Building subframe for YFL-240 + Refurbish for my YM240D

[yanmars]

Just so there is no confusion for those looking at the photos I sent. I also have a Woods 750 3 point hitch backhoe on the Yanmars. At first it was secured with some of the 3 point arms etc. I had some concerns about breaking the tractor so I at first added that all thread rod seen in photo 8 from mid frame to the back. My father in law added that and thought it enough. It may well be as he was a bright guy but I chickened out and bought the subframe that Woods or Yanmars suggested. Since it did not interfere with the all thread rod I just left that. The 3 point arms etc. are removed but I have them in case I ever would remove the backhoe.
Times change, I got the tractor and loader and a grader blade in 1989 with under 900 hours for $3750 and the loader in 1990 (it was fairly new) for under $1500 I think.
jklColorado has talent and is fabricating a solid loader.

At that time the price was very fair for that package deal, I would have bought it too. From what I have read and seen from jkColorado's posts, yes he does appear to be very talented and I have no doubt his loader will be a solid build.

After awhile I got my loader valve from Hoye, and more importantly, a little time to mess around with it.
There was no clear position the original valve was installed on the tower, so I have the opportunity to place it where I feel most comfortable.

I eyeballed where I felt it should go, then made a plate to bolt it to. I just used some scrap 2 box tubing. I beveled the end of it just to make it look less home brewed.

The placement felt great. I had easy operation in all positions with my arm resting on the rear fender.
However, once installed and bolted down tight, I found the 吐loat function was in a weird place. Joystick far left would activate float.
Whoops.
I didn稚 feel this without the valve bolted down because there is a substantial detent that I couldn稚 get into without it locked down solid.
*****sigh****
I personally liked this position as it allowed the hydraulic lines to exit out the top making a nice east loop to the steel lines on the loader arm.
The way it痴 SUPPOSED to be forces the hydraulic lines to exit towards the engine.
Without completely starting over on the mounting arm, the only way I can remedy this is to get 90* adapters.
Looking on Hoye痴 website for the adapters I purchased, it states 菟ort from loader to -6 JIC? This isn稚 much help.
I知 guessing the proper term is 3/4 ORB to -6 jic elbow.

I知 learning hydraulics and all the nomenclature that goes along with it. Always frustrating when there are so many options.

Oh well.

I also removed all the short hoses from steel lines to the cylinders so I can have them rebuilt.
I also want to have all the cylinders rebuilt. They all seem okay, no leaks and no rust or pitting but I壇 prefer to just have them in new shape.
Anyone have any idea what it typically cost to rebuild these cylinders?

Welp, it痴 finally operational.
I still need to redo the front diagonal bracing to raise them up a bit. Right now the steering knuckle hits the brace at full lock.
And also need to fabricate the rear brace to the axle.
But on my way into work this week, I stopped by the hydraulic shop and had them build me all new hoses. Then a couple more trips to get adapters and fittings to get them all hooked up.
Man that痴 a chunk of change for 14 hoses.

Had to get creative on the elbows going into the valve because they pack them so tight together you can turn them without them hitting the ones next to it. *sigh

But tonight after picking up the last two adapters today and having the supply and return lines made, I hooked it all up, fired up the machine and wouldn稚 ya know it, it lifts and curls!
I couldn稚 be happier!
This is going to make work around the house and shop SOOOOO much easier.


It痴 certainly not fast. Maybe a higher flowing pump would remedy that?

Also need to build a bucket level gauge. I can稚 see the tip of the bucket to know when it痴 flat to the ground.
I知 used to skid steers where you can see the cutting edge of the buckets.

Considering I致e never worked with hydraulics before, I didn稚 have to remake any hoses (for not knowing the technical names and sizes of each fitting), AND nothing leaks!
I知 glad I decided to tear this all apart. Every single fitting had Teflon thread tape on them
Got all that cleared out.

I also figured I would run these cylinders for a bit to see if they actually need rebuilt.
At this point, it doesn稚 appear they do. No leaks from them either so I値l just roll with them.
If I don稚 include the cost of the tractor, only the cost of the loader, I知 about $800 all in with the loader, all new hoses, new valve and using scrap out of my pile to hook it up.
I can稚 complain much about that for the use it値l see.

The original owner still had the powder at his property.

what kind of powder is that??..

I’m afraid I can’t mention the specifics here...........

On another note, i apologize about the weird symbols and stuff in my posts.
I wrote the whole thing up, the copy it, then work on loading photos. By the time I come back to the page, everything I wrote is gone so
I paste it back with the photos inline.
When it posts it has all that weird crap anywhere they’re is a normal punctuation.
Stupid phones and forum engines

Very nice work!

I have not tried this in years so it may not be in place any longer.
Years ago in a different period of life, I had to write up reports and transfer them along with graphs, tables and excerpts from spreadsheets to a ‘server’ based system. I worked from a different location from where the server was located so I prepared my reports on my computer. Again years ago in the days of different operating systems sometimes even within the same brand if computer. (This was pre windows and very early windows days—nothing like today’s windows). All of that to set up what we worked with then, anyway there was a buried option to save files in an ascii format. It removed the special characters used by different programs to provide punctuation and other things. Somethings still needed to be edited after the transfer, but mostly it would transfer without crazy words. I quickly learned to save 2 copies of my final report. One normal for the program and one that would transfer.

A lot has changed since DOS
