Posted July 15, 201410 yr Hi there, perhaps you all know this page: Designer Han I am working on rebuilding the 8421 XL. But I got some problems with the links at the crane arm. Did somebody rebuild this one? I have to connect a special number of links and other links together. I did it like is is shown on the instructions...but my crane arm isn´t working. Perhaps you can help?!
July 15, 201410 yr I had trouble too. I think I needed to adjust both the amount of links and the placement of them (i.e. on which side of the "kingpin" link).
July 15, 201410 yr Author Yes that is my problem. I need the correct amout of the links. Couls you please count yours, nychase?
July 18, 201410 yr I'm sorry I no longer have it built to check. The action was never smooth on the boom.
