Re: CAT 374D L

Finally got the tracks done:eek::eek:
They look little too wide to my eye so I probably will cut about 10mm off of them.

Re: CAT 374D L

How wide did you say they were? Maybe you should just give these ones to me and make yourself a new narrower set...Oh, I may need you to make just a few extras though to fit my Volvo....:p

They look great to me... Maybe your machine is set up to run on softer ground that's all...:cool:

Re: CAT 374D L

Really a nice build, What CAM program and what controler program(as mach3) do you use?
I have to get more time on my cnc and cam/cad, it´s wery inspiring to watch your builds.

How many small bolts are going to be needed in total? 2000+

Re: CAT 374D L

While your tracks might not be prototypical, they look great on the suspension. Larger footprint will help when you get it in the dirt:D Your work is just amazing:eek:

I think the width looks good on there

Re: CAT 374D L

Leave the track pads alone! Unless you want the narrow quarry look.
Great start!

Cheer's, Neil.

Re: CAT 374D L

You can't change Ari's mind, he's a perfectionist!

Great job on the tracks, I have made some tracks too in my life and I know how long these little a**holes take time.

Oh and spend less time in forum and more in garage, everybody want to see new updates :p

Re: CAT 374D L

Awesome work on the stick and your undercarriage! Speaking of track pads. How long are your track pads?

64.25mm sounds good. That's after the 900mm(35inch) track pads scaled down? That's what I'm doing and added just a little more. The track pads I made are 66.00mm wide and 19.70mm long. After the 900mm pads for my 390.

Do you know the actual size of a 900mm width track pad for a 374? Length wise? Is it the same between 374 and 390?

Thanks
Jeff

I made mine wider, they are actually 80mm wide:eek:. I don't like the look of an large excavator that has narrow tracks:)
But seriously, I might cut them shorter later.
I've seen pictures of 374 that has maybe over 1 meter wide pads

I don't know the exact lenght of the pad, but mine are 20mm long.

Re: CAT 374D L

Everything is looking like it's coming together nicely. As far as the track width; It would depend on what the machine is going to be working on. Narrow tracks shorter frames for hard rock where no flotation is needed.

Re: CAT 374D L

I Know the 385 ( which I'm building (2)) are 900mm (36")and 750mm (30") I'm making my shoes @ 64.25mm x about 19-20 mm .75" . I read somewhere that the 390 is just a renumbered 385 with a few added HP , etc

Re: CAT 374D L

That looks very nice!

I would go for a little narrower track pads, other then that its a piece of art!
