Crazy idea?

Most car pumps Iv seen spin at about crank speed. Your drive pulley on the alternator is spinning almost 2x crank speed. May be ok to run the pump at 2x but ? necessary. Its just more power stepping up through that small pulley alternator drive. If you could find a short multigroove/serpentine belt for the secondary it might reduce the pulley groove depth overhead enough to ease making prudent speed choices. - - More efficient too.

I like that multi groove belt idea. Easier to machine too. Lots easier. Cars, especially small cars, tend to rev higher than the 2700 max my engine spins. So a small car pump looks even better. I can look at pulley sizes at the wreckers to see if any pumps are being over driven. And it may seem crazy, but why not, that's the theme, but I could go as large as 7.5 inches on the pump pulley without running into clearance issues.

Once you get the pump+reservoir, then something like this to finish the job.

hey hey hey ! I love the NEW forum and the working SEARCH tool.

I found this thread again on PS for YM Yanmars

Power steering install on my Yanmar 2210d with Koyker 120 loader

Ok guys I have my PS install done and working like I want it to. I am sorry a head of time, I forgot to take a few pictures as I went a long but will do my best to describe what I did, or what happened. Tools you will need, 10mm wrench and short socket, 17mm, 19mm wrench, 3/4" wrench or...

OR check out the John Deere kits that fit our YM series machines. Be sure to review the JD compact 50 Series as those kits would be closer to a perfect fit.

Today I was offered a pump from a Honda. At least the guy thinks it's a Honda pump. He showed me pictures with a tape measure in the picture. It is quite small. It has an approximately 4.5 inch diameter multigroove pulley. I think it will be perfect. I will need to attach a fitting of some sort to the high pressure outlet. Maybe I can get a short length of hose crimped on and have the proper fitting crimped into the other end of the hose. I want to be able to change the long hoses easily in case they get damaged. They will, after all, be exposed somewhat under the tractor. Since it looks like I'm just getting a pump I will still need to buy or make an oil reservoir for the thing. I guess I will need to look at power steering reservoir capacities to know how big to make my reservoir.

If I need to I will just TIG braze a fitting to the high pressure pipe that comes out of the pump. This is an easy job. I think I will just buy the correct fitting and TIG braze it. No need for paying for crimps.

My seat of the pants feeling is that the power steering will be drawing no more than 3 HP at 2000 RPM. The alternator is being over driven by about 2 to 1. So 1000 engine RPM equals 2000 RPM alternator speed. This means that my power steering pump will be driven at approximately the same speed. Furthermore, the vee belt driving the alternator can deliver this amount of HP at the speeds involved. Anyway, more to come,

Looking forward on how this shapes up.

It would be higher than the water pump but will not fit directly above it. I really need to go to the Pick and Pull auto dismantlers and look at power steering pumps. It would be really nice if I can find a pump that has its own reservoir and fits in the space available. I would rather avoid a separate reservoir, especially since the one from the donor car may not fit where I can put one. Still, I can easily weld one up. I have the material, equipment, and skill needed to do the job.

I have a few Toyotas. There SUVs so I don't know cars but the smaller one is basically a Camry running gear. They all seem to have remote resivoirs, mine do. The pump is fairly small and so is the pulley if I remember right. I have not had my hands on the Highlander one but I have removed the one on the Sequoia for a timing belt job. Its pretty compact. Its the same as the one on the tundra. I have a first gen Sequoia which was the smaller tundra.

I have looked at every vehicle and tractor engine I have. They all spin clockwise when viewed from the front. This of course translates to CCW when viewed from the seat.
All the engines I looked at were mounted in line with the long axis of the machine.
Today I picked up a power steering pump from what was most likely from a Honda car. It probably had a transverse mounted engine. This means the power steering pump could have been mounted on either end of the engine. A person would think that by looking at the intake and exhaust of the pump inlets the rotation could be easily determined. Unfortunately the way this pump is made the direction of rotation is ambiguous. I am going to be talking to a friend who owns an import car repair business if he can help me. Fortunately he owns a 2310D. (I wish mine was a 2310D instead of just a 2310) and he would also like power steering. So he is interested in my little project.
I am glad forums like this exist for the free sharing of experience and knowledge. Though I don't know whether I have gained more or given away more knowledge since I started participating in knowledge sharing on the internet way back in the 80s I know I have benefited greatly from sharing and the knowledge I have gained would have cost me more than I could afford if there was a price.
All that said I will continue posting about my progress and will start posting pictures when appropriate.
I originally wanted this project to be one that could be done with typical tools available to the average equipment owner. But there will be some machining involved. So to make this project cost as little as possible I will post prints of any machining done as well as how I did the machining. That way the info could be used by hobby machinists as well as professional ones. The same goes for any welding.
I will also post my misteaks, er, mistakes. We can all learn from them too.

OK, first mistake. I forgot to say that when I picked up the pump today it already had a short length of the high pressure hose attached, 4 inches or so. Now I have a decision to make. Should I have a fitting crimped into the hose that I can thread my new hose onto or should I TIG braze a similar fitting to the high pressure tube coming from the pump? The tube comes off of the pump with a couple screws so it can be removed easily and then cleaned for the TIG brazing.

On to to oil reservoir and which oil to use.
I was told in a reply to a post I made about adding power steering to my YM2310 that a certain John Deere oil would work. I will look up that post and most likely use that oil. At this I would rather risk my free pump than the cylinder/valve combo that I bought and may be hard to find seals for.
There are several reasons I think I should use a stock Honda car power steering reservoir. Since it is plastic it will be resilient. If I make one from steel, aluminum, copper, or brass, the reservoir will be relatively stiff compared to plastic. So it will need to be isolated from vibration. A metal one will also need to have the the tubes coming from it sized properly for the hoses. These tubes will need to be made such that they will not crack at the reservoir/tube interface. They will be at low pressure though so that makes things a little easier. The reservoir will also need a cap. Plus it will be advantageous to have some sort of level indicator.
Though I have all the materials, skills, and tools to fab up reservoirs complete with level markings, and I can make cool looking caps too, I think a stock plastic reservoir will serve me, and the next owner, best.
A polished brass, aluminum, or stainless steel reservoir would look great. And even though I'm retired and now have more time for projects, this is one where I need to spend my time being practical. I am putting power steering on a tool that should have had it to begin with. Other folks with the same type of tractor will probably agree. They want a tool that works well and is a good value. So they don't want to spend a lot of time and money to make their tractor easier to drive, but will spend some time and money and elbow grease to make their small tractor more productive. That way some old fart like me can spend a little more time enjoying a beverage on the front porch bragging about the power steering install.

Eric,

John Deere Hy-Gard J20C or Yanmar TF-500A (same stuff). Thus, the same hydraulic fluid for the PS and the 3PT and loader all work. IF you are really fussy, Mopar ATF+4 as it's full synthetic.

Just an FYI, the YM2310 and the other machines above a YM1720 did come with the option of having OE PS.

In fact Yanmar in their literature boasted about offering PS.

Member California here can tell you the 'leaking' troubles with the OE design too. LOL

IF I had to PS my machine, I would go the electric assist PS option. No hoses, no pump, no belts, just mount and plug the connector in.

Yeah, well, I already have the cylinder made for this tractor, the one that Hoye sells. And now it looks like I have a pump that will work. Plus, those electric units are spendy. I hope I don't have issues with leaky stuff but I do know how to rebuild hydraulic cylinders if it comes down to that. Besides, using the electric option obviates my crazy idea which would deprive me of the fun of making stuff.
