Quadrotrac

[Steinbruchsoldat]

The postman shows up every day, and the pile of "parts i need to find some room for" grows steady:

Then i continued working on the boogie axle bushings:

I eventually finished it, also tested the hydraulic oil temp gauge:

 

[Steinbruchsoldat]

Got the two pressure gauges today:

Wanted them to be illuminated, so i tried something:

Perfect:

Awesome work!

 

[Steinbruchsoldat]

Thanks...

Turned the boogie axle bushings today:

Turning plastic creates a big mess:

Finished. One missing because i screwed up. Well, it`s just $20 worth of plastics and cleaning up that mess again, right?

Parts pile is still growing:

Also got another shifter assembly to use for the transfer case:

This is going to be tight. No problem, there are only 6 hydraulic valves missing...

Do you guys think i can get the throttle working with a long cable? It`d articulate while steering, ect. I thought about building a simple drive by wire system...

Id stick with the cable. Simple, no electronics to break. I dont think it will be a problem with the articulation as long as its routed well.

 

[Steinbruchsoldat]

That`s what i think too. More electronics means more stuff that can break...

Btw., just bit the bullet and ordered some hydraulic valves. Seven to be exact... :Wow1:

7 more things to break!

Well, haven`t found out how to control hydraulics without valves? :smiley_drive:

Will have a total of 8 hydraulic valves in two circuits.

Circuit 1 is for the steering,at about 2600psi.

Circuit two consist`s of:

-tilt ram, floating
-front end loader, floating,
-winch
-front aux 1
-front aux 2
-rear aux 1
-rear aux 2

Will be run at about 3600psi.

That was in jest... Doesn't come off well in text.

But really in a hydraulic system the hoses are always the weak point.

Julian,
Drive by wire works great (Ram trucks, Toyota, Nissan) and it's certainly economical with space, but I would think you might want some redundancy so you're not stuck out in the frozen tundra some where. Cable, if you have the space, is pretty KISS and bullet proof.

Yes, but i doubt this`ll be a problem cause this machine probably won`t see many hours compared to a excavator or something like this...

Finished the first three bushings today:

Mounted both inners, so i could start with the floor:

Didn`t like it, so i started over. But i have to make the side panels first. Before i had to weld everything up that i can`t reach with the panel in place:

Put the first part in:

Didn`t have a big enough panel, so i had to put a small strip in:

 

[Steinbruchsoldat]

Started by making the left side panel today:

Then i made the left floor panel:

And the right one:

Made a cover for the winch line:

Mounted the first shifter:

And the second one:

 

[chnlisle]

Beautiful work!

 

[VanIsle_Greg]

Coming along nicely...

Getting closer now! Lots of finish welding to do...
