CAT 14M Motor Grader

That looks great!
Is the outward connection of the side shift is not outwards enough, it looks like you have only relatively little movement to the right?
In the original, the brackets sit much closer to the end of the blade.
Is this a restriction because of the hydraulic cylinder?

The movement is actually made by electric motor and spindle, and that restrict the travel. The short travel (35mm both ways) annoys me too, so I´m going to change the spindle to hydraulic cylinder.

Ah yes, that makes sense. Hydraulic will be beneficial there.
Are you going for a rotary feedthrough for the blade tilt and shift?

I use a spindle drive - it works very nicely and I get a lot of travel, but dirt is an issue. I am thinking about converting to a pull-pull winch - not sure, it's just a thought at this time. But for the high quality of your model, I feel that hydraulics is the way to go.

Set with pictures

BTW, could you tell me what diameter tube you used for your blade?

The tubes is diameter 66 mm.

Ok, now I made the hydraulic cylinder for the side shift. It works much better than the earlier spindel , and it now has much more power and travel (50 mm both way).
Only drawback is that I might not be able to route the hoses inside the horizontal tube, and out in the middle I had to take them out straight from the nipples.

There is also a small video clip of the side shift, and if you wonder why there is a bucket in the picture, that´s because I took the hydr. pressure from my excavator
