Assisted by Al Cowan & Andrew Harper, the main shackles and the front tensioner are correctly positioned |
Taking the strain |

Suspended form the crane, the generator is slowly inched upwards.... |
...and out of the locomotive |

Stuart checks the load is fully clear prior to allowing the shunt to proceed |
The flat wagon buffered against the loco, to be shunted in line with the suspended load |
Mid way through the shunt |
The generator is lowered into position |
Strapped down on the flat wagon |
The train is shunted back into the yard to await collection of the genny |
After removal of the exhaust stack from the turbo, the studs were re-threaded with a die-nut |
Al Cowan welds up the holes the exhaust stack to allow new studs to be fitted after griding and re-drilling & tapping |
The top of the stack awaiting grinding |
The four filter elements from the turbo have been degreased and steam cleaned and are seen here in primer |
The rear covers and other parts cleaned and awaiting refitting once the genny returns |
The generator awaits collection |
The space left by the generator is being fully degreased, steam cleaned, rubbed down and repainted whilst the genny is out. It's also hoped to repaint the whole engine compartment prio to the generator's return |
Coupling bolts removed from the generator & engine shaft, all individually marked to allow correct repositioning during refitment |
The turbo undergoing a strip down and clean-up |
Local contractors, Thomas Graham, carry out the haulage of the generator (and a class 26 traction motor) to Glasgow. Wednesday 9th May. Photo courtesy Alastair Cowan |
Signs of damage to three of the poles |
The carcass after three and a half hours of steam cleaning |
The lower section of the genny |
Close up of burn damage to the tape and through the insulation |
Starter motor/Aux Genny |
Adaptor attached to allow the armature to be lifted and for work to be carried out |
The 'rear end' of the armature still awaiting steam cleaning |
Clean commutator on the starter motor armature |
The main part of the armature requiring cleaning then re-varnishing |
Cleaned terminals |
Close up of the terminals and how the coils are linked together |
How the varnish should look - the uppermost poles |
More dirt and a hole - needing a good clean and repair |

Part of the air brake piping dismantled, to be reassembled ... |
... after this piece of pipe is replaced due to bad chafing - several years worth of wear! |
The cab light fittings, before & after |
Still with original pitted & rusting chrome |
Now with a fresh coat of white enamel. the fittings will be stripped & rechromed at some point in the future. For now though, this smartens their appearance considerably. |
1st June 2007: The carcass with most of the coils present, being rewired & taped |
New insulating tape on several coils |
One of the brand new coils, covered in glass insulating tape and with a first coat of varnish applied |
A brand new coil, currently being isulated with glass tape |

The old coil for which the coil in the previous photo will act as replacement |
The two other old, damaged coils |
These blocks hold the coils in place |
New wire being installed and spaces for the coils |
Close up of new insulation |
Opposite side of the carcass to the earlier photo |
These coils require re-taping, the one in the background will have the old tape removed and be retaped as well |
The armature cooling in the stove (gas Mark 6 for 24 hours!) |
The old PTFE banding on the main gen has been replaced with stitched glass tape (yellow) impregnated with epoxy resin which shrinks the tape to keep it firmly in position, The white tapes on the main commutator were just there during the process and will shortly be removed. The aux gen PTFE banding is ok and will remain in place |
A view across the workshop, with some other jobs in view, varying in size from very small to even larger than the class 26 genny |
The retaped brushgear ring |
Not often seen - the ball race for the generator bearing - after ensuring it is fit for re-use this is to be cleaned and reinstalled |
Brushgear & aux gen stator all cleaned, reinsulated & painted. 07/06/07 Photo courtesy Stuart Sellar |

Sitting ready to accept the aux gen stator & brushgear, the main generator looks a far cry from the state it was in when it entered the works only 4 weeks previous. 07/06/07 Photo courtesy Stuart Sellar |

Three happy chappies; Al Cowan, Stuart Sellar & Andy McLean after the realignment. Top work chaps - have a gold star! Photo courtesy Al Cowan (presumably on self timer, propped up on some crates!) |

The reason behind the terrible mess inside the genny and all over the engine - the new weld now replacing massive cracks all the way round the crankcase breather should ensure it doesn't happen again. Photo courtesy Al Cowan |
