Den här helgen hade arbetena på Hamra kommit så långt att det var dags att sänka ner loket på sina hjulaxlar, loket har stått uppallat sedan hösten 2014.
Now the work with our Mallet locomotive Hamra (O&K 1902) had come so far that it was time to put down the locomotive on its axles. Hamra has been lifted since autumn 2014 for a complete overhaul of the axle boxes, the horn guides, new horn guide wedges as well as on many other thing as the brake “meccano”. The lowering of the locomotive was quite tricky as it was a lot of guidances, now with tighter tolerances, to fit at the same time. But all went well and all the new parts did fit smoothly.
Först måste axelboxarna monteras på hjulaxlarna med nya smörjdynor och nya vekar sättas in i smörjrören i överboxen.
Nedan finns 3 timelapse-videos från sänkningen av Hamra ner på hjulaxlarna
