Jim, any luck on the equipment search? --Cavin

Hello Cavein:

Yes, I believe we're onto a couple of units. Checking out a Cat D8H dozer and also a Cat 345B L excavator. I hope they both check out clean. I'll let you know with Pix. Neither one will win a beauty contest but sanding and paint can take care of that aspect. Most important is the mechanical condition.

Hi Jim.
Got a pic of the R series D8 last week when I went to see it settling in its current job.
It's easy to rip,but it needs to be ripped 4 times crosswise to turn the sandstone to dust.It's then pushed from the back up and over the spoil pile,then over the face to 2 Cat 966 Shovels.
This effectively means the D8 is double handling the spoil
Which ensures it gets well munched up.
Most jobs we do elsewhere with the D8's require us just to rip and push down hill to a crusher instead.

There is a D9H for sale in Northern California. It appeared to be in decent shape. Its not smog compliant so they want to get rid of of it. Nevada has some really abrasive rock in places. Make sure the liners and other wear metals are in good condition. Buy some extra ripper shanks. You will need them.

Hello, Truckdoctor:

How do I find it? Where did you see it listed?

Thank you for letting me know.

Hello, Nicky!

Great picture of your Cat with the shank buried down and snugged up tight. I can see why a single tine is so effective - directing all the power into one location. That sand is murder on the metal. A good washing back in the yard will take care of that.

Good to hear from you, Nicky!

I did not remember the ad correctly. It's a D9G. It's in the SF Bay Craigslist. Search Caterpillar. It has been for sale for a while.

Hey Truckdoctor:

I got over to see the D9G today. Solid unit and clean. Not abused. One hydraulic leak in a ripper cylinder but that can be fixed. Undercarriage good but pads are average.

Help:

So I need some help identifying an auger I bought today. Runs like a Swiss watch and everything works. Nothing that a good shop sanding and a coat of Emron won't fix. I crawled all over this machine looking for a name plate. Nyet. Nada. Nothing. Not squat. Just a lot of old yellow paint.

It's got a 4-cylinder Detroit Diesel with a turbo. The mast is 14 feet high when raised. It has 4-wheel drive and 4-wheel steering. Built like a Nazi War Wagon. Serious 1/4 - inch steel fenders. Hydraulic hoses are so large that they could pass for fire hoses!

Who made it? What is it called? What is it ????? Is it an alien life form? My wife wants to know so she can put a billboard up along the freeway making fun of her husband.

Kindest Regards,
Jim Mitchell

Did you ever hear the Thomas Edison quote about when he invested in an iron mine and how he "threw a million dollars in that hole and never even heard it hit the bottom". Well these days a million dollars in the mining game doesn't go very far so I'm sure that auger will do just fine.

Mike, I have approximately 50+ acres of alluvium. It ranges from 5 feet to as much as 38 feet down to bedrock. Sample, sample, sample. I want to auger down, find out what is underneath by running the drill tailings through a trommel wash plant before I go digging up a huge patch of God's earth.

Thomas Edison was an optimist! Good quote. Yes, the price of admission is steep and the results are not guaranteed.

Does anyone recognize this drill / auger? Who was the manufacturer? What was it called??????

That's what I kinda figured. It should work well for that. After a while you'll probably need to add buildup and hard rod to the auger flight edges. Are the cutting edges changeable or will they also need buildup and hard rod? With auger you could drill down a couple of feet, stop the auger, pull it out, collect a sample off the flights. Drill down another 2 feet and repeat to get samples from different depths and keep a log of each hole's samples and in the end have a cross section of whats under the area you going to mine.
As for the make of it, if it's homemade they did a good job!!

Hi again, Mike:

I'm trying to find out the make and model so that I can go on a search for manuals. It is not homemade. I saw one just like it years and years ago. It was working in a rock quarry drilling blast holes.

I'm no more a drilling expert than I am anything else. I thought to invest in a bunch of Kelly bars (extensions) so that I can keep going deeper and deeper. The auger on it right now is for dirt - not for rock or compacted soil. I am getting a bid to make a 24" auger with advanced "dragon tooth" carbide teeth which are superlative to the standard bullet carbide teeth. Your description of going a few feet at a time and sampling is precisely how I thought to proceed. With a 24-inch footprint, that will provide a good sampling hole.

It has a 2.5 inch hex driver shaft. I am trying to reverse engineer the operating PSI from the size of the drive shaft.

Kindest Regards,
Jim Mitchell

It looks like that drill has Coleman axles under it. You should be able to find a larger auger that would fit that kelly bar. Measure it and check around. I'll bet it is a common size. Changing the cutting edge on those is easy. I've replaced several cutting edges on augers and it doesn't take long.

Passionhawk1 · Mar 4, 2017

So Truckdoctor . . . . I should look under "Coleman"? Would Coleman perhaps be the manufacturer?

I looked at the flights and they are "hardened". The bits on the end? Well, two bits are screwed onto the end with screws - literally. The whole cutting edge on the bottom was welded onto the end of the shaft. I see no easy way to remove the bits and add a whole new cutting head.

The Kelly Bar measures 2.5 inches on each flat side of the hex. You are saying to look around for a used auger that has a hex coupling that is 2.5 inches? I really would like to drill these holes with a 24" auger so that I get a really good sample. The auger on the drill is only 10-inches wide.

Kindest Regards,
Jim Mitchell

If you add kelly bars without auger flights, there's a good chance after you get a bunch of cuttings in the hole above the auger you won't be able to pull it up unless you plan to trip in and out a lot to get the incremental samples. IMO a 10" auger will get you a representative sample. If you increase the diameter 2 1/2 times it will require a lot more horsepower and subject the machine to lot more stress. From what you describe of your needs of eqpt. to excavate this material I think the auger is going to struggle anyway. I'm not being pessimistic, just trying to see realities.
