The damaged connecting rod on the original 08 was the link rod from the drive wheels under the cab on one side only, so with a bit of careful measuring i found that the front connecting rod is the same length as the damaged one. I undid the crank pin on the front wheel, rotated the connecting rod and fitted the back crank pin. The loco now runs smoothly minus a front connecting rod on one side, the good side driving the front wheel set. If any one asks what is the problem, the loco is on light duties awaiting spares
