7820 Dinmore Manor - The Blog

This blog will follow the heavy overhaul of 7820 through to its return to steam. The chassis is being overhauled at Tyseley Locomotive Works whilst the boiler is being overhauled at Ian Riley's workshops.
We are working hard every weekend to bring together the hundreds of small pieces that require refurbishing to get the loco back into working order. Follow us to keep up todate with the weekly progress and who knows if you like the look of what you see you may even be tempted to join us and help put 7820 back in action.

The Missing Link - the Boiler
The new tube plate bolted in position at Riley and Son's works at Bury

This view of the back of the firebox shows the substantial section of plating that has been renewed to include the fire hole door aperture, the double row of rivets at the bottom being where the foundation ring, which separates the inner firebox from the outer, has been installed. The mounting flanges have been faced and blanked off in readiness for testing. The bosses welded to the corners of the firebox will one day hold the brass washout plugs

Substantial re-plating has been necessary on the lower section of the outer which is normally inaccessible as it is between the frames. The horizontal row of studs will carry the firebox support and expansion plates.

The Manor class locomotives have a unique throat plate that slopes back from the flange on the boiler to the foundation ring which allows clearance for the driving axle of the centre coupled wheels. The throat plate was renewed in its entirety and was formed at Tyseley Locomotive Works and delivered to Bury for fitting.

A bottle end, which screws into the rear tube plate, has been welded to the large tube which
                                                     will carry the superheater elements

The regulator box has had the face which mates to the tube plate re-machined.
MEANWHILE back at Tyseley
The side rods and connecting rods have been re-bushed and fitted to the loco, the cross heads have been coupled up, the pump arm fitted and connected to the pump ram
The chassis has been moved to covered accommodation around the turntable to allow a variety of tasks to be completed prior to arrival of the boiler

The steam pipes from the superheater header to the valve chest are being cleaned and inspected.
Now having arrived on site at Tyseley, the firebox and boiler cladding are stored in readiness for the return of the boiler
