Service set maintenance begins with 5057

Bogie number 9 has had extensive work carried out on it prior to being fitted under mark 1 TSO number 5057.  The old axles had to be hydraulically pushed out of the horns, this was because the horns had been pushed out by a build up of rust behind them.  The horns were removed by grinding away the welds, cleaned up and then re-fitted.  This had to be done twice as the first time they weren't welded back square.
The first picture shows the replacement axle in place within the cleaned up horn guides.

A close up of the axle end and bearing.  All of the caps have been removed, the old grease cleaned out and generally cleaned up.  New cork gaskets have been used when the caps were replaced.

The reason for having to change the bogie is shown below.  These flats have been causing this bogie to thump its way down the track all season.

And flats picture 3.

5057 has been lifted and the offending bogie removed.

Whilst the bogie is out, 5057 has been lowered onto a slave bogie for safety.  This also allows the vehicle to be worked on whist the bogie is out.

Bogie number 9 is being worked on at the other end of the shed, under the lifting gantry.

When the bogie is ready to go back under the coach, the coach is lifted and the slave bogie removed.  Here Richard, Bill and Jack manoeuvre the slave off the track to allow the bogie to pass.

Bogie number 9 is then pushed into position.

This procedure was carried out six times before we got the ride height of the bogie correct.  The springs have shims at the top and bottom of varying sizes, these are added or taken away to raise or lower the ride height.  Its a frustrating task.

Above and below, the equalising beam spring removed to adjust the height.

Eventually we succeeded, here Steve finishes off with a coat of paint.

Very smart, the shock absorber will be painted blue and the bearing caps bright yellow.

At the other end bogie 30 is receiving the bearing grease treatment.

The wheel flats were thought to have been caused by a faulty brake cylinder which had seized momentarily.  Therefore both cylinders are being replaced with overhauled ones.  Here the lift table is in position  ready to lower the cylinder when released.

Cleaning the dirt off.  The door on the right of the picture is the faded paintwork as per when the vehicle came into the shed.  The panel on the left is the paintwork after cleaning up and polishing.  Its hard on the arms and a long way around the coach.

More equipment.  Two home made oil tanks for soaking the bearing pads in.

The battery bay, another area that could do with attention.

A rarity, Richard captured looking at the camera with Bill on the left
