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.

Repairs continue in preparation for re-wheeling

Making new bushes for the T-links in the lathe. These are made from thick wall tube of the appropriate grade skimmed down on the outside to have a few thou interferance fit in theT-link hole and machined out internally back to drawing size ready for new pins.

New bushes are pushed into the T-links using the flypress. The old bushes and pins were worn oval from 80000 miles supporting the weight of the loco.

Refurbished T link ready for use in the bottom of the axle boxes. The new pins shown in an earlier posts (19th Dec and 10th Jan) fit through the top of the T link and connect the link to the axle boxes, with the bolt seen in the above picture locating in the dimple machined in the centre of the pin.
Meanwhile the leaf springs hang from a pin (yet to be made) which passes therough the buckle in the centre of the spring and the new bush in the lower end of the T-link thus connecting everything together.
