 31418 Overhaul News

All traction motors have been washed out , cleaned up , re-brushed and their cables re-connected.

Recent work on 31418 has seen A3 - A6 & B3 - B6 cylinder heads removed and A3 - A6 & B3 - B6 pistons, con rods and cylinder liners removed.  A3 & B5 pistons were seized inside their liners and were lifted out 'as one' and separated with a hydraulic jack.

All the pistons are in excellent condition and will not require any work other than cleaning up and re-ringing. The con rods have been examined and will be re-fitted.  A3 & B5 cylinder liners have been scrapped due to water damage but the other 6 will be re-used following honing.

Work has also commenced with overhauling the cylinder heads and 4 are ready .

The damaged no 2 bogie from 31418 has been sold and recently cut-up at Swanwick.

The 'engine roof panel' has been shotblasted / primed and temporarily re-fitted. Cab roofs and some of the bodysides have also been shotblasted / rubbed down and primed.

A6 + B6 liners , rods and pistons have been re-fitted. New big end bearings have/will be fitted throughout and all rings have/will be renewed on the pistons.

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 new oil added.  It now spins freely and has been painted ready for fitting.          The 'B' Bank turbo has similarily been dealt with in-situ and also spins freely now.

Status

 

Planned Work 2008

 

 

 

Undergoing long-term restoration to working order.

 

We hope to have a major 'push' with the overhaul of this loco during 2008. The following is a list of planned work for 31418 this year:

  1. Continue with power-unit overhaul.
  2. If shed space can be obtained , commence body overhaul.....lots of new steel required !
  3. All roof sections to be shotblasted and painted.
  4. Concrete block to remove and corroded air pipework to replace. Boiler room (no 1 end) area to clean and paint and 31162's original boiler to cosmetically restore and fit.  The boiler water tank ex 31123 will also be cleaned up / painted and fitted. A new bulkhead archway will also be fabricated and fitted to replace the corroded one presently there.
  5. ETH cubicle ex 31421 (already electrically repaired) to be examined , painted and fitted.
  6. All Main Gen , Alternator and ETH cubicle cables/wires to re-connect.

Bogie 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.
