Liebherr R954C
hiya,
just thought I'd start my build thread for the R954. I am building it for a friend as a fully hydraulic 1/14 scale machine. Most parts I will be making my self other than the Hyd Pump and Hyd Rams. the rest such as the Hyd motors for tracks and slew ring, Control valves and the slew joint are amongst those I will making in my shed of wonder and mistery. it's a bit of a beast at around 16 Kg and a full length at stretch being just over 1000mm. I will add the first pictrues on sunday. :) |

Nice, looking forward to this!

Re: Liebherr R954C
I can't wait to see more of this build!!!
|
Re: Liebherr R954C
Cool, more scratch built excavators! I like it!

Re: Liebherr R954C
Nice start,looking forward to this !!

Re: Liebherr R954C
Just a little more done.

Re: Liebherr R954C
A huge project and challenge!
Good luck. There's somebody building a 954 in a German forum too. Impressive. This is going to be a beast. Cheers Pip |
Re: Liebherr R954C
Thank you. At 1/14 it's on the large side. But it's going to be fully hydraulic. I think I've seen the German build. Is it with electric tracks?
|
Re: Liebherr R954C
Wow, this is going to be a monster. I read that you were going to make the hydraulic motors and valves. I'd like to see that step by step as I would like to build my own. Great start on the build.

Re: Liebherr R954C
Hi there!
I think the German build has electric tracks, planetary drives with brushless outrunners. There's a picture on the last page of the thread. How do you plan to get the hydraulic oil from the upper to the lower section of the excavator? Cheers Pip |
Re: Liebherr R954C
The transfer from body to undercarriage is done via a slew joint.
Alot of the the new parts are going to be made as the original. Its long to explain but it's the easiest part out of the 3 hyd components I'm making. I'll post pictures when I have completed it. But it's a barrel system. Bex |
Re: Liebherr R954C
Hiya,
Here you can see how the hydraulic components are being made. Hyd motor, valve block and slew joint http://i526.photobucket.com/albums/c...5/59b36af4.jpg Here is the barrel for the axial hyd motor. http://i526.photobucket.com/albums/c...5/cd40f4a1.jpg |
Re: Liebherr R954C
HMM, Pistachio nuts, graph paper,pencils. This build is getting interesting.
Oh, I forgot to mention shop built cigarettes too. |
Re: Liebherr R954C
All key components to successfully building a R954C lol
|
Re: Liebherr R954C
May I ask why you are going for an axial piston motor and not radial?
Axial machines typically have considerably higher RPMs than radial ones for a given power and hence lower torque on the shaft - are you using a gear between motor and chain wheel? |
Re: Liebherr R954C
Yeah I'm using a reduction gear box like in the real final drive.

Re: Liebherr R954C
great work so far . I'll be watching the hyd. motor build ;) my dad has a hydash pulled appart for 1 of our koerings 6605 excavators , I've been tempted to build some mini 1's . It'll be a few years yet till I get all the equipment aquired :( unless I get a brain storm :D
|
Re: Liebherr R954C
Just a little update:
The axial piston motor now has one piston. http://i526.photobucket.com/albums/c...5/87c799c2.jpg http://i526.photobucket.com/albums/c...5/b28febce.jpg It does look wonky but that's because it's right on the end of it. |
Re: Liebherr R954C
Rebekah , you are a genius :D . I've been trying to figure out how to do the ball on the end of the piston . Thats a great idea ;)
