8 speed hydraulics addon

[Goldnboy 959]

Well today's  the day that I got started on this project.  I spend some time acquiring many of the parts for this. On 12/18 I picked  up the final major item from @richmondred01. I figured that my K181S was under powered  to run this PTO setup so I decided to increase HP.

 

I acquired a K321 fuel tank bracket setup, starter generator brackets from a WH 953, starter generator  brackets, from a MF10, a type II power steering  pump, and hold your breath a oil reservoir  from a JD 214 (as you can tell the color just had to go). I also have a C160 hydraulic cylinder, control valve, and rockshaft that I acquired earlier as well which should be a direct fit assembly. 

 

Now I need to acquire a PTO shaft for the front flywheel, to run a pulley for the pump. (If anyone  has these and would like to part with let me know)

 

Here is my beginning mock up.

 

I am waiting  for some Kohler head studs to arrive, and need to determine how to align and hook the oil reservoir to the pump. I forgot to mention I have checked my max height  that I can raise the reservoir to is 19.5".

Quite a rig!

 

Nicely done so far.

I have a similar set up on my Raider 12. I used a Hien Werner hydraulic pump on mine.

 

I do not know your skills or your availability to a machinist but here is how the pulley is mounted to my fly wheel. Start with a rod coupling nut. You will need one the same size & thread pitch as the fly wheel nut. Partially thread a bolt into one end of the coupling nut and weld the two together. Cut the head of the bolt off & turn the rest of exposed bolt down to 1/2". This will allow you to mount a pulley with a 1/2" I.D, on the the nut. Last measure the length of the crank shaft sticking out past the flywheel. Turn the other end of the nut down so the the depth of the hole will come close to the crank shaft but not bottom out on it.

 

Example of a rod coupling nut.

I've used a power steering pump for this purpose and it has been lifting implements for years. Sure beats jerking on a long lever.

What did you use to control the flow?  Just a standard WH type spool valve?

[Cvans 1,009]

Just single spool Charlyn valve I had laying around. The lift on the back of the tractor uses a lift cylinder from a Ford garden tractor.

Nice Rig.

 

looks like a Bosch Power steering pump.

if so, than that pump supports your System with 90 -110Bar of Hydraulic pressure.

You have to take care, the spinning direction is right.

 

I tried on my first tries the same pump, but i found out it must spun in opposite direction on my system compared to Engine rotation.

 

Not sure, how the kohler spins, but before i would try a test with some oil dribbs in the suction on rear for a pre test. Few dribbs are enough to see if spinning direction is the same.

 

in right spinning direction oil dribbs will come out on the high pressure side ( open before test) 

( and please be carefully, 90Bar is a lot of Pressure) 

you can spin it easily with a finger to see if spinning direction is right.

 

otherwise simply rotate the pump at 180 deg. What is on your setup easy possible.

 

 

[Cvans 1,009]

Nice neat setup your putting together. 

Don't remember the brand of pump but I do remember it came out of a Nissan. Wanted something with a metal reservoir so I could tap into it and also enlarge it if necessary. As it turns out it has enough capacity. Flea-bay purchase.

I like your belt guard  what is the from or did you fabricate  your own. The belt guard  I will tackle  at the end and I assume  it will be something  done from cardboard  at first for a mock up.

Thank you, I fabricated it myself.

[Goldnboy 959]

Today I finished  fabricating the front pulley.

 

I took a 3/4 GR8 bolt added a 4.5" pulley,  drilled a hole for shear pin through one of the allen key holes. Then I  drilled a hole in the center using as a guide a set of bushings  to 1/4" for a pilot hole then when bigger  and tapped  to 3/8 fine.

 

Then took a 3/8 GR8 bolt and tapped  2.5" and then inserted into the 3/4" bolt (added blue locktite) and cut the head off.

I noticed you have one but I was going to tell you that I have a pulley that mounts on the fly wheel with three bolts that is about that same size.

[Goldnboy 959]

Managed to get the pump pulleys aligned, head bolts in with spacers. Got to get hose clamp for tank and another 90 elbow.  Time to remove and paint for when a warm snap happens  again this winter. I think a rubber hose will still be acceptable for the tank to pump what do you guys think?

[Achto 27,913]

Rubber hose should be just fine. My C145, C141,& 520 use rubber hose to run from the back of the tractor all the way to the front.

[Goldnboy 959]

I finished painting  the engine and have assembly  complete  before it gets installed to the tractor.  I added some ATF and it seems to flow to the pump sufficiently for the restriction to the hose angle. Does anyone  fabricate  starter  generator  covers? The ones by wheelhorse  I believe  will not clear a 4.5" pulley.

[RandyLittrell 3,885]

Looking good! There are quite a few pick-n-pull yards in KC, you could probably find a hose with a bend already in it already. Wish I was a little closer, would love to check out your setup!

[Goldnboy 959]

Got started again on this...

 

It fits !  Now on to changing the rockshaft 

[Cvans 1,009]

Nice compact setup. 

[Stormin 9,981]

Neat!

[littleredrider 409]

that's pretty cool. I have a pump off an old ford for a snow plow. I have the pump, valves, lines, but no cylinders. I've been looking for a way to mount it, now I think I found a way!! But, don't think I'm gonna have the room under the hood of a 606 with a 16 horse kohler, that takes up quite a bit of territory. 

[Goldnboy 959]

I was able to get the rockshaft installed, the control valve, and the lift cylinder.  Unfortunately  the clutch  pedal rod from a 8 speed  is straight  and bumps into the cylinder  lines, I have another clutch rod from a hydro, however  its a few inches  short.  Guess i will need to lengthen the one from a hydro to the correct  length with a coupling  nut. Had a visit  today from Don Thraen with a "Horse"  aka walk behind  tiller. 

[Tractorhead 9,065]

Huh, missed that thread because forgot to follow.

 

the new Hose looks much better in fit.

 

btw. Good solution with the Pulley

Very interesting set up you have put together they're definitely a great service motor. What are your plans from here?

of course you know we will have to require a video of it running

You've done a beautiful job on this but you just have to do something with that kinked hose. It's going to give me bad dreams tonight. 

Try putting a spring inside it to help hold it's shape. Just make sure it can't drop into the pump.

I did change that, it made me delay this before I refreshed the GT1848  in another thread, might not be able to see in the picture with the hood down,  but it now it goes down from tank with a preformed hose with a 90 bend  to a 90 elbow connected  with a hose to another 90 elbow and then back to another preformed hose 90 bend to end to pump. There is a little bit of drop down  but not much. I will post a close up  picture in the future.
