D2 Cat

I use a 12 volts baterie for start the poney startor 6 volts with no probleme

get a j series operators manual, understand all the levers and when to use them, 12 volts is ok as long as the pony starts somewhat soon, the more u crank with the more ur going to heat it up and burn it out. good luck.

Thanks for the response I have noticed that when talking about their machines the forum says D47u is the 7u the first digits of the serial number?

That's correct. Looks like you have a 3J series (early version D2 with narrow, 40" track width). The later version is the "U" series. Starting and operating instructions are basically the same between the J and U series but Parts are different. Ebay is a good place to find manuals, they come up often (just search "caterpillar d2"). Also, reprint manuals are available too.

The difference between the J and U series is that the U series engine is a little more powerful (32hp J series, 38hp U series) and the air cleaner was moved to the firewall, just ahead of the seat.

There have been several posts here on the BB about Starting Procedures, you can search for them here too. Not hard to get one of these old things going but does take some knowledge. You don't need a key that way!!

Hello, I am in SD and I have 2 5u machines. If you need to see one in action or take a look at parts of it let me know. Also, Jim Zimmerman in orchard Iowa has J parts machines. I saw a few of them there just a couple months back.

Welcome & Good luck!

Jamie,
We will have to make plans to meet sometime in the spring I sometimes take I 90 to Hwy 81 south when I need to go to Crofton Nebraska for tractor parts. My D2 3J lives between Omaha and Lincoln on the farm you would be a little out of the way but well worth the experience. How does one know what the weight of this machine might be without running it across the scales first? It does have an aftermarket blade on it and a canopy which I believe is also aftermarket. I do have a 31 foot tandem dully goose neck trailer for hauling large round bails which I am sure would handle the little machine just a little overkill but I would still like to have an approximate weight first so I don’t break or bend things.
Thanks for the wealth of information.

Sounds good to me. I see snow in the forecast this week so I've got most of my stuff tucked away for the winter. Both of mine should be ready by April though. I just got the paint on the second one a couple weeks ago. You are the first person I've talked to in this area. If you hear of any shows or gatherings around here, please let me know.

I think my machines weigh 6500#. I think the blade, pump and mounting hardware add another 2500#. I've never had them on a scale though. I have a tilt bed tandem that I use for my skid loader and D2s. I travel the four state area here and any time I stop at the scales they just wave me through. I should stop at that Flying J on the corner of I-90 and I-29 some time just to figure it out...But I haven't yet.

Attached is the first one I did. The before photo is the day of the sale. The after photo was last spring.

Booth,
what I like about your pictures are that the engine has a nice layer of oil on it, meaning it's probably not suffering much from rust. I also like that the blade pump is on the front; this means that you have hydraulic action whether the clutch is engaged or not - my 3J has the pump on the back so it stops turning when I disengage the main clutch. Once you've been shown how to start it, you'll be in good shape. I hope you and Jamie catch up soon to take a look at it.
Cheers,
Neil.
