I have delt with this soil for over 30 yrs. Oddly, it'll stay almost vertical IF it doesn't get really saturated as it did last year. There are road cuts on the main highway that are 20-30' high and near vertical that have been there for years. I don't own the field above the shop so I can't do anyt...

This is looking at the E end of the shop (my office). When the flood started, I had to beat about 4' of rock out of here to get the excavator around this corner to help relieve it. The rock was within 3' of the corner. I had to dig the slump out of here three times. I dug a trench from here out over...

I am a geological engineer, and one of the primary cause of a slope failure like that you describe is the saturation of the head of a slope (it adds weight and lubricates the slip plane). Additional of drain tile is a good idea to mitigate this; I would make sure to install it well up on the slope t...

Sounds like you will need to dig a little further into the mountain again. With that high of a wall, isn't it likley to slump again? Post some pics, I would love to see the project. Lavoy Yes, it will. I'm planning on at least 3 years for it to get the point where it's done moving. Around half of i...

Almost..... :lol: :lol: Last winter we had an extreme rain/snow period. It super saturated the hill (mountain) behind my shop and it finally let go. It came down along the entire back of my shop (100'). Luckily, my shop has a 4' concrete stem wall back there. It came up over it onto the tin in a few...

Well, I got one set from JD to take a look. :shock: Looks like a bit out of my ability/equipment. :oops: :oops: :oops: For those intested: Pins: heat treated/hardened and ground to size. Approx 50-55 or so hardness. .004 or so over 1" Bushings: heat treated/hardened and ground to size (outside only ...

Since the tracks (pins and bushings) are 110% worn, I am planning on turning them. But... also thought about new pins and bushings. Seems no after market types are avilable so I called good old JD. :shock: :shock: :shock: :shock: :shock: :shock: :shock: :shock: $2100 in parts plus installation. I di...

When turning the pins and bushings should the master link pin and bushing be replaced with new??

It may not be "factory", but could the heavy rubber bumper pads used on loading docks be adapted? I've seen them used on the big steel wheeled old timers for parade/show use. I don't know if they could be bolted right over the regular track or not. Machine the bumper to profile and drill it. It woul...

In the winter, I have the time to make a set.

The question is, what is the material and how hard??

Gus

Looks like turning is the only option right now!! :roll: At least the tracks are one of the "easy" things to work on. Nothing else to remove first. -------------------------------------------------------------------------------------- What would it take to make pins and bushings??? Is this a viable ...

I can't get the track real tight but it appears near 100% worn. What will turning the pins do besides shorten the track?? Will I get some added time? A track thrower? OR, just a waste of money?

Like I said, very limited use, but I don't want a continued problem either.

At what point is it worth it?? I will have the tracks off later this month. I haven't done any measuring but I can feel wear. The sprockets look good so no problems there. The local Cat shop will turn them for $450.00. Is it worth it? The 420 will only be used for spring cleaning on a couple of logg...

Thanks

I'm about to bring my 420 into the shop and do exactly what you're doing. I think you've saved me a lot of work.....

That stupid that was setting was :shock: :lol: :lol: temporary, VERY temporary :lol: :lol: I had originally talked to the Son of the owner about the loader 420. Yesterday I stopped for a close look and to talk to the actual owner. The tractor IS all there......I think.......hard to say really. The t...
