These are the pistons and connecting rods removed from 9016's power unit. All of these will be re-used as they have been found to be in good condition. However, five pistons were found to be damaged beyond repair by the chemicals in the fire brigade's foam...
1865 - Photo: David Dimelow & courtesy of Michael Timms.One of the pistons removed from 9016's power unit clearly shows the corroded piston rings and the marks on the aluminium body of the piston where the chemicals from the foam have started to eat into the metal...
1864 - Photo: Michael Timms.Another of the damaged pistons stands on the work-bench at Paxmans. As can be seen, there is severe pitting on the body of the piston and around the piston rings. The con-rod is however still suitable for re-use...
1863 - Photo: David Dimelow & courtesy of Michael Timms.Another piston removed for 9016's power unit lies on the workbench at Paxmans. The body of the piston is contaminated by the chemicals in their foam, which has rendered this piston as scrap. The con-rod however, will be removed from the piston and re-used in the rebuilt power unit...
1862 - Photo: David Dimelow & courtesy of Michael Timms.This view shows one of the component trays at Paxmans. This one contains some of the end caps which hold the crankshafts in position in the power unit. Each end cap, which is an aluminium casting, has a hard metal bearing surface fitted to them. As can be seen in this picture, the end caps themselves are in good condition, but the actual bearing surfaces are showing white marks which are the eating away of the bearing itself. The end caps will be re-fitted to the power unit, but the bearing surfaces will be replaced...
1861 - Photo: David Dimelow & courtesy of Michael Timms.The three crankshafts from 9016's power unit sit on the floor at Paxman Diesels awaiting re-fitting. These were found to be undamaged in the strip down of the unit and their bearing surfaces are brightly polished and fully serviceable. These will be put back into the power unit when re-assembly starts in a few weeks time...
1860 - Photo: Michael Timms.This view shows the other end of the three crankshafts, which have been found to be in excellent condition. This end of the crankshaft is positioned at the scavenger end of the power unit. The gearwheel at the other end of each crankshaft connects to the phasing gearcase...
1859 - Photo: MAN B&W Paxman & courtesy of Michael Timms.This view shows six of the eighteen cylinder-liners removed from 9016's power unit, the others are stored below these in the racking. The reason for removing the cylinder-liners was to enable them to be 'honed-out' to ensure that once the new piston rings have been fitted to the pistons, that they will be able to bed into the cylinder-liners and not pass excessive amounts of oil. This would have been the result if new rings had been fitted to the already 'glazed' cylinder-liners.
