Introduction: Lego 8294 Excavator Swing Mod
This instructable will show you the step by step process of how to build a custom mod to control the swing on the Lego 8294 excavator. It is quite simple. Bear with me, as this is only my second instructable.

Step 1: Disassembly
Refer to the second picture for a good look at what to take off during the disassembly process.
Step 2: Materials
The picture has them all. The V-shaped connector brick should be one that has no angle. I just used what pieces I could find.
Step 3: Assembly of the Whole Mechanism
Put the longest bar in a connector, put a 2 stud bar to connect both connectors, add the 4 stud long bar, and attach the gear.*
*Note: During assembly process, you may need to put it on it by taking it apart/dividing it into 2 or 3 sections to install it easier. I even had to take the 4 pins out that hold the whole house of the machine to the base to put it on.
The second picture is of a bracket that the axel of the mechanism must go through.
Step 4: Attaching the Bracket
All you have to do it install it between those two bars as shown.
Step 5: Attaching the Shaft
I apologize for the blurry picture. I will use the image note bar to outline what has been added on.
It has all been put together. I actually had to remove the top of the excavator from the bottom in order to get the whole thing on. Remember to slide the gear up the shaft a bit for clearance of other things below.
Step 6: Reassembly
Pic.1 Attach these pieces back the way they came, minus the warning light (far left) which should be on top of the cab with the shaft attached to it.
