To remove the front dampers, the nut and bolt connecting the upper end of the front axis beam and plate is undone and the nut connecting them to the lower torsion arm stud is removed, and the lower end is installed first during replacement. Rear dampers are also fixed, the upper end being fixed by a bolt into a captive nut in the bracket connecting the side frames, and a lock washer being on each side of the bush, the lower end being fixed by a nut and a bolt, through a lug, on the rear wheel bearing housing. There is a danger of the mounting stud being worn when checking the shock absorber bushes on one of the front damper mounts; rusty threads can break open when trying to unscrew the nut, which means that it will need to be cut off, drilled out and reamed to take a larger replacement pin. The dampers are to be examined by taking them vertically, and fully opening and closing, making sure they offer firm constant resistance in all directions through which the piston travels, and that they offer equal resistance in both directions; any tight or free spots indicate a failure of internal seals, and must be replaced, but minor amounts of oil may not indicate failure.
