Also at the works of K D Flavell the loco side bearers that stop excessive rolling of the loco by contacting the bogie side bearers. One was cracked and this has now been repaired. However both side bearers have been examined.

The worn tapped holes in the footplate angles that the streamlining is fastened to are being welded up. They will then be dressed and the holes remade.

One of the side bearer plates added later in the life of the bogie. Two of the countersunk screws had to be replaced as they were life expired. The new screws are made with a reduced section just above the countersink so that when sufficient torque is applied the head it breaks off. The centre sheared section will be ground down.

The underside of the footplating has been finished in gloss paint. Not an easy or pleasant job to paint over your head for hours, so well done to the Painting Team.

The loco bogie side bearer brackets were returned to York this week. The right side was cracked and this has been repaired.

The underside of the loco bogie stretcher was di-pen inspected this week. No faults were found. In this view the leading right hand underside of the stretcher can be seen with the vertical row of bolts that hold the front of the outside cylinder on to the frames.

The mud hole doors from 60007's boiler were in store at Grosmont having been removed from the boiler when the loco came out of traffic in 2015. They have now been moved to York. They will be cleaned up and sent to Llangollen for refurbishment and fitting to the boiler.

The front buffer housings were were put back on the front bufferbeam this week.
Photograph: Darrin Crone.

New rivets have been fitted to the leading brake cylinder loco stretcher. This is the right hand side where three new rivets have been fitted. Similarly the left hand has required three new rivets. By the appearance of the frames in this area this is a job that has been carried out a number of times in the locos history.
Photograph: Darrin Crone.

The regulator stuffing box faces have been re-machined and the pad that locates the regulator rod pin machined to give the correct offset. The finish and fit is superb.
Photograph: Darrin Crone.

New bolts have been fitted to the regulator support beam, one just visible in the photo. The long regulator valve hanger bolts are laid on the valve with a cut off old bolt still in the support beam to indicate its position, though the bolt is screwed in to the other side of the beam when fitted.
Photograph: Darrin Crone.

New bolts have been fitted to the joint between the saddle casting and the middle cylinder casting, the culmination of a considerable amount of work in preparing the casting surfaces.

When the new valve liners are put in the steam chests they will be held in place by screws passing through the clamp plates made this week.
Photograph: Darrin Crone.

To position the liners accurately they can be turned in the steam chest by the special tool made this week. It is important that their radial position is accurately located so that the gaps in the valve rings run over the bridges between the ports and not over the port openings.

With cooled nitrogen evaporating from the surface the first of the new valve liners is put into place by the specialist contractors this morning. To fit the liners into the valves, they were contracted by cooling with liquid nitrogen which ensured a tight fit when they expanded back to normal temperature.

The right trailing valve liner in position shortly after fitting. It is still cold enough to freeze condensation on its surface. The liner is held securely in place with clamps and at the bottom of the liner a notch can be seen in the front face. This is to allow accurate alignment against marks on the steam chest casting.

As soon as the liners were fitted and their location checked the right hand leading sandbox was mounted on the frames.

Not mentioned in the report but we have obtained a new spiral spring for the reversing shaft as the original, furthest from the camera, was broken. The new spring requires work to fit the existing mounting bolt. This work is well advanced.

Work progresses on the superheater at the works of K D Flavell. The top flange that the anti-vacuum valve has now been welded in position and is being skimmed.

Also at the works of K D Flavell are the loco leading brake cylinders for the refurbishment of the mounting trunnions. The photograph shows a trunnion that has been skimmed to return it to round with its sleeve in front. The sleeve will be heated and slid on. When cooled in position it will be an interference fit.

The right and middle piston valves are to be dismantled so that the valve heads can be machined and repositioned on the valve spindles to match the position of the ports in the new valve liners. A start has been made by moving them in to a location where they can be more easily worked on. The split pins against the valve head nuts have been removed.

There are three circular bearing plates that sit on the top of the bogie. These have been cleaned and inspected for damage and wear. It has been decided that these discs will require replacement.

Steady progress is being made with the wheelsets. They have now been thoroughly cleaned of the grease and wax put on them to protect them during their repairs and primer is now being applied.

The pegs that prevent the rotation of the rings in the valve heads have been drilled out this week. This has to be done very carefully and requires accurate setting up to ensure no damage to the valve head as they are to be reused.

The leading vacuum cylinder centre bearing bracket was put in its correct position this week and the mounting holes drilled to suit. It was then removed for painting. Here it is on the painting bench.

The bottom of the tender sump was cut out this week and the flange in the plate recovered. The flange can be seen inside. New plate will be welded in and the old flange re-used.
