Today, some Eurobricks members started to report they have received the Service Pack to fix their 8043 Excavator problems.
The Service Pack includes:
- 4 new Linear Actuators.
- A set of smaller parts (4) to fix the right track problem, consisting of:
- Revised building instructions pages (41 and 45) from book 1.
As previously explained  the new LAs have an identical look to their predecessors, but could be distinguished by their new production code, located just below the orange cross hole.
According to the reported case, the code is 36X0. However I might check if this is an unique code (have my doubts), or if it will change over time as new production batches take place.
The new LAs and modification, are reported to be effective. Lower friction LAs, smoother and faster boom lift, and no more problems driving tracks.
Questions about the new LA design remain. What was changed? Has the internal screw pitch changed (meaning number of turns to run the full course)? Did the internal clutch suffered any changes? Does rod bends less when fully extended?
It should not take too long, until we get answers for at least some of these questions.
The main difficulty seems to be applying the track modifications, if you have the model previously built, as there aren't specific instructions to do it. It wouldn't be easy to the probably without dismantling a significant part of the model. As this is a building toy, it shouldn't be a problem however...
So it looks, soon we all be able to play and joy with the renewed beauty again.
In the country where I live, the new 8043 boxes are expected to arrive at stores in the middle of October.
