In the absence of Ian Pearson, Chris Henwood has reported a very busy day on shed at Grosmont yesterday, which made for an interesting working party and a brilliant atmosphere. The presence of sizeable working parties on 44806 (on the pit) and Lucie, consisting of people of varying footplate grades as well as shed staff, meant that there was no shortage of shunter drivers, passed shunters, and senior shed staff for advice and opinion.

In Deviation Shed, there was just Neal Woods and Chris working on the J27. No work was done on the T2/Q6. The J27 was washed out earlier in the week, and its new wheel position, having returned to Deviation, meant the pistons were in a good position to allow the cylinders' inspection and for measurements to be taken. The bores appear to have suffered a slight lack of lubrication. After some physical investigation and testing, and discussions  throughout the day with Barney and colleagues, it appears previous adjustment in the mechanical lubricator deliveries may have been the cause, but also the answer. Work will continue in the shed to assess, adjust and test the system in the coming weeks. Neal completed the necessary work on the R/H valve, including cleaning the face of the cover, meaning both cylinder covers and the valve covers can be fitted on the arrival of the copper gaskets.

Chris spent the morning thoroughly cleaning the firebox and oiling the tube plate. This job is now finished. After lunch the J27 was shunted to No 1 Road pit, and the contents of the ash pan disposed. The grate and ash pan were swilled out with a hose. The J27 was then returned to No 7 Road.  The fusible plugs were also removed, and a quick 'end of day job' saw the fitting of the whistle.

Next steps are to arrange for the cold examination of the boiler by the boiler inspector. Once the NYMR has finished the work on the safety valves, the J27 will not be far away from being boxed up ready for a hot exam after the boiler inspector has been.
