8052 container truck hook mechanism

[arik]

Hi,

I've just built 8052 from parts from other sets, mostly according to instructions. I had to change a couple of details, but nothing functional, except substituting the 24t gear with the white clutch gear.

However, when I unload and load the container from/to the truck using the clever hook mechanism, the hook doesn't get sufficiently low for easily attaching or detaching the container. It stays maybe one stud too high. If gently pressed down, it can slide under the container attachment point.

Do you have the same problem? It's not a big issue, but I've seen a YouTube video where the truck just unloads the container and then "drives" away.

I was sure there was some kind of mistake when building the truck, but I cannot spot it. The only thing I can think of is if the linear actuator behaves differently: if it only extended a couple mm longer, it would be fine. Surely the clutch gear cannot be the reason? (Now the LA internal clutch doesn't engage, but I don't think correct operation of the model would depend on that...)

If this not a common problem, maybe I should post a pic or two, if you can spot the error/reason...

Solved! Not surprisingly, it was my mistake... A misplaced half-pin that prevented the hook arm extending fully.

Thanks for the help! (I just knew that I would find the problem as soon as I posted this...)
