CAT 374D L

Beautiful work Ari. Build of the year winner again for sure! I'm really looking forward to see it digging some dirt.

Incredible work on this machine. The build quality and detail is just over the top!

Don't ever paint it...just clear coat everything and leave it bare.

THE best build I have seen so far on all forums !

Thanks guys for the nice words

I got the fourth block to the valve assembly and made some more work with hoses

[RCP57]

So what is the plan for the fourth valve? Top secret?

[Snochaser]

Hi-flow for a mulching head? Eh?

[Hemi1966]

I actually have no plans for the extra valve yet, it's just easier to put it there at this stage

[RCP57]

Sure keep it a secret!

[Lil Giants]

Add a couple more "dummy" hyd lines for electrical accessories, like remote quick-tach coupler and/or screening bucket.

Amazing work, looking at your pump drive is it belt driven? if so what ratio and motor are you running?

[Espeefan]

Wow! Simply awesome. Everything is so clean, so well designed, and so scale, it's just unbelievable! I've truly gotten my scale model fix for today! It should last me the rest of the week.

[Hemi1966]

I got all the hydraulics and batteries (two 3S 8000 mAh lipos) stuffed inside the 374 and made a little demo video
Next I might go and dig a few holes in the garden

Beautiful! It runs as nice as it looks! Looking forward to seeing it digging in some dirt.

That is one of the greatest scale models I have ever seen have you though of making a quick coupler for it and additional attachments?'

[Hemi1966]

Thanks guys for your nice words

I made another video with some load in the bucket (as Joe hoped), and move all the cylinders at the same time to show the speed of the hydraulics.
It is not too fast, but I can live with that

I'm not sure what is the best rpm for the pump, and I haven't been able to measure the rpm mine runs. I have this motor running the pump with about 3:1 reduction

It starts to produce 10 bars at very low rpm, the max pressure is set to 30 bar now.

I dug my first ditch with the 374
It work pretty much as I expected, but the operator still has lot to learn
I will make a video of it later.

I think the speed is perfect!

[jazza]

I think hydraulic speed is ok , by the way Ari can you show me your cnc tool it's made a perfect job with your best skill.

Hi Ari! You have created an incredible model so far and I believe to share the same thoughts as everybody also in the forum. You are going to finish it at its best just the way you do every time. You are very talented men and always adding extra star to the forum. The speed is just perfect, it’s a big machine and as that, it`s suppose to have more power than speed and you already have it. I do have question dough. Do you have plans to make it just for you as a hobby or planning to produce it so we can have that pleasure too? Thanks for sharing your talents and hoping that you have lots of enjoyment with this unique machine of yours.
