Custom hydraulics on 100
 

As many of you know, I've been working on adding hydraulics to my 100.

I'm using a GM power steering pump running off the back of the engine. To get the rotation correct the pump had to be turned around and I made a jackshaft and used 2 belts to run the pump. Right now I have the relief valve in the pump set at about 700 psi

A 2 spool valve off of a JD 317 garden tractor.

It will be mounted under the seat since there's nowhere else to mount it where it won't look awkward or be in the way.

The lift cylinder will be on the left side of the dash tower because there is not enough room on the right side with the pump there. I had to cut a 3/8"x6" slot in the tunnel for an arm to attach the cylinder to the new rock shaft.

Here is the other side of the rock shaft attached to the 3 point lift.

This is the lift bracket for my front blade. I'll have to do some work to my lift rod to clear the pump bracket.

I still need to make a clevis to attach the cylinder to the rock shaft and make the deck lift arms to weld to the rock shaft and then finish welding everything together. Routing the hoses and trying to make it look clean may be the hardest part of this project. There isn't much room to run the hoses inside the frame.

Great job, Adam! Thanks for sharing your pics. :ThumbsUp:

Thanks guys.

Made a clevis for the cylinder. The end of the rod has been broken off and welded back on so I will try to clean up the weld and make it look a little better. At least they welded it back on straight.

Mounted the valve under the seat and started plumbing it. Need to make the hoses from the valve to the lift cylinder yet. I'd like to add a filter to the return line if I can find a small one.

New rock shaft. Need to make the pins for the deck lift arms and finish welding it.

Started making the levers for the valve. Have to make a bracket for them to mount to and pivot on. They're just mocked up for now.

That is some mighty fine work!

OK - I have the PS pump, can you fabricate the rest? :beer2: That looks great, I'd love to do that to my 70 once I get it back together.

Thanks. I made the pullies.

Found the filter I want to use. It's an inline transmission/ power steering filter. I'll have to see if any of the local parts stores carry them.

Got the hydraulics going today. The speed is about perfect. It takes right at 1 second to go full stroke with the engine running about 1/2 throttle. Put on my rear blade and it had no problem lifting it. I still need to finish welding the front mount for the cylinder before I try to lift too much weight with it. Going to make a guard for the left side to cover the clevis and lift arm. I'd hate to get my leg pinched by it. Then finish tying up the hoses and add a filter. I found out Autozone sells an inline power steering filter that should work perfect. I plan on running lines to the front and back with quick connects for the other spool of the valve. I'll get some more pics this weekend.

Looking forward to your pics, Adam. :ThumbsUp:

Great job Adam!:ThumbsUp: But.....................:WWP:

great job, just gotta ask whats the foot pedal for on right side for

That's the brake pedal. I seperated the brake from the clutch pedal. Here's a thread about it: http://onlycubcadets.net/forum/showthread.php?t=1746

I put on the front blade and tried out the hydraulics. With the front blade and carry-all on it had no problem lifting it even with me standing on the carry-all. I still want to throw some weight in the carry-all and see how much it will lift. Now, on to the pics.

Here's the cylinder in the lowered position.

Here it is raised.

The valve. I originally had the pressure and return lines hooked up backwards and was scratching my head trying to figure out what was wrong. Once I figured it out I felt like an idiot.:bash2: The valve is labeled.

The levers.

The lines at the pump. I added a piece of R/C car fuel line to the vent hole on top of the cap on the pump. When I put the valve into float and droppped the lift it would shoot a mist of oil out the vent and all over the tractor........and me.

The offset I added to the lift rod to clear the pump mount and brake pedal.

I put the floorjack under the sleeve hitch and the hydraulics lifted the rear of the tractor easily. For those pitstop tire changes.:biggrin2.gif:

Great job, Adam! I like the way you did the hydraulics on the 100. :beerchug:

Tested out the lifting capacity of the 3 point today. I put 240# (4 60# sand bags) on the carrier and it lifted it with just a slight strain on the engine. That was just a little above idle. The front end was really light.

