It uses the electronics and actuators from 8043, and the wheels from 8264.

Here is a video which explains how it works, with some basic instructions:



This model was built and refined over a period of one year, although only with some handful of hours per month.

The transmission was fairly easy to finish, but getting the boom/tilt geometry correct took a lot of trial and error. It's still not perfect, I would have preferred that it tilted further backwards in the lower boom position. But it works quite well.

The connection between the chassis and the superstructure also took some refinement. It needs to be solid, and well integrated with the transmission and boom/tilt mechanisms, to avoid a too large footprint.

Also, the weight balance was a challenge. Originally, I wanted to place the battery box further back, but the vehicle would tip backwards when accelerating. Hence, both the drive motors and the battery box were put as far forward as possible.

I like the design - so compact and neat.  The color scheme looks nice also and I like it with the 8264 Wheels.  Nice work!   :thumbup:

Very nice MOC indeed. Good work  :thumbup:
Only point of critique would be the speed of the Booms and bucket, seems a bit slow (?)

I started on one myself several times already, but I can 't quite seem to finish one :tongue:

Thanks for the comments. The instructions are not as clear as in the LEGO models you can buy in the shops, but by looking at several of the images, it should be possible to recreate it.

I would suggest taking a look at Jennifer Clark's Skid Steer Loader, as that is the only one I know of with instructions for sale.

Here's another one.

You haven't mentioned it that I saw, do you have any bricks to start with, and do you have any experience building with technic?

I have always favored the tracked variant when I built them.

Does anyone know if anyone has ever converted Jennifer Clark's Skid Steer Loader from pneumatics to PF?
