Now "I" Went and done it: Got me an old Hoe

[Smiles007]

Were the worn out bushings at the base of the control levers? Having trouble visualizing.... How did you nail down material type? Reason I continue to inquire: There are a couple old hoes (back hoe types) down the road that I have been tempted by... not sure if i want to buy a project of this manitude at this point....

There are 6 pivots in total for EACH lever. So it is very difficult to visualize. But yes, the bushings are in the base of the control. It is what the control levers pivot around. There are TWO in each of the 4 main controls so thats 8. Then off the lever, there is a vertical rod into another lever with a central pivot and bushings. 2 in each and one for each control, so thats another 8.

Most old backhoes are worn and sloppy. Still could be used for many, many years; just dont have super precise control with a sloppy hoe. And unless you have access to a lathe/mill, or are in good with a machine shop, it gets really expensive really quick.

Just some of the parts on this one (which I will make and save $$$) like all the pins on the backhoe. There are probabally 18-20 in total. Each with about 3 bushings. The pins are anywhere from $100-$300 EACH, and the bushings $25-100 EACH. Now this is the big pins, not the control levers, but you can see that if you wanted to replace ALL of them, it would most likely cost more than the whole machine. Which is probabally why all of the old and under ~$10k BH's are sloppy.:confused2:

Heres what I drug home yesterday:thumbsup:

Congrats looks like someone kept maintenance up on it .
Remember what the sailer said when his ship hit port "Old hoe better than no Hoe".

A little update.....

There are a total of 16 bronze bushings that were all wore out. Pretty simple. 1/2" ID, 5/8"OD and 1/2" long. I really couldnt believe CNH thinks these are worth $10.74 EACH (according to messicks website):confused2:

Same oilite bushing at mcmaster carr.......................$0.88/ea. THATS more like it:thumbsup:

Wait till you find out how much they charge for shipping that bushing... Been there done that and WON"T make that mistake again!

Got some photos of the linkages, LD?

A friend just landed a 4500 for "free". Just has to haul it 100 mi to get it
home. Sometimes, 'free' is a dangerous word.....

LD1, congrats on your new project. Looking forward to seeing pics.

Here are some pics.

I didnt take pics of everything I did, but the following are....

1st pic is the control lever. New bushing in the main pivot. And bushed the smaller hole where the adjustment rod hooks to it. These holes are "supposed" to be 5/16". But in the vertical direction, before the bushing, measured almost 1/2":confused2:

Second pic is a bushing in the rail that mounts the long rod that all the secondary levers pivot on. Those cast-iron levers also got new bushings, but no pics of them.

Third pic is new pivot pins for the control levers

Also did the following that isnt pictured:

New 1/2" long pin for the secondary levers.

Bottom end of the adjustment rods were welded shut and new holes drilled.

One of the secondary rods' ends needed welded and hew holes.

Made new short-links where the secondary rod attaches to the valve. These almost look like little chain links.

And all new short 5/16" pins. (actually going to use 5/16 shoulder bolts) as there is enough room to get on them with a wrench:thumbsup:

how is the project on the old hoe coming? Also was wondering about how the old backhoe project was coming along? Got a chance to operate my friends' JCB hoe today. .....weighs 14k lbs.... totally different monster than my little Kubota!

Havent really dont much. Been busy with it digging a basement and doing some trenching for mom and dads new house.

I did rebuild the swing pins and bushings before I took it over there.

I also managed to break the end of the dipperstick off. The bucket was just holding on my the cylinder. Had to weld that back together.

Right now, it runs and operates okay, so I dont want to tear into it too much and dump a lot of money into it just yet. But maybe oneday I will restore it to all its former glory

I was chained in the operator seat of a Ford 555 for 12 years. The thing was indistructable and did everything I demanded of it. I went on to engineering school and believed they used that tractor for another 15 years. In my opinion, Ford built an extremely good tractor/backhoe capable of doing just about anything.
