The major news this month concerns our driving wheels. We reported last month that they had to be tested after defects had been found in one wheel. The shot-blasting required for testing purposes was completed around the end of May, and the inspection itself was completed on June 14th.
Work at West Shed continues to be limited by PRCLT’s need to allocate resources to 6233’s overhaul. However the left hand side expansion link has been successfully fitted and the inside expansion link has been removed for assessment.
There is no progress yet on the testing of the driving wheels reported in last month’s bulletin. The wheels have to be shot-blasted before the testing can be carried out and we are liaising actively with Riley and Son to get this done.
At West Shed, the motion has now had all the bushes pressed off and the condition of all components fully assessed.
Following discussions with PRCLT we have decided that using the legacy motion parts obtained for 5551 could have a hidden risk of failure. One of the radius rods has a previous repair that has weakened the part to the point of being unsuitable for further use. We will therefore be sourcing 2 new outside combination levers, 1 union link & 2 outside radius rods.
