 by Class 03 D2138 on 15/02/07.
No 1 bogie ex 31418 is steam cleaned at Swanwick on 16/02/07.
31418 sits on the jacks awaiting the return of some bogies on 16/02/07.
No 1 bogie receives finishing touches following repair and painting on 17/02/07.