I also made up a guard to cover up the lift cylinder rod and rock shaft arm.

Scott,
I thought about doing something like that but that was the longest piece of hose I had so it's just temporary for now.

:ThumbsUp:Great job Adam!

I found out that my pullies weren't aligned good enough and it caused the belt between the pump and jack shaft to roll over and start slipping. I pulled off the pump and brackets and did a little adjusting/ bending of the mounting brackets. Now, the pullies are aligned much better. Just need to pick up a new belt.

I had the grader blade on it today trying to rip out some chunks of concrete sticking up in my back yard. The hydraulics put out enough down pressure that I could feel the back of the tractor raise up slightly when I push down with the blade. That was until the belt started slipping.

I am working on hydraulics for my 125 and I really like your setup. On your valve, what do the 2 levers do? Is one to raise and the other to lower the implement? I always thought that one lever would raise and lower but Im not familiar with the JD spool valve. Im new to hydraulics and I want to be sure that when I attempt this I dont start hooking up hoses wrong.

The lever on the right controls one spool of the valve for the lift cylinder for the deck, 3 point, and snow blade. The other lever controls the other spool of the valve. It will be plumbed to quick connects on the front and rear to run the power angle on my snow blade and any hydraulic attachments I may want to run on the back.

I've got the angle cylinder mounted to the front blade. It's 1.50" bore x 7" stroke. The front quick connects are mounted too. I need to plumb the quick connects to the valve and make a couple hoses for the cylinder and then I'll be able to try it out.

Awesome job, Adam! I've really enjoyed this thread! :ThumbsUp:

Great job on your hydraulics!!! I can't wait to see more pictures.....:ThumbsUp:

Got the rest of the hydraulics plumbed. The power angle works great. I just need to anchor the lines in a few places and then take them off and shoot some paint on them. I added a set of quick connects on the rear too.

Nice job, Adam!

Your hydraulics, and everything else you have made are GREAT! Keep up the great work! :ThumbsUp:

Thanks everyone.

Well............I think you have completed this project, so isn't it time for some action pics?:biggrin2.gif:

Kewlll!

Your hydraulic installation looks great, better than factory.
I have been gathering parts to do something very similiar on my 100.

I have a question, how did you adjust the pressure on the power steerin pump?

Beautiful work, true craftsmanship;

CadetFarmer

Thanks cadetfarmer.
I adjusted the pressure by shimming the relief valve in the pump. The shims go between the end cap and piston housing. Adding more shims reduces the pressure while removing shims increases pressure. The relief valve is located behind the fitting that the pressure line screws into.

Cylinder
 

Were did you purchase your cylinder from? and what pressure are you using to the cylinder?

I got the cylinder from work. It's an old used Parker cylinder that was being thrown out. The mounts on it were wrong so I had to cut them off and weld on the correct mount.

Hi Adam , I am really likin' the bracket you made for the clutch arm to pivot on , would you make another to sell ?? Thanks , Darrell

Good eye Darrell. I'm actually going to be making another one for my 126 so I'll try to make an extra one for you.

LMK on the price , i might take more than one.

dgnewell@centurytel.net

You do DARN FINE WORK! Very nice! You going to paint the new steel yellow to match the tractor or white?

You should be proud of that set up, lots of hard work went into it. Very much worth it though!!

:ThumbsUp:

Excellent work & craftsmanship Adam! Definatly professional grade stuff. I hope you don't mind if some of us use your projects as templates for something that we wish to do to our own Cubs. I'd like to do both the separate brake pedal/control & a hydraulic setup somewhat similiar to what you fabbed up on your 100. Not trying to be a copy-cat, but both were killer ideas. Thanks for all of the pictures & info. :ThumbsUp:

Thanks. It was a lot of work but it will really pay off this winter plowing snow. I plan on painting everything yellow. Once I get everything painted and add the filter, this project will be done.

If you have any questions or need any dimensions feel free to ask. I'll help if I can.

steel lines
 

IHinIN;
Where, how, or what, did you use to come up with steel hydraulic lines?
