Rebuilding 8421 XL problems, HELP PLEASE!

[Beeman]

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?!

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).

[Beeman]

Yes that is my problem. I need the correct amout of the links. Couls you please count yours, nychase?

I'm sorry I no longer have it built to check.

The action was never smooth on the boom.
