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.

Small but essential items
The oil trimmings for the numerous oil reservoirs which lubricate the moving parts of the                    locomotive have be made in readiness for fitting

As the return of the boiler is imminent, attention has turned to cleaning the boiler expansion frame plates

A missing section of vacuum pipe has been located, inspected, cleaned and painted

The cab roof has been removed to facilitate fitting of the boiler and firebox and an opportunity taken to clean and paint it

Plating at the front end of the locomotive and over the steam chest has been finally secured in position

Cladding has been refitted to the rear of the cylinder casting

and to the front end
The Chassis
New wear pads have been welded to the brake beams in readiness for undertaking the last major job on the chassis - fitting the brake gear

The intermediate driving wheel brake beam has been fitted to the brake hanger and the safety chains fitted

and the rear brake beam has been similarly fitted. Pull rods, compensating links and barrel adjusters now need to be fitted before the brake blocks are attached.

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

The front tube plate showing the machined seating for the regulator box and the longitudinal stays protruding though the tube plate

                                         Inside the boiler looking towards the front tube plate

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
