Removing an 831 loader

[jdcollector]

I'm about to start working on my 440 ICD that I just got and need to take the 831 loader off to get to everything. Does anyone have any tips or ideas on the easiest way to take one off? Any tools that would help?

The crawler is sitting at a friends house outside and we have a couple engine hoists and that is it for lifting equipment... Any suggestions would be greatly appreciated before I go out and attempt to do it all wrong.

Thanks for the help in advance.

Well my first thought would be that you really don't need to take the entire loader off to "get to everything". You may want to take off the top boom frame with its cross bar; but you can pull the engine, and then the direction reverser, and on back to the transmission, and still have the main loader frame in place. Likewise you can remove the tracks, all of the undercarriage, and the final drives without removing the loader frame.

The parts of the loader you want to take off, are simple unbolt and remove operations. The main consideration is the hydraulic lines. I would recommend taking pictures of the routing of the lines; which ones snake through where, and which ones go over top of which other ones. Label them with tape, and maybe draw a little diagram. Drain all your hydraulic fluid first and have caps ready to put in the end of hoses and fittings. Happy wrenching. Gil

Label them with tape, and maybe draw a little diagram.

I am a BIG fan of taking lots of digital pictures, from all angles, before disassembly. It is amazing how helpful that is for reassembly, whether a truck or crawler.

Thanks for the help. I was able to pull the pins on the lifting arms and the upright to get the loader off. For some reason I was thinking that I needed to take the whole thing off. I'm glad that I did not have to though. By any chance does anyone know how big of a bucket the 831 loader has? I've heard that it was a 7/8 but not positive. Thanks again.

I think 5/8 struck, 7/8 heaped.

JD calls it a "7/8 yard bucket" in their brochure from 1959. Not sure though if they mean struck or heaped.
They filled 20 dump trucks that held 7 yards each in one hour and only used 2 gallons of fuel! (440ICD w/ 831) It was a stockpile of loose soil and they ran in 3rd gear.

That is impressive!! I have the manuals for the 440 but have not gotten a set for the 831 loader. I guess if I got them they would tell me all that information. Do they say anything about the dozer blade that you could put on the loader frame? I have heard of them but never seen them before.

Patrick,

That information comes from an advertising brochure from 1959.
This particular brochure does not show the blade attachment for the 831 loader.

Dozer blade for the 831 is 72" wide and 23" in height with a 9.5" depth of cut.
Here is some additional information for the bucket on the 831.

Pry out at ground level: 8500lbs
Bucket lift at ground level: 7000lbs
Full height lift: 3300lbs
Drop below ground level w/bucket level: 4.5"
Drop below ground level with bucket tilted 9 degrees: 9"

These all come from a Deere 831 manual dated 4-60.

Thank all of y'all for the information. The dimensions of the blade and the specs for the loader are very helpful. I will probably get the blade that I have been told about sometime after Christmas when everything settles down. I hope everyone has a wonderful and blessed Christmas and a Happy New Year!!

If your last post said that you found a blade for the 830 loader, it would be nice if you would post a picture when you get it. If anyone else knows of one for sale, I would be interested.
