This view shows the damaged concertina found on the silencer elbow an inherited legecy from the when the power unit was removed from the loco prior to delivery to Toddington. The group is desperate to find a replacement and, so far, we have drawn a blank. The original manufacturer, we are told, is Gloster Saro. Searches on the internet have proved fruitless as the company no longer exists. We did purchase a similar item from a Class 47, however, dimentionally it is different and, therefore, we can't use it. So if anybody out there can send us some pointers we would be most grateful. Please contact us via the e-mail address on this web site. Our next up-date will show the removal of the B Bank pistons and progress on body work.

During the turbo overhaul it was found necessary to remove the silencer elbow which we noticed was severely cracked and required welding to cure these cracks and the best way to do this was to remove it from the turbo. The view above shows the muck extracted from inside the turbo.

This view shows the body work below the radiato area receiving attention. Plate work had been removed by our body work specialist, Matt Thomas, also in this view you will notice the original segmental bearing lubrication point which was plated over during the 1960's modification programme. This area is waiting for the new metal work to be welded on which we have just purchased so, hopefully, our next update will show this area completed.

These views shows the unique casting from the control air pipe work from No.1 end cab, the pipe leading to this casting had severely corroded and has been replaced with a flexi hose, however, the thread on the casting is the now defunct emeto thread. Our replacment pipe was fitted with a BSP coupling so the spiggot that you see at the top of the casting is about to be machined away and replaced with an internal BSP thread. The second view shows the thread being cut.

Our two intercoolers were dismantled and the matrix inside removed with new gaskets made and the matrix meticulously overhauled and vacuum tested. One has been reassumbled as shown in this view whilst the other one awaits the refitting of the matrix. We did find during dismantling one of the turbo's that a bolt with its spacer and locking tab had fallen off the matrix and would have probably ended up causing untold damage had we not had dismantled them and cleaned them. As with the gaskets on the rebuilt free end of the power unit all gaskets are home made.

Welcome to our latest up-date, we still haven't quite hit the targets set out during the last up-date but progress on the locomotive and power unit front is still on going. This view shows the turbo after it had been cleaned and vacuumed, the propeller spins freely so we decided it was unnecessary to dismantle the unit and a straight forward clean and paint job should be done.
