help with ym 135 hydraulic tap

[green yanmar]

ive checked several of the threads and cant quite find exactly what im looking for.first i have a ym135 identical to boatamike machine,can i simply attach hoses to the two pluds under the seat where the little valve is,if so do i need a haedless plug as needed in other machines?and what is that valve for anyway?ive looked all over for the in and out as reffered to in other threads but no luck. could i drill and tap the intermidiate block between the pump and the in on 3pt?help!!!!!!!!!!!any info would be appreciated

...and what is that valve for anyway?...

Typically there are two valves under the seat, although some models only have one. If it's the valve directly under the front of the seat and whose stem faces forward and whose handle is reminescent of a water faucet, it's the 3pt safety lock valve and should be left open in normal operation. In closed position it hydrostatically locks the 3pt and prevents it from lowering.

If it's the valve on the side, whose handle looks like a dowel with a pin through it, and pivots fore and aft, it is the 3pt drop rate control. Not all models have this valve. It regulates the speed at which the 3pt lowers.

Since I am woefully ignorant of all matters hydraulic, I'll refrain from offering my opinion/advice on the other topics of your post.

I'll try to help, but I'm sure there are others more knowledgeable than I. On my 155D there's a divider block in the high pressure line between the shifter and the steering column. I gather you can obtain a block that doesn't connect the two lines like the stock block does, but lets you essentially splice in line. I copied these from pages in my owners manual and service manual. Perhaps you can make sense of it.



I've never seen these blocks available. If you find a source, let me know. I'm sure it would be easy to make for someone handy on a mill.

Hi,

I too have a YM135. When I built my loader, I did as explained earlier, I removed the top of the junction block near the shifter and had a new one mide to splice into the line. I ran my return into a custom made cap with a quick connect that repaced the filler cap for the hydraulic fluid.

I can take some pictures if you guys are interested.

Hi Green,
I have the original Yanmar loader for my machine which I think is the YFL155. It's hydraulic system is totally seperate from the tractors. There is a reservoir in the right upright of the loader and a pump behind the front "bumper" that is driven from the front PTO. It's a pretty slick setup.

I've attached some pictures. By the way, these pictures are when I first got the tractor. I've since acquired two sets of matching wheels. Are you thinking of adding a loader to the 135?

Oops... forgot to load the pictures.

im actually fabricating the loader myself well its really a retro fit of a loader i purchased used off a ford 8n it was agood deal at 200 dollars for valves ,cylinders hoses etc,just alot of cutting welding and fabricating,but i love doing this tinkering and it keeps me busy,just trying to figure the best way to plumb it up.
